Prevention of spider mites on cucumbers. Effective measures to combat spider mites on cucumbers. Preventive measures against spider mites

Good morning, dear reader! My mother is an avid gardener. She knows almost everything about all plants and pests. But last year, her crop began to be attacked by spider mites. For her, this was the biggest tragedy, since mommy really loves pickled cucumbers, and then her harvest was lost.

She did not notice this problem immediately, which aggravated the situation. Therefore, when the situation manifested itself, it was necessary to solve the problem immediately. Mommy first washed the plants, and hard to reach places sprayed with a special product. Then I removed the heavily infected leaves.

After much effort, we finally managed to save the remaining harvest. Now it was only necessary to support preventive actions. In this article you will learn: spider mites on cucumbers - how to fight them, what they offer from store-bought preparations and folk remedies to combat the pest.

Spider mites on cucumbers: how to fight, proven methods

Spider mites on cucumbers: how to fight

To get rid of mites, you must first carefully wash the plant.

Naturally, prickly cucumbers are very inconvenient to wash, so you can replace washing with spraying. All affected parts must be treated. Most often these are leaves. Sometimes the stems are also damaged.

Warm water or a solution of laundry soap is best for spraying. Inexperienced gardeners use detergents. This should not be done, as the composition may contain harmful components.

Significantly damaged leaves must be carefully removed and burned. Thanks to this, it will be possible to reduce the reproduction of the pest and limit its migration to other leaves or plants.

It is recommended to remove severely affected shoots.

During cloudy weather, cucumbers should be watered generously and then covered with film. Thanks to this, the humidity level will increase significantly, which spider mites are very afraid of.

In some cases, the use of chemicals is recommended. This may be a solution of Karbofos or Intavir. It is important to follow the dosage indicated in the instructions.

You can add a drug called “Temik” to the soil. This is a strong insecticide that will help kill pests.

Spraying with phosphorus and sulfur preparations is recommended.

Chemical attack

Experienced experts say that spraying with various insecticides, if available spider mite useless. In this case, it is better to give preference to acaricides or insectoacaricides. These drugs cannot be called completely safe for human health, so today various drugs that have an intestinal-contact effect are actively used.

Processing with such compounds must be done very carefully. This will require repeated processing, which will destroy the younger generation. It is carried out depending on the temperature:

At +20º C, plants are sprayed 3 times with an interval of 9 days;
At +30º C it is necessary to spray 4 times with a break of 3-4 days.

If the air temperature rises significantly, more treatments will be required at shorter intervals. Otherwise, such a procedure will be useless. This is explained by the fact that it takes literally 3-4 days to lay eggs.

You need to spray the plants in the evening, when the sun is not too hot. If you carry out the treatment in the middle of the day, the toxic substances will quickly evaporate and will not have a detrimental effect on pests.

Many experts recommend spraying cucumbers as a preventive measure, since if there are a significant number of insects, the recommended dose will be useless. If you increase it, it can negatively affect human health.

It must be remembered that long-term use of one drug leads to the formation of immunity in spider mites. It is also known that no more than 50% of the pest dies in one treatment. This is explained by the fact that the web repels water, and therefore it is quite difficult to achieve a better result.

Common chemicals against spider mites:

If desired, you can replace the above-mentioned chemicals with other means. Thus, plant poisons are often used, which pose minimal danger to humans. Treating plants with such substances must be done very carefully. In this case, you must adhere to the dosage specified in the instructions.

To combat spider mites when their population has already grown, it is advisable to use chemicals.

It is important to remember that since this pest is not an insect, insecticides are useless against it. Acaricides are used to kill arachnids. This group of plant protection products gets its name from “acari” (mite) and “cide” (to shorten).

Conventionally, the group of acaricides is divided into:

Specific acaricides. Contain sulfur, bromine or their derivatives. They act exclusively on ticks.
Insecticides-acaricides. Complex poisons that act on both insects and arachnids. Pyrethroids or organophosphorus compounds, and less commonly, inorganic sulfur preparations, are used as toxic substances.
Acarofungicides that also act on spores of pathogenic fungi. Since mites often carry them on themselves, infecting a weakened plant, the use of such drugs in the fight against mites is justified and effective.

All acaricides that can be purchased commercially belong to the third hazard class.

That is, they are of little danger to mammals. When using them, it is enough to adhere to the usual safety rules in such cases. The respiratory organs are covered with a cloth, gauze bandage or respirator.

During the work, choose clothes that cover the body as much as possible. Acaricides have a sharp bad smell. The reason is in two phases of damage: contact and gas. The spider mite must “inhale” the poison. The smell does not indicate any particular “harmfulness” to humans.

Naturally, all work is under conditions open ground carried out in the absence of wind. There are two reasons for this: protection from accidental droplets and processing accuracy. When working with this group of drugs, it is more important to protect the environment:

Avoid getting into open waters, as these drugs are dangerous for fish;
Do not apply during the flowering period, as acaricides are toxic to bees.

To get rid of spider mites on cucumbers, “biological” preparations have also been developed. These include, for example, Fitoverm. It has the same hazard class and requires compliance with the same safety measures during processing.

Its difference is that it can be used during the growing season. Fruits after spraying with Fitoverm can be collected within 48 hours (when using conventional acaricides - at least a month).

Aversectin is a biologically active toxic substance obtained as a result of the life activity of producing crops, does not accumulate in plant organs, but self-destructs. In order for the spider mite on cucumbers to actually die, you must adhere to a number of rules.

Firstly, all acaricides have only a contact effect and are not systemic drugs.

That is, to get rid of a spider mite, you literally need to water it. The leaves are sprayed on both sides, paying special attention to the growing point and the lower surface. In a greenhouse, spider mites can hide not only on cucumbers, but also on supports, in the folds of the film.

Secondly, treatments must be carried out strictly periodically: acaricides do not affect eggs.

At a temperature of about 20 degrees, three treatments with a period of seven days are usually sufficient. At daytime temperatures of 25–30 degrees and above, young spider mites hatch faster.

In this case, treatments are carried out every three days, increasing their number to four. In a greenhouse, where the temperature is higher, spider mites are poisoned according to the latter scheme. Failure to comply with deadlines will negate all efforts to combat the tick.

It is important to remember that acaricides (especially for preparations with aversectin) quickly decompose under the influence of high temperatures and ultraviolet radiation. Work to rid cucumbers of spider mites is carried out in the cooler evenings, otherwise they will be of little use.

It is advisable to add a drop to the working solution detergent so that the poison “sticks” to the leaves and does not wash off.

Before spraying, remove as much cobwebs as possible, which serve as a “roof” for spider mites; its dense structure will protect pests from droplets. Under the influence of acaricides, the tick stops feeding after 8–12 hours.

Spider mites, like many arthropods, have an adaptive mechanism that allows them to “resist” the harmful effects of poisons. Since their generations change quickly, there is a risk that over the summer they will “grow” spider mites that are tolerant to a certain toxic substance.

Therefore, it is advisable to change acaricides with each treatment.

It is important to remember that biological acaricides do not combine well with chemical ones. Timely use of acaricides at the first detection will help save the harvest of long-awaited cucumbers.

Folk remedies

To avoid the appearance and active reproduction of spider mites, it is recommended to plant cucumbers together with various flowering plants. This is especially true for marigolds and calendula. Experienced gardeners often use turpentine. It is necessary to pour the liquid into a container and place it without a lid near the diseased plant.

The shoot, along with a jar of turpentine, is covered with a thick cloth and left for at least 3-5 hours. Experts often prepare herbal infusions for spraying:

200 g of a mixture of garlic and onion peels are diluted in 10 liters of water;
400 g of crushed calendula flowers are mixed with 2 liters of water and infused for 5 days; before use, the infusion must be diluted with the same amount of water;
400 g of crushed dandelion leaves are placed in a container with 10 liters of water and left for 2 hours;
300 g of sorrel roots are poured into 10 minutes of water and left for 3 hours;
Dandelion leaves, onions and garlic are passed through a meat grinder, a glass of this pulp is mixed with a spoon of any liquid soap and diluted in 10 liters of water, after a couple of hours the composition must be filtered;
1 kg of dried yarrow is poured into 2 liters of boiling water and left for 40 minutes, then the liquid is poured into a container with 10 liters of water and left for 2 days.

To remove spider mites from the surface of the plant, cucumbers need to be washed with warm soapy water. For this purpose, you must use only laundry soap. Its foam can be left on the shoot. This treatment is good for small numbers of spider mites.

It must be remembered that the pest does not tolerate UV rays well, so the seedlings can be irradiated using an ultraviolet lamp. One session lasts literally 2 minutes. The procedure is repeated once a week, due to which the number of insects is significantly reduced, and the resistance of cucumbers to most diseases increases.

This treatment must be carried out very carefully so that the rays fall only on the lower surface of the leaves.

Spider mites are serious pests, so you should use several different products to combat them. Even if, after treatment, no insects are visible on the plants, it is necessary to carry out another procedure a week later for preventive purposes.

You can take the common datura, chop it finely and dry it. Take about 100 g of the plant, add 1 liter of water and leave for about 10 hours. Then the solution is filtered, water is added to make 10 liters of liquid and the cucumbers are sprinkled with it.

You can use aloe leaves, which will require about 2 kg. The plant should be passed through a meat grinder and the resulting pulp should be filled with 10 liters of water.

Add 50 g of pureed laundry soap to the solution and mix everything well. All plants must be treated with this product: both affected and healthy. This method should be used once a week for a month. Then the procedure must be repeated.

The preparation is also prepared from tomato tops, which should be cut and dried. To 1 kg of this mixture add about 1 kg of chopped fresh tops. The resulting mass must be soaked in a bucket of hot water, add grated laundry soap (about 50 g) and leave for about 4 hours. After this, the solution is ready for use.

A solution of horse sorrel is often used, which will require about 300 g. It is poured with 10 liters of water and infused for about 3 hours.

A solution of hot pepper has proven itself well. Boil 100 g of pods of this plant for about 2 hours in 1 liter of water. Approximately 150 g of decoction and 50 g of grated laundry soap are added to a bucket of water. All these solutions are poured into a sprayer and the plants are thoroughly treated from all sides.

After harvesting, all cucumber vines should be removed from the greenhouse or plot and burned. In the fall, rooms where cucumbers grew must be disinfected with a formaldehyde solution, including the walls and ceiling, in order to destroy hidden pests.

Plants that will help in pest control

Plants can also be effective in controlling spider mites. Here are some of them:

Nosed aconite

Roots and tubers, roots and grass are infused in 70% alcohol. Before use, the extract is diluted with water in a ratio of 1:10, and then used against spider mites. Plants are harvested during the budding period.

Hogweed (Caucasian, Siberian, bearded; montigation downy, spotted)

Infusions of its dry leaves, stems and roots are used against spider mites (infuse 1 kg per 10 liters of water for 24 hours). Infusion recipe: crushed green parts are ground into a paste with water (1 kg of plant per 2 liters of water).

Squeeze out the liquid part, pour in 15 liters of water and, after infusing for 6-12 hours, separate the liquid part again and mix it with the solution obtained earlier. Raw materials are harvested before and after flowering, and during flowering - only the above-ground part.

Creeping bitterweed

Infusions or decoctions are used against spider mites. Infusion recipe: pour dry crushed plants with water (120 g per liter) for 24 hours or boil for 30 minutes after 6-8 hours of infusion. The liquid part is drained and diluted twice with water before use. The above-ground part or the entire plant is harvested during flowering.

Datura common

Its water infusions and decoctions are also used against spider mites. Infusion recipe: finely chopped dry plants (100 g per 1 liter) or finely ground powder from a dry plant (50 g per 1 liter) are poured with water for 12 hours. Then the liquid is filtered.

Decoction recipe: boil 1 kg of dry green parts of the plant (or 2.5 kg of dried or 3 kg of fresh plant material) in a small amount of water for 2-3 hours. After cooling, strain the broth and add to 10 liters. During flowering, the entire above-ground part of the plant is harvested.

Carpesium wormwood

Seeds and dry above-ground parts of plants are infused for 12-24 hours in water in an amount of 70-100 g per 1 liter, the filtrate is used to treat plants affected by spider mites. Plants are harvested during the growing season, and seeds are harvested after ripening.

Oriental goat's rue

Infusions of dry ground plants (90-100 g/l) after 24 hours of exposure and filtration are used in the fight against spider mites. Plants are harvested during the growing season.

Clematis Manchurian

Water infusions of fresh leaves (50-100 g/l) are effective against spider mites.

Bulb onions

In the fight against spider mites, water infusions of onion scales are used. Onion scales are infused for 12-15 hours. Concentration - 20 g/l.

Gray alder, artisanal alder

Water infusions (100 g/l) have a detrimental effect on spider and root mites.

Feverfew red (Caucasian chamomile), pink feverfew, Dalmatian chamomile. All plant mites die from 2% aqueous suspensions of chamomile powder.

blue cyanosis

An infusion of dry roots at a 10% concentration is effective against spider mites. What else needs to be done to defeat spider mites:

Clear greenhouses and greenhouses of plant debris and destroy them.
Dig up the soil.
Carefully destroy weeds in beds and around greenhouses.
Before laying greenhouses, wash boxes and frames with a 10% solution of caustic soda or iron sulfate.
Collect and burn single damaged leaves.
Spray with infusion of onion or garlic scales (200 g).
Treat with 70% colloidal sulfur (50-100g), keltan (20% sulfur, 20 g) in open and protected soils.

Home remedies for getting rid of spider mites on cucumbers

If the damage to cucumber foliage is insignificant, and the owners do not know how and how to get rid of spider mites on cucumbers, they will need the products that everyone has at hand.

Just 2 tablespoons of 3% hydrogen peroxide, diluted in a liter of water, will be a disastrous control measure for the voracious tick family.

It is advisable to spray with such a solution 3 - 4 times, at t around 20°C the interval will be 5 - 7 days, at t around 30°C - 3 days.
Such simple measures without the use of chemicals will neutralize the threat of cucumber bushes being destroyed by mites if they are applied in time.

Agrotechnical methods

Agrotechnical methods are the best prevention of infection of cucumbers by mites, since it is better to avoid the appearance of these arachnids. This is due to the fact that if they get started, it is very difficult to get rid of them.

Alternate planting of cucumbers with tomatoes, since mites do not develop on tomatoes.

That is, if too many mites have developed on cucumbers in a garden or greenhouse and it is not possible to get rid of them, next year Tomatoes should be planted in this place. Since mites do not live on tomatoes, they will completely disappear within a season.

Timely weeding and proper care taking care of plants: watering, fertilizing, loosening the soil, removing old leaves, etc.;

Plant with a significant distance between plants to make it difficult for ticks to move.

It is better to alternate beds with cucumbers with beds on which other crops will grow. In this case, if ticks appear in one of the beds, the others will not be harmed. If they are located close together, all cucumbers can be infected in a short time;

Cleaning the greenhouse or garden in the fall from all garbage, rags, and plant remains that must be burned.

In addition, a greenhouse or greenhouse can be disinfected, for example, using FAS or Climate sulfur bombs.

Deep digging of the soil, preferably in autumn period;

Creation high humidity(80% and above), it is considered optimal for plants, and unfavorable for mites;

Inspect plants for mites.

What is a spider mite and where does it come from?

The main thing you need to know about a tick is that it is not an insect. This arthropod belongs to the class of arachnids, family Tetranychidae. The most common member of the family is the common spider mite. It is he who attacks cucumber beds.

The pest has a cosmopolitan distribution, that is, its habitat covers almost the entire territory of the Earth. It is even found in Antarctica. Therefore, the fight against spider mites is an issue that is relevant for plant growers from all corners of the earth.

Spider mites are soft-bodied arachnids with a small, up to 0.6 mm, ellipsoid body, convex on top and flat below. The maturation process is divided into five stages and is accompanied by molting.

The larvae are translucent, greenish-brown; adults are most often reddish-orange or red in color. One of the larval phases is six-legged; adults, or adults, have eight legs. They produce webs. They can migrate long distances with gusts of wind.

The life cycle is short, taking less than a month. Reproduction rates depend on the characteristics environment. Favorable conditions: high temperature and low humidity. When air humidity is above 80%, it practically does not reproduce, so fighting spider mites in a greenhouse is always easier than in open ground conditions.

Does not tolerate ultraviolet radiation, stays on the shaded side of the leaf.

Spider mites are polyphages. Preference is given to certain host plants, there are more than 200 of them. But in the absence of food, “to taste” they can eat what they have. They pierce the outer covers and suck out the contents of the cells, depriving them of chlorophyll. They settle at the growing point and on young leaves.

The pest poses a threat not only to cucumbers, but also to many other plants. It can be found on crops grown both indoors and outdoors. It is quite difficult to combat such a pest, so it is important to recognize it in a timely manner.

Important! It is recommended to carry out the spraying procedure in the evening, since under the influence of sunlight the chemicals will quickly evaporate and will not be able to destroy pests.

The tick is characterized by a very small size. The female does not exceed 0.5 mm, and the male - 0.3 mm. Particularly voracious individuals who have found suitable food for themselves, for example, the juice of cucumber leaves, can grow up to 2 mm. The pest's body shape is elongated and elliptical. Females are orange-red in color and are highly fertile.

During the season, one female can lay about 8,000 eggs. Maturation occurs very quickly - in just a few days the egg becomes a sexually mature individual. If you do not hurry up and take pest control measures, you may be left without a harvest.

How dangerous

When a pest finds itself in a planted area or in a greenhouse, it immediately settles on those types of plants that are most convenient for its existence. Most often, cucumbers become such a crop. Mites take all the necessary nutrients from plant cells (feed on sap), which is why the leaves begin to wither and dry out so quickly.

As a result, due to cucumber disease, the plants die entirely. It should be noted that the females of such ticks do not sit still. After just 3-4 days, they begin to actively lay eggs, the number of which can exceed 400. Over the course of a year, such egg-laying processes can occur up to 20 times.

The most suitable air temperature for their reproduction is from 23 to 33° C. It is important to know that ticks reproduce and develop not only in greenhouse conditions.

There is a very high risk that they can also infect plants growing in the garden. What needs to be done in order to get rid of the cucumber pest as soon as possible? Of course, I would like to say that the means of combating ticks are very simple, but they do not always act as quickly and effectively as we would like.

Numerous studies and experiments have proven that you can get rid of the pest by simply spraying it big amount water or using ultraviolet lamps is absolutely useless. The tick larva is quite resistant and can counteract many negative external factors.

Therefore, it is so important to quickly select the very remedy that will quickly help you resolve this problem. Otherwise, there is a risk that you will be left without the long-awaited harvest.

Spider mites cause enormous damage to vegetables. By sucking out the contents of cucumber cells, it gradually brings the death of the plant closer. The pest is also capable of infecting the plant with various infections; it spreads gray rot bacteria. This leads to the fact that the plant loses its immunity and can become infected with other diseases.

Many people are interested in the question: are spider mites dangerous for humans? In this regard, you can be calm: the only harm (other than loss of harvest) that a pest can cause is nerves spent worrying. Spider mites cause damage to a variety of plants, such as beans, melons, tomatoes, chrysanthemums, dahlias, hollyhocks, hydrangeas, gooseberries, roses, spruce, juniper and apple trees.

Signs of damage to cucumbers

The main signs of damage to cucumbers include:

Typically, spider mites are located on the underside of leaves, so you should pay attention to them more often. The web that wraps around plants serves as a springboard for pests to move through the foliage.

Damaged crops slow down their growth, and leaves that were not damaged turn yellow.

To understand the ways in which spider mites appear on cucumbers and how to deal with the horde of these gluttons, you need to know their habitat.

The small harmful bug with which to fight, about 0.5 mm long, is colored brown or red and is endowed with 4 pairs of articulated legs in the adult stage and 3 pairs in the larval stage.
It develops in 5 stages - egg, larva, 2 stages of nymph and adult.
Larvae and nymphs are greenish with dark areas on their sides.
Females hide in the ground for the winter.
It loves dry, hot air; under such conditions, the larvae hatch quickly - within 3 days.
The tick does not live long - less than a month, but it manages to reproduce well, which complicates control measures.
It settles on the back side of the leaves, pierces their flesh and sucks the juice from the plant, depriving it of chlorophyll.
It leaves behind damage on the foliage in the form of a marble pattern - whitish lifeless spots and a thin but dense milky cobweb.

Recipes for controlling spider mites on cucumbers, as well as measures to prevent them, are largely based on the ways in which the pest appears.

Spider mites usually crawl onto cucumbers from the ground after wintering, when the soil warms up sufficiently, attacking the growing greenery.
Weeds that grow in the garden before cucumbers become breeding grounds for ticks.
Seedlings from greenhouses and greenhouses are another likely gateway for cucumbers to be infected by a horde of pests; they provide an excellent environment for their habitat.

For your information! Spider mites, in addition to their own damage, can “reward” vegetables with gray rot spores. It is better to initially prevent its appearance than to try to get rid of it later - fighting it, alas, is really labor-intensive and not always successful.

Why is it so difficult to get rid of spider mites?

Most gardeners who are faced with this problem claim that even chemicals and herbal decoctions do not always help in the fight against them. This is due to the high resistance of spider mites to insecticides.

Spider mites easily get used to and adapt to almost all poisons. The difficulty of controlling ticks is also due to the fact that:

They are not immediately noticeable;
Females lay eggs within 4 days of emergence;
Ticks are able to adapt to chemicals;
High speed reproduction.

What difficulties can you encounter when getting rid of a tick?

The task is complicated by the small size and weak signs of the appearance of the pest at the initial stage of plant infection. In addition, this insect species reproduces rapidly. Over time, the pest develops resistance to certain drugs; some drugs even show ineffectiveness even at the first use.

To get rid of spider mites on cucumbers, you need to apply the treatment several times. Often, even spraying the product twice does not produce results, the reason for this is the high reproduction rate.

If the plant is severely affected, the effectiveness of the drugs is reduced, since the web takes on a significant part of the moisture, protecting the mites.

It must be remembered that only using a large amount of the product will give good results, savings in in this case will lead to the spread of the disease. Sometimes a pest can only be destroyed with a concentrated solution, which can negatively affect human health.

Since it is very difficult to comply with high microclimate requirements in greenhouses, pests sometimes appear in them and infections develop. The reason for the appearance of pests and the activation of pathogenic organisms may be incorrect temperature conditions, inappropriate air humidity, untimely harvesting of plant residues, excess or deficiency of fertilizers and contaminated soil. In this article we will tell you, where do spider mites come from on cucumbers in a greenhouse, what means are used to destroy them, and what preventive measures will help protect the greenhouse from this pest.

Description of the pest

Spider mite - an arachnid arthropod of red, orange, yellow-green or whitish color, usually less than 1 mm in size. These sucking pests settle on the underside of leaves and feed on the cell sap of the plant. Ticks are incredibly prolific: in one season they can produce up to 20 generations. The main danger of these pests is that they are carriers of the cucumber mosaic virus.

As soon as spider mites appear in a greenhouse, they spread very quickly, and as a result of their vital activity, plant leaves become depleted, dry out and die, which negatively affects both the development of cucumbers and their fruiting. The most comfortable temperature for these pests with average indoor humidity of 23-33 ºC, that is, greenhouse conditions are simply ideal for spider mites.

Signs of the presence of mites on cucumbers are:

discolored spots and spots on leaves;
barely noticeable cobwebs;
slow growth and development, yellowing and drying of plant leaves.

Prevention of spider mites on cucumbers in a greenhouse

If you don't want to fight mites on cucumbers every year, carry out preventive measures:

at the beginning of each season, disinfect the greenhouse with a sulfur bomb: this way you will rid the room not only of ticks, but also of other pests, as well as fungi and viruses;
after harvesting, remove all plant debris from the greenhouse, and at the beginning of the next season, change the top layer of soil 20 cm thick on the beds;
alternate beds of cucumbers with beds of tomatoes: mites do not multiply so quickly on tomatoes;
plant marigolds between the bushes, the smell of which ticks cannot tolerate;
regularly fight weeds and remove them from the greenhouse: it is on the weeds that pests first settle;
strictly follow crop farming practices and try to leave slightly larger gaps between rows so that mites do not spread so quickly;
Maintain high air humidity in the greenhouse - 80-85%. For cucumbers this is a normal level, but for mites at such indicators it will be damp;
regularly inspect the plants so as not to miss the moment when ticks appear: the sooner you find them, the higher the chance of quickly getting rid of them;
If mites are found, immediately start processing cucumbers folk remedies: plants are sprayed every two weeks, and if the mites have multiplied, then weekly treatments will be required;
You can destroy spider mites with the help of their natural enemies, phytoseiulus - predators among ticks; it is enough to spread several leaves with phytoseiulus around the bush affected by mites;
If folk remedies fail to rid cucumbers in a greenhouse of spider mites, use acaricidal preparations.

Traditional methods of killing spider mites, of course, are not as effective as chemical acaricides. The advantage of herbal preparations is their low toxicity to humans and the environment, so if there are few pests, try to do without chemicals. The following can help you in the fight against spider mites:

solution 30 ml ammonia in 10 liters of water: wipe the cucumber leaves and spray the greenhouse with the solution;
wormwood infusion: 800 g of dry wormwood herb, pour 10 liters of water, leave for 2 days, then cook for half an hour, cool, strain and dilute 1:1 with water - this composition will help you get rid of many pests in the greenhouse;
decoction of tomato tops: pour 4 kg of chopped tops into 10 liters of boiling water and cook over low heat for 30 minutes, then strain, for every 2 liters of decoction add 30 g of grated laundry soap and stir well - the decoction is effective against ticks and aphids;
garlic infusion: leave 150 g of dried garlic leaves and peels in 10 liters of water for 24 hours, strain and immediately treat the bushes;
mustard infusion: 200 g mustard powder pour 10 liters of water, leave for half a day and strain;
infusion of potato tops: pour 1.5 kg of chopped tops with a bucket of water for 4-5 hours, strain and use for spraying.

Treating cucumbers against mites in a greenhouse with chemicals

Since ticks are not insects, but arachnids, acaricidal chemicals are used to kill them, not insecticidal ones. the most effective of which are:

Plant-pin- a means to combat ticks and aphids, which is produced in the form of sticks: they are stuck into the soil around the plants, during watering they dissolve and release the active substance butoxyraboxim, which affects ticks. The drug is intended to destroy pests at an early stage of plant damage, the protection period is 1-1.5 months;

Spider mites on cucumbers are almost invisible due to their small size and lifestyle (they live on the inside of the foliage). This inconspicuous pest causes enormous harm. As a result of its vital activity, plants die: they become stained and dry out. A web is one of the obvious signs of an insect.

Body size is up to 2 mm, the color is often greenish, sometimes yellow and brown individuals are found. Spider mites live on cucumbers only in conditions acceptable to them: dry and warm air. In winter, insects do not die, but hide in the soil (upper layers), manure, and leaves that have already fallen. In addition, any greenhouse corner is suitable for wintering. The cucumber mite spreads in the wind, which is facilitated by the small size and light weight of the insect.

Habitat signs

Females have a greenish-yellow color, size up to 0.5 mm. Males are smaller (approximately 0.4 mm)

The pest reveals itself by the fact that its vital activity leads to changes in the structure, shape and color of plant leaves:

Light dots are detected, which later develop into spots. Such changes first become noticeable with inside leaf.
The appearance of an almost barely visible cobweb.
Change in foliage color - it turns yellow.
The plantings are far behind in development.

Features of wrestling in different conditions

When thinking about how to save cucumbers, as well as other crops, you should consider different methods of influence. The method of growing the plantings is also taken into account.

Cucumbers grow in open ground

An important feature: after the harvest has been harvested, the remaining plants are destroyed. Other recommendations:

The soil is dug up before new sowing. This is usually done from autumn until frost.
Weeds are regularly removed as they provide a suitable environment for the initial development of insects.
As the plantings grow, they are inspected. If affected areas are found, they are removed and then destroyed. Moreover, it is better to burn leaves with signs of pest activity.
The rule of crop rotation is followed: cucumbers should be alternated with other plants, for example, tomatoes, cabbage.
In case of significant damage, when obvious signs of tick habitation (webs) are noticeable, the bush is treated with drugs (pesticides, insecticides).

Cucumber leaves affected by spider mites. In case of significant damage, obvious signs of pest habitation (web)

Rules for getting rid of pests in a greenhouse

The greenhouse is characterized by the most suitable conditions for ticks to live. This insect prefers to settle in places with a dry microclimate, so the main measure to combat it in a greenhouse is to increase the humidity level to 70% or more.

Other measures:

Regular change of soil (top layer). This measure is implemented after the harvest has been harvested.
If a spider mite has settled on cucumbers in a greenhouse, after harvesting the trellises are treated at high temperature using a gas burner.
Smoke bomb treatment.
Application of phosphate fertilizers.

What difficulties can you encounter when getting rid of a tick?

To get rid of spider mites on cucumbers, you need to apply the treatment several times. Often, even spraying the product twice does not produce results, the reason for this is the high reproduction rate.

If the plant is severely affected, the effectiveness of the drugs is reduced, since the web takes on a significant part of the moisture, protecting the mites. It must be remembered that only using a large amount of the product will give good results; saving in this case will lead to the spread of the disease. Sometimes a pest can only be destroyed with a concentrated solution, which can negatively affect human health.

When thinking about how to treat cucumbers, it is recommended to pay attention to a number of preparations: Plant-Pin, Ethisso, Actellik, Fitoverm. The choice of product should be made taking into account the degree of infection of the plantings, since not all active ingredients differ in the same level of effectiveness against spider mites.

Plant Pin

The active compound is butoxycarboxim. Destroys various pests, but does a better job of cleaning plants from mites and aphids. The release form is unusual - sticks. They are buried in the soil next to the seedlings. The release of the active substance occurs during watering of plantings.

This product is intended to protect indoor plants, however, proves to be effective even in greenhouse conditions. The main advantage is the residual effect, which lasts for 1.5-2 months. after initial use. Once you start treating plants, you can expect positive results already on day 2.

Etisso

The active substance is dimethoate. Release form: sticks. They are used in a similar way as previously in the case of the product of the brand considered: when watering, the substance is released and penetrates into root system, from where - to the ground part of the plant. The residual effect lasts up to 8 weeks. To treat a larger area, more sticks are used.

Produced in liquid form. The product is offered in ampoules of 5 ml. This amount is enough for a water volume of 1.5 liters. The drug is sprayed over the plants. Considering high level toxicity, all manipulations are carried out wearing protective gloves and a gauze bandage.

Fitoverm

When thinking about how best to deal with spider mites on cucumbers, you should consider different means. One of the most effective is Fitoverm. Its main disadvantage is the rapid adaptation of pests to the effects of the active substance (aversectin C). To avoid this, it is better to use Fitoverm alternately with other products. The drug is offered in the form of an emulsion, container volumes: 2 ml, 5 ml, 10 ml and 5 l.

Home Remedies

The fight against small spider mites on cucumbers is also carried out using available substances that are often at hand.

Popular means:

Hydrogen peroxide (3%). You will need 2 tbsp. l./1 l of water. The frequency of spraying is 3-4 times, the interval between procedures depends on the air temperature: at +20 degrees, re-treatment is performed after a week, at +30 degrees - after 3 days.
Turpentine. The substance is poured into containers previously buried in the ground. The fumes will kill the tick. To prevent them from affecting the plants, the containers are periodically covered with woven material.
Tobacco dust is sprayed over the plants.
Ammonia (1 tsp) is diluted in 1 liter of water. Spraying is carried out according to a similar scheme as in the case of peroxide.

Affected areas of plants can be washed with soapy water. A short exposure to UV rays helps remove mites; to do this, a lamp with the appropriate characteristics is directed at the plants.

Plants that negatively affect pests

In addition to the main means of treatment, you can use natural methods:

Peeling of garlic, onion. To prepare the infusion you will need 200 g of raw materials, 10 liters of water.
Dandelion leaves (400 g), 10 liters of water. After combining the components, they need to be left for 2 hours.
Sorrel root (300 g), a bucket of water. The recommended preparation time for the infusion is 3 hours.
Pre-dried yarrow (1 kg), 2 liters of boiling water. Having combined the components, leave them for 40 minutes, after which the finished product is added to a bucket of water. The duration of preparation of the infusion is 2 days.

Biological products

If there are spider mites on cucumbers, what is the best way to fight them? To do this, use products that are safe for plants and humans:

Vertimek – contains the substance abamectin. Known for its effectiveness.
Aktofit: active substance – aversectin. Provokes the death of spider mites.
A number of drugs based on one substance avertin: Akarin, Kleschevit, Agravertin.

Tips for summer residents:How to fight cucumber mite

The tick provokes unpleasant diseases. In order not to have to decide how to deal with it, it is necessary to take into account the living conditions of this pest. Under certain conditions, the reproduction process occurs more intensively: comfortable temperature, low humidity.

Spider mites are considered to be quite a dangerous garden pest. It often causes the destruction of many crops, including cucumbers. It is quite difficult to detect the pest in the initial stages. And with strong reproduction, extermination of the tick becomes a real problem.

Spider mites are so small that it is impossible to pay attention to their small clusters. Hiding on the back of the leaves, the pest multiplies, significantly increasing its numbers. The mite forms a web in which young individuals grow. If no action is taken, after a certain time the pest will colonize the entire garden bed, greenhouse or greenhouse.

It is greenhouses and greenhouses that are the ideal place for the development and active reproduction of spider mites. The pest feels comfortable at moderate air humidity and temperatures of 20-30 degrees. But warm summer days allow arachnids to settle on open beds. During the year, the female lays eggs about 20 times. Each clutch can contain up to 400 eggs.

What does the poutine mite look like on cucumbers photo

It is quite difficult to notice an arachnid pest. But with a large accumulation of it, a person can pay attention to certain signs of the presence of a tick:

Plant growth slows down significantly;
Small dots are visible on the bottom of the leaves;
The plant is covered with small cobwebs;
Yellow and dark spots appear on the leaves. These are exactly the places where the pest sucks out the juice.

Spider mites spend the winter quietly in top layer soil. That is why greenhouse owners are recommended not only to carry out high-quality disinfection, but also to change the soil annually. Although this does not provide a 100% guarantee that the appearance of this pest will be avoided. After all, he can get into new ground with a strong gust of wind.

How to save cucumbers from spider mites

It is important to remember that the sooner the pest is detected, the more crop you can save. Under comfortable conditions, spider mites can settle on almost any plant. Since cucumbers are often grown in greenhouses, they are the ones most often attacked by these pests. Mites suck out all the necessary nutrients from the plant, leading to dehydration and drying out of the garden crop. Since spider mites develop quite quickly, it is necessary to take appropriate measures as soon as they are discovered. A whole range of measures will allow you to save cucumbers:

It is recommended not only to remove the old soil and use new soil, but also to change the location of planting the cucumbers annually.
Ticks often spend the winter in the remains of old plants. That is why it is necessary to take care of their thorough cleaning. Proper care of your garden bed or greenhouse will increase the effectiveness of pest control.
Carefully study the rules for arranging plants in the garden bed. During planting, it is necessary to maintain the correct distance between the bushes. Thanks to the increased distance between them, you will be able to detect and destroy the pest even before it settles on all the bushes.
When growing cucumbers in greenhouses, it is recommended to maintain high humidity. Good growth provides humidity of 80-90 percent. This climate is not suitable for the development of spider mites.
Along with watering and weeding the soil, it is necessary to remove weeds. Also periodically inspect each cucumber bush in order to detect and prevent the threat in time.
If a pest is detected, it is recommended to use specially designed chemicals. Collecting pests manually will not only not give positive results, but will also allow the mite to spread to neighboring bushes. When treating infected leaves, the mite will not only be unable to reproduce, but will also be completely destroyed over time. Treating the plant every two weeks will allow you to achieve high efficiency.
The phytoseiulus mite will allow you to save cucumbers in a greenhouse. This predator eats spider mites. It is enough to place a couple of leaves with this predator in the greenhouse. In just a few days your problem will be solved.

What to do

Having discovered a spider mite, you need to be prepared for a difficult and lengthy fight. Be patient. If you do everything correctly, you will definitely remain the winner in this fight. There are chemicals designed to combat this pest. However, you need to know that spider mites, like any other pest, quickly get used to toxic substances. If the product you have chosen remains ineffective for a long time, it needs to be replaced. Moreover, it is not the name of the drug that needs to be changed, but its composition and active ingredients.

A common belief is that ticks are destroyed by UV lamp, is not entirely correct. Of course, it can have a negative effect on an adult, but the larvae will remain alive. In general, the larvae have a fairly high resistance to many negative factors. This is why it is so important to find the most suitable remedy in short time.

There is an opinion that spider mites can be destroyed using traditional methods. But there is no guarantee of your success. If you decide to use folk remedies, it is better to combine them with special chemicals:

Almost all chemicals have some toxicity. That is why they must be used strictly according to the instructions, without exceeding the permissible dose.

The treatment of greenhouse plants deserves special attention. Indeed, in this case, chemicals will be sprayed into closed space. Here you just need to use the means personal protection. In addition, processing must be carried out strictly according to the instructions. Any excess of the permissible dosage of the drug can lead to harmful consequences.

As a rule, it is not recommended to use shock doses of chemicals in confined spaces. That is why it is extremely important to detect plant infection in initial stage. Most likely, processing will have to be carried out repeatedly. Drugs of moderate toxicity and low concentration are recommended here.

Today you can find many chemicals designed specifically for processing cucumbers in greenhouses and greenhouses. However, if the pest was detected in the initial stages of infection, you can first try folk remedies. For example, in greenhouses you can fight mites using peroxide, ammonia, and turpentine. Infusions of plants that are toxic to ticks are also used. Often the problem can be solved with biological products.

Before processing plants, it is necessary to remove cobwebs. Otherwise, it can prevent droplets from falling directly onto the plant. For processing in a greenhouse the following are used:

dope;
calendula;
garlic and onion peel;
dandelion.

The ground plants are poured with water, brewed and infused. Such products are applied to plants using a sprayer. It is better to carry out processing in the evening, when the sun stops burning. Otherwise, the toxins will quickly disintegrate, reducing the effectiveness of the tinctures to zero. As a rule, one treatment is not enough. Therefore, the procedure will need to be repeated one or two more times.

Treating cucumbers against spider mites with folk remedies

Of course, traditional methods of pest control can also give positive results. However, you need to know that you can only hope for them if the infection was detected at the initial stage. But this does not mean at all that they are useless when the pest has already spread to many bushes. In this case, you will have to use special chemicals, the effectiveness of which will be supplemented by folk remedies.

This is one of the most popular folk remedies. For processing it is necessary to prepare a solution. Dilute 1 tablespoon of alcohol in 10 liters of water. The resulting mixture is sprayed onto the stems and leaves of the affected plants from all sides. This treatment will not only destroy the pest, but also saturate the plant with nitrogen.

Zelenka is the same alcohol solution that can destroy pests. To treat plants, prepare a composition of 2 liters of whey, 50 grams of dissolved urea, 10 liters of water and 10 ml of brilliant green. After thorough mixing, the infected plants are sprayed with the mixture. Zelenka can protect cucumbers against many diseases:

peronosporosis;
powdery mildew;
spider mite;
root rot;
bacterial cancer;
late blight

By diluting one drop of brilliant green in a liter of water, you can treat cucumbers as a preventive measure. If you use brilliant green for pest control, do not exceed its concentration. A large amount of brilliant green in the composition can lead to leaf burns.

Other

There are other folk remedies that will help solve the problem:

Iodine is used not only to kill pests, but also for preventive purposes;
vinegar is diluted with water in a ratio of 2:8. This composition is used to treat young shoots of cucumbers;
2 tbsp. hydrogen peroxide is diluted in 1 liter of water. It is recommended to spray cucumbers 3-4 times. The break between treatments should be at least one week;
powder mustard. 60 g of mustard is mixed in 1 liter. water. After this, the composition should sit for several days;
laundry soap is used to prepare a soap solution that is used to wipe the stems and leaves of plants;
tar soap is also used for mixing with water;
tomato tops contain substances that repel pests;
Dried wormwood is used to prepare a tincture. Its toxic substances can quickly destroy spider mites.

Preventive measures

Since it is more difficult for spider mites to develop on tomatoes, it is recommended to alternate planting cucumbers with this crop annually.
Remove weeds and other debris from the garden beds promptly.
Using specially designed agricultural technology, you can leave the most optimal distance between the bushes.
Maintain high humidity in greenhouses.
Systematically inspect the plant for infection.
Maintain an interval between spraying and watering.
At the first signs of the appearance of a spider mite, the fight against it should not be postponed until later. After all, the pest will soon colonize the garden bed en masse, and it will be quite difficult to remove it.

Remember to take all preventive measures regularly. Maybe not all at once, but in stages. But all of them must be carried out sooner or later. This is the only way you can protect your harvest.

Spider mites on cucumbers - signs of infection, folk methods of control, treatment and prevention!

Good afternoon, dear readers.

In this article, you will learn about the signs of spider mite infestation. What conditions are favorable for infection? How to treat a disease using traditional, proven methods. How to treat affected bushes in greenhouses and open ground.

What are the methods for preventing the disease? And what varieties are best to plant. What rules must be followed to get good harvest. Great practical article!

Last time I told you why the ovaries on cucumbers turn yellow. Not every summer resident knows what spider mites on cucumbers are, how to deal with this pest and prevent problems from occurring. This a big problem many gardeners, with which they constantly struggle.

Sometimes the fight against spider mites takes a long time, and even a greenhouse can’t save you from it. This article will tell you how to prevent infection and get rid of the scourge.

How to recognize spider mites on cucumbers?

Small insects that live on plants and in the soil negatively affect the future harvest, spoil the root system, leaves and shoots of bushes.

The described creatures feed on the juice, infecting the green mass of cucumbers, and with the arrival of cold weather, the pests move to the lower layers of the earth.

How does it get on plants?

As a rule, insects live and actively reproduce exclusively in conditions favorable to them, including dry air and high temperature.

They overwinter in the soil, fallen leaves, manure and other secluded places near the garden, so it is difficult to protect the future harvest.

In a greenhouse, spider mites appear by getting on seedlings,
and in open ground the pest is brought by gusts of wind or contaminated fertilizers.

Signs of infection.

The following signs indicate an insect attack on plants:

light spots on the back of the leaf;
whitish cobwebs, slower bush growth;
yellowness of stems and leaves.

It is important to know that the pest causes cucumber diseases such as gray mold and disruption of photosynthesis, thereby the spider mite provokes depletion and death of plantings.

Measures to combat it should be taken immediately after harvesting - all parts of the affected plants must be collected and destroyed, otherwise next year you risk being left without vegetables at all.

Pest in the greenhouse and in the garden - fight.

It is more difficult to get rid of spider mites in a greenhouse, because all the conditions have been created here for insects to multiply and infect vegetable crops.

However, the pest does not survive at air humidity levels of more than 80%, so moistening the plantings will be a good preventative method.

So, you can get rid of the scourge by taking the following control measures:

disinfection of the greenhouse in autumn and spring;
removing the top layer of soil;
application of special fertilizers.

It is important to know that most ticks overwinter in the ground, and insects also hide near weeds.

Crop rotation.

In open ground, special attention should be paid to the problem:

By removing weeds and carefully inspecting the bushes to detect affected leaves.
Experienced gardeners also advise alternating planting cucumbers with tomatoes or cabbage in the fresh air,

It is believed that the higher the air temperature, the shorter the interval between plant treatments should be.

Administration of drugs.

Among effective drugs from the pest can be identified such as “Iskra-Bio”, “Fitoferm”, “Karbofos”.

These products should be used in the evening, when the sunlight and the chemicals do not have time to evaporate.

Land cultivation.

In greenhouses and open ground, soil cultivation is important, since pests hide and overwinter there.

Don’t be lazy in the fall after harvest and in the spring:

carefully dig up the ground,
remove fallen leaves,
remnants of weeds,
and manure from its surface,

This simple pest control measure will help significantly reduce the risk of bush infection.

Spider mites can feed on both cucumber seedlings and adult plants, so the land for planting must be cleaned and inspected.

Fertilizer application.

We must not forget about applying useful fertilizers.

Phosphorus is necessary for cucumbers to grow green mass and form ovaries, such mineral supplement must be added to the soil; it will increase productivity and strengthen plant immunity.

Strong and hardy bushes will resist pest attacks, which means cucumbers will be able to bloom and bear fruit on time.

Fighting ticks with folk remedies.

It is no secret that dangerous chemicals threaten human health and should be used only in extreme cases.

Peroxide solution.

You can get rid of spider mites at home by preparing safe and effective means.

Just 2 tablespoons of hydrogen peroxide 3%, dissolved in 1 liter of water, will help cope with the scourge.

It is useful to spray the plants with this solution 3 times every 5 days, and soon you will notice how the insects retreat and die.

Ammonia solution.

The following has a similar effect:

1 teaspoon of ammonia, diluted in the same amount of water.

The resulting liquid inhibits the development and life cycle pest

And in order to prevent further tick attacks, experienced gardeners place jars of turpentine near the affected bushes.

With the help of herbs.

Interestingly, you can even fight spider mites with the help of plants.

Calendula, dandelion, sorrel, yarrow, onion and garlic are suitable for this purpose.

Take chopped herbs or dry raw materials.
Pour boiling water over the product and leave for 1 day.
Then spray the cucumbers with the resulting liquid, it is best to do this through drip irrigation.

And after completing the work, it is useful to sprinkle the bushes with tobacco dust; this product will protect them from secondary attack by insects and will not spoil the foliage.

Soap solution.

Another proven folk method of fighting spider mites is a soap solution.

So, approximately 200 g of crushed laundry soap should be diluted in 1 bucket of warm water.
The resulting liquid must be infused, stirred and used to process cucumbers.
Treated plantings are left for several hours to get rid of insects, then the foam is washed off.

And they maintain a high level of humidity in the greenhouse, and in open ground it is recommended to cover the cucumbers with a plastic bag for 1 day.

This method is safe, and gardeners even use it to protect and treat indoor plants.

It is important to know that you should not allow soap to get on the roots, as this can harm the vegetable crop.

Strengthened mixture.

To increase the effectiveness of the product you can:

Mix 50 g of laundry soap with 500 g of fresh garlic.
Pour 3 liters of water over the products and leave the liquid in a dark place for at least 5 days.
Be sure to strain the infusion and dilute with clean water,

In addition, simple garlic juice is also suitable for spraying.

Cucumbers resistant to spider mites.

Today, breeders from all over the world are working to create new varieties of vegetables, including pest-resistant ones. Therefore, when growing cucumbers, you need to choose strong, resistant varieties.

Of course, it is not yet possible to completely protect yourself from spider mites, but it is now possible to reduce the risk of insect attacks and increase crop yields.

Hybrid "Spring"

The popular hybrid “Rodnichok” is getting better every year; it can compete with European varieties.

The fruits need sufficient moisture, however, this plant has good immunity against diseases and pests.

Variety "Murashka F1"

Good feedback The early ripening variety “Murashka F1” also deserves its name; it not only produces an excellent harvest in the greenhouse and open ground, but is also less likely to be affected by spider mites.

The fruits have an improved taste and are suitable for pickling and fresh consumption.

Hybrid "Benefit F1"

Prevention of insect damage to cucumbers.

Effective measures to combat the pest are difficult, since spider mites reproduce quickly and even develop immunity to chemicals.

And in some cases it is difficult to identify; the small insect settles on the underside of the leaf and is well camouflaged.

Preventing a tick attack is easier than dealing with the consequences of their attack.

Do not forget about the need to dig up the soil in the fall and spring after the snow melts.
It is also necessary to destroy the remains of plants, especially affected ones. Experienced summer residents advise immediately burning dried bushes.

That's all. New articles on growing plants and helping the gardener are yet to come. How do you treat this disease? I look forward to your comments.

How to fight spider mites on cucumbers in a greenhouse using folk remedies

When planting any crop in open ground or in a greenhouse, the owner wants to get an excellent harvest and tries to take all measures so that neither disease nor pests harm the plant. But not everyone succeeds in this. A spider mite that appears on cucumbers can destroy the entire crop.

A small, harmful, barely noticeable pest. If it is not destroyed in a timely manner, then not only the cucumber crop will die, but also everything that grows on the plot, greenhouse, or greenhouse.

Spider mites: what kind of “beast” is this?

It’s worth warning right away that you need to get rid of such an annoying neighbor as soon as possible. This is an insatiable creature that quickly gets used to the various chemicals that gardeners use to combat them.

Spider mites on cucumbers: how to deal with this pest? Often starts due to water or temperature regime. It is necessary to take urgent measures to combat this omnivorous pest at the slightest manifestation. After all, they appear not only in the greenhouse on cucumbers, they harm all plants in the open ground.

This pest feeds exclusively on plant sap. Losing a vital component, the plant dies. Controlling spider mites on cucumbers may be futile if it is started too late. Any remedies against spider mites on cucumbers become simply useless, the plant is dead, but the mite itself can still be destroyed.

Mites on cucumbers in a greenhouse: what can destroy them

When a spider mite finds itself in a favorable environment, it chooses the most succulent crops. A striking representative of these are cucumbers. There is sufficient juice in cucumbers not only in the fruits, but also in the leaves and stems. If you do not use some remedy or preparation, the plant will certainly die.

The complexity of the situation lies in the fact that the tick is practically not afraid of chemicals. These pests are incredibly resistant to pesticides. Moreover, they are able to adapt to any poisons.

The tick reproduces simply at lightning speed. Each individual is capable of laying about five hundred eggs every three days. 90 percent of each clutch survives. It’s scary to imagine the harm this small creature can cause.

But you shouldn’t imagine, you need to get rid of spider mites on cucumbers as soon as possible. The main thing is not to panic and not to give up if an uninvited tenant appears in the greenhouse. It's not difficult to get rid of it.

Important! Spider mites don't really like tomatoes. Therefore, planting cucumbers can be alternated with tomatoes.

With absence fruit crops, mites adapt well to weeds. Therefore, it is necessary to monitor the cleanliness of the beds and regularly clear them of weeds. Can be detrimental to ticks high humidity, which is a normal climate for any variety of cucumbers. If this occurs in a greenhouse, then it is necessary to maintain humidity within 80-85 percent.

Inspect the plants every two or three days. The slightest signs of cobwebs on the leaves may indicate the presence of a mite. Don’t forget about regular watering, loosening the soil, and spraying.

The universal Bordeaux mixture has proven itself well, which helps solve many problems both in greenhouses and in open ground. But to kill a tick, you can choose a more individual means. This:

colloidal sulfur;
fitoverm;
bitoxybacillin.

The preparations are diluted in water, after which the plant is sprayed. If mite colonies are minimal, then treatment can be carried out every ten days. If it is noticeable that it has spread over a large area, then it is advisable to treat the plants every five days.

The spider mite in nature has its worst enemy, who will happily destroy it in the greenhouse. This is a phytoseiulus, which can be forced to settle near tick habitats. The diet of this insect consists exclusively of spider mites.

Without affecting the plant, it will quickly destroy the entire colony along with the eggs. To do this, it is enough to spread several leaves with such a hunter closer to the infected plant, and already on the second day, only a cobweb may remain from the spider mite, which is not difficult to remove.

If the proposed remedies do not help, then the stage of damage is too advanced and more radical measures are required before the plant dies. These may be preparations containing acaricides. But their use will destroy the population of phytoseiulus, and open areas poses a danger to bees. Therefore, spider mites must be dealt with as early as possible.

What are acaricides

The very name of such drugs makes it clear the essence of their use. Accurate translation sounds like this:

Acari-mite:
Cide-cut.

Such preparations are used not only to save plants. They can be used to treat indoor plants and pets. But they are all toxic, so the use of any drug must comply with the instructions attached to it. Their range is quite extensive. You can imagine the most popular ones.

Aktelik. The most common drug, tested by almost all gardeners. Contains irimiphosmethyl, toxic. After spray treatment, mite colonies begin to die within five minutes. The person carrying out the processing must use personal protective equipment, a mask, and gloves.
Aktara. Contains thiamethoxam, which is effective in killing any insects.
Phytofarm. This is a biological preparation containing aversectin. It quickly affects the tick, causing paralysis instantly, and the death of the pest occurs within a few hours. The drug is slightly toxic and not dangerous to people and animals, but precautions must be observed when working with it.
Fufanon. The main component found in the composition is malathion, which, upon contact with ticks, paralyzes them and destroys them within a few hours. It has a low degree of toxicity, is not dangerous to people and animals, but can destroy beneficial insects and bees.

This is only a small part of the powerful and fast-acting drugs that are used to destroy entire colonies of poutine mites. Even if the packaging indicates that the drug is safe for humans, it is necessary to work with it carefully. Some components may cause an allergic reaction.

Wear rubber gloves and masks, which must be destroyed after use. Protection in the greenhouse, as well as in the open ground, must be carried out on time, then there will be no need to resort to such radical measures, dangerous for others.

Humanity has long been engaged in the cultivation of various crops. Therefore, there are folk remedies that have been tested for more than a century. These are products that do not pose a danger to humans and can protect future greenhouse or garden cucumber crops.

It is clear that most gardeners do not want to use heavy artillery to kill a tick. This poses a danger to humans and domestic animals. Such radical measures are dangerous for bees, without whose help it is impossible to live in the countryside.

The most important thing in this country war is the timely detection of the pest. Then you can count on folk remedies for spider mites on cucumbers.

Such difficulties may arise due to various reasons. There is a long absence of a person, or it is a greenhouse with seedlings, which cannot be visited often. In this case, it is best to foresee a possible problem in advance. Armed means protected, resistant to any pest.

Spider mites on cucumbers, how to fight with improvised means

For this purpose, a variety of means are used that are available in every home. It could be:

soap;
alcohol;
garlic;
herbs and infusions from them;
rosemary extract.

An aqueous solution of laundry soap is used not only for cucumbers. Such a liquid can increase the resistance of roses, indoor plants, and many vegetable crops. It is absolutely safe for humans. The same can be said about other folk remedies that are no less effective.

Home » Gardening and floriculture » Plant diseases » How to deal with spider mites on cucumbers

The Putin mite is a serious pest of agricultural crops. With a size of less than 1 mm, it can cause serious damage to the farm.

At first, mites form small clusters, but over time they multiply and occupy the entire greenhouse, greenhouse or garden bed. As they multiply, they form a web in which young mites develop.

The ideal place for the development of ticks is greenhouses and hotbeds, since temperatures from 20 to 30 degrees and moderate humidity promote the reproduction of these arachnids.

Mites often appear on cucumbers grown in open ground. Ticks reproduce very quickly: the female lays 400 eggs up to 20 times a year.

Signs of ticks

Dots on the undersides of leaves and yellowing;

Slow plant growth;
Discolored areas of leaves;

When there are a large number of mites, they become visible on plants with the naked eye.

Spraying is done every week for a month. After which a break of 18-20 days is taken. Then the procedures are repeated.

fitoverm, 10 ml of which is diluted in 10 liters of water. This drug effectively kills ticks. The downside is that it is addictive, so it cannot be used repeatedly;

Iskra-bio, akarin, spraying with these drugs is also quite effective. The advantages of these products, including Fitoverma, are their safety, the plants can be eaten after two days from the time of treatment;

colloidal sulfur, 80 g per 10 l;

bitoxybacillin and bicol, 100 g per 10 l. Plants are sprayed during the growing season with a break of 10-14 days;

Actellik is available in the form of ampoules, the contents of which are diluted in 1 liter of water. The solution is poured into a spray bottle, with which the plants are sprayed;

Plant Pin and etisso are sticks that are inserted into the soil next to the cucumbers. The substance acts during watering, during which it dissolves, enters the soil and is absorbed by plants. These drugs help effectively fight ticks on early stages check-in. This stick protects for 1.5 months;

Spraying is carried out 3 times during the growing season every 8-9 days. And at temperatures above 30 degrees, every 3-5 days.

Treatment is carried out in the morning or evening, when it is cool, so that toxic drugs do not evaporate.

When using any chemical, you must strictly follow the instructions and remember that improper use is dangerous to human health and affects the quality of the crop.

The last treatment should be no later than 2-3 weeks before harvest. This time is enough for the toxic substances to be completely released from the cucumbers. Otherwise, you can get poisoned by the harvest.

Therefore, it is worth resorting to chemical treatment methods as a last resort, when other methods do not help.

An average of 7-8 individuals per 1 m2 are released into pest outbreaks. In areas with a high density of up to 30-50 individuals per 1m2. 3-4 weeks after planting, 10-15 individuals per 1 m2 are released. And then, as the leaf surface grows, 3-4 times every 12-15 days, each time increasing the norm by 10-20 individuals per 1 m2.

Plants that repel ticks are planted among cucumbers: calendula, parsley, garlic, mint, onion, wormwood, etc.

Agrotechnical

Alternate planting of cucumbers with tomatoes, since mites do not develop on tomatoes. That is, if too many mites have developed on cucumbers in a garden or greenhouse and you cannot get rid of them, tomatoes should be planted in this place next year. Since mites do not live on tomatoes, they will completely disappear within a season;
Timely weeding and proper care of plants: watering, fertilizing, loosening the soil, removing old leaves, etc.;
Plant with a significant distance between plants to make it difficult for ticks to move. It is better to alternate beds with cucumbers with beds on which other crops will grow. In this case, if ticks appear in one of the beds, the others will not be harmed. If they are located close together, all cucumbers can be infected in a short time;

Cleaning the greenhouse or garden in the fall from all garbage, rags, and plant remains that must be burned. In addition, a greenhouse or greenhouse can be disinfected, for example, using FAS or Climate sulfur bombs;
Deep digging of the soil, preferably in the autumn;
Creating high humidity (80% and above), which is considered optimal for plants, but unfavorable for mites;
Inspect plants for mites.

Note.

Spider mites easily get used to and adapt to almost all poisons.

The difficulty of controlling ticks is also due to the fact that:

They are not immediately noticeable;
Females lay eggs within 4 days of emergence;
Ticks are able to adapt to chemicals;
High reproduction rate.

Spider mites on cucumbers: we remove them once and for all

How many pests encroach on the gardener’s cucumber harvest, it takes an eye and an eye to collect the juicy fruits. One of the main enemies of cucumber plantings is not visible to the ordinary eye; it can only be seen through a magnifying glass, but it can cause a lot of trouble. This is a spider mite that feeds on the juice of cucumber leaves. Foliage damaged by insects turns yellow, dries out and falls off.

How to recognize a spider mite

The spider mite is microscopic in size and impossible to notice. As a rule, only traces of insect activity are visible. When there is a massive infestation of pests, the leaves of the vegetable are damaged. The mite multiplies quickly, capturing more and more leaf blades. Leaves deprived of juice change green color on lemon, fade, and then fall off. In a couple of weeks, the mite is able to leave only stems in the garden, and the soil will be strewn with withered leaves.

To recognize the pest, you need to turn the sheet back. There will be visible cobwebs and black dots on it - traces of the pest’s activity. In case of severe damage, the petioles and internodes will be shrouded in cobwebs.

If you look at the affected leaves through a magnifying glass, you can see the pest itself; the insects look like microscopic spiders.

Spider mites appear mainly in greenhouses. The most comfortable atmosphere for him is a closed, poorly ventilated space with dry hot air. It turns out that hotbeds and greenhouses are a real haven for him.

How to create unfavorable conditions for spider mites

The spider mite is quite tenacious, and if the conditions in which cucumbers grow are not changed, it will appear on the plants again and again, even with repeated treatments, which, by the way, also cannot be carried out for the entire season.

Treatments against the pest are completed two weeks before harvesting.

It is necessary to take into account that cucumbers bear fruit all season, so it turns out that they can be treated with ready-made means only until the first ten days of June, the rest of the time you need to use folk remedies, or even better, create conditions that are uncomfortable for the pest to live.

Basically, the mite settles in greenhouses; its presence in the beds is a rare case. In the garden, as additional moisture, there are natural rains and precipitation, which the mite does not like at all.

In the greenhouses there is complete calm, and there is no precipitation except for watering, which suits the spider mite.

To get rid of pests, spraying is carried out two weeks after planting cucumber seedlings or sowing in the ground. Not only plants are treated, but also walls, ground and roof.

Spraying is carried out even if the pests are clearly invisible. This will help prevent massive leaf damage in the future.

In addition to spraying, barrels of water are placed in greenhouses, additional containers of water are placed, and plants are sprayed on the leaves.

To prevent the appearance of spider mites, I inspect the plants that sit in the corners of the greenhouse. They are the first to be affected by the pest.

How to get rid of spider mites on cucumbers: folk and ready-made remedies

What to do if, despite all the measures, the spider mite still becomes an uninvited guest on cucumbers?

For pests, ready-made remedies are used, such as:

Karbofos, actara or actellik;
Flumite has perhaps the longest protection after application, it lasts up to 6 weeks;
Envidor can also be used in wet weather, it is resistant to washing off, and is excellent for treating open ground cucumbers;
Tickweed kills pests within 7 to 10 hours.

Do not forget to use gloves and a respirator during processing, and then thoroughly wash your hands and face with soap and change clothes.

As an alternative ready-made means I also use traditional solutions for spraying cucumbers against spider mites.

In the fight against spider mites, it is necessary to use ready-made and traditional spraying solutions together. Chemical-based products are applicable only before the plants bloom; after that, biological solutions are used to prevent the fruits from absorbing chemical elements.

I prepare the following environmental solutions for spider mites:

An indispensable and accessible solution is garlic: 50 grams of crushed cloves, pour half a liter of water, stir thoroughly, seal hermetically and leave to infuse. After a day, I filter it, dilute it in a bucket of water and spray the cucumbers. I also cultivate the soil under them, as well as the walls;
A solution with slices of hot pepper is also good. You can use fresh or dried. I prepare it in the same proportions as the garlic solution;
If I have tobacco dust on hand, I spray it on the leaves and first pour water over them;
A solution of 3% hydrogen peroxide also copes well with pests; I dilute one spoonful in a liter of water and spray it.

All biological treatments must be repeated after 3-5 days to destroy new generations of pests emerging from eggs.

After treatments, I close the greenhouse so that the drug acts more effectively and the pests do not have access to fresh air. I prefer to carry out such treatments in cloudy weather and in the morning; on such days I keep the greenhouse completely closed.

Before starting processing, fallen leaves are collected and burned. They contain some pests and oviposition.

How to increase humidity in a greenhouse

To protect cucumbers from spider mites, I take care to increase the humidity in the greenhouse immediately after planting. To do this, I place basins, buckets, deep bowls between the plants and fill them with water. This method performs several functions at once: it increases the humidity in the greenhouse, which is what cucumbers like, creates uncomfortable conditions for spider mites, and increases the temperature in the greenhouse.

I make sure to place barrels of water in the corners of the greenhouse; they also humidify the air and give me warm water for watering the cucumbers, which is very convenient.

If there is a tile in the greenhouse, it is good to water it with water on hot days. You can lay linoleum in between, bending its edges in the form of a trough and fill it with water in the heat. You can place linoleum troughs in the boundary, but then you need to walk on them with caution, or you can place them between plants. To prevent the edges of the linoleum from moving apart, I fasten them together with a construction stapler.
