Narc wa fight with spider mites. How to deal with spider mites - effective methods of destruction

The spider mite belongs to the class of arachnids. This must be taken into account when choosing a pest control agent; preparations for the destruction of insects do not work on it.

It lives for about a month, the female can lay unfertilized eggs, from which new female ticks are hatched in 3-5 days, capable of laying eggs on their own in a week (up to hundreds of pieces). In a short time, the population can increase hundreds of times. The spider mite hibernates in the ground or in the crevices of greenhouses and greenhouses, eggs are waiting favorable conditions do not lose viability for several years.

Only emerging into the world, the larva spider mite, digs into the leaf of a suitable plant from the underside, and begins to suck out the juice. The "menu" of the spider mite includes about 200 varieties of plants. The appearance of a pest can be detected by noticing yellow drying points and spots on the surface of the leaves. Looking at the underside of the leaf, you can see a thin web and small greenish or red creatures - this is the spider mite. With a large number of pests, plant leaves quickly dry out, growth slows down and is inhibited. In addition, spider mites can carry infections that are dangerous for plants (gray rot, viruses). If urgent action is not taken, you can lose the entire plantation, the tick spreads very quickly.

Ticks are especially rampant in protected ground. In a greenhouse, with its elevated air temperature and many places where you can comfortably overwinter, the tick feels great. Therefore, in addition to the usual means for the destruction of the pest, autumn washing and disinfection of the greenhouse is required.

Preparations for the fight against spider mites

Cucumbers, eggplants, tomatoes, peppers, beans are especially often affected by spider mites. It causes considerable damage to flowers, especially asters and roses. Apple trees, cherries, pears, mulberries, currants, strawberries and gooseberries also suffer from the pest.

When choosing a drug to fight a tick, you need to remember that it does not belong to insects, and it makes no sense to use insecticides.

Acaricides are used against spider mites: Omite, Flumite, Demitan, Apollo, Bitoxibacillin (10 g per 1 liter of water), Borneo. Insectoacaricides will also be effective: Fufanon, Oberon, Aktofit, Kleschevit, Fitoverm (1 ml per 1 liter of water), Karate, Agravertin, Akarin (2 ml per 1 liter of water), Vertimek.

The preparations are diluted in strict accordance with the attached instructions.

Important! The treatment with chemicals is carried out, observing all precautions: when spraying on the foliage, it is necessary to wear a respirator, goggles and gloves. After finishing work, send the work clothes to the laundry, wash your face and hands with soap and water. Smoking or eating while working is prohibited!

Due to the short development cycle of the mite and the ineffectiveness of the drug on pest eggs, several treatments are carried out on plants. Usually, 3 - 5 sprays are enough, with an interval of 4 - 7 days. The higher the air temperature, the shorter the interval between sprayings.

The tick has the ability to get used to and adapt to toxic substances, so the drugs need to be changed regularly. You need to focus on the change of the active substance, carefully reading the composition of the drug on the package.

The disadvantage of the use of chemicals can be considered their toxicity to pets and people.

Some substances (based on phosphorus) are not allowed to be used indoors. Many products cannot be sprayed on fruit-bearing plants. The use of such strong agents is justified in case of severe damage to plants and a large area of plantings.

Folk ways of fighting

The spider mite does not tolerate high humidity. With a small number of pests and to prevent its occurrence, it is useful to wash the plants with a stream of cool water. Barrels and buckets of water are placed in greenhouses to increase air humidity (at 80% - 85% humidity, the tick dies). These measures are quite effective, provided that high humidity is not harmful to plants. This method works well for cucumbers. To increase the humidity in open field, in addition to the shower, the bushes can be wrapped with pieces of film or placed wide containers of water under them.

The timely (preferably daily) collection of the affected foliage and its burning prevents the spread of the pest.

In the greenhouse, you can arrange open jars with turpentine or ammonia. Vapors of these substances will poison the tick. Less caustic, but also good remedy- Chopped garlic and onion.

Sowing marigold among vegetables will help scare the pest from the beds.

It is possible to apply an effective biological method of dealing with spider mites in a greenhouse - to launch a colony of predators that feed on them. These are predatory mites Ambliseius and Fitoseylus. They are not dangerous to plants and will die when they deal with the pest. You can buy them in large garden nurseries.

Washing the foliage with soapy water will help get rid of the pest. To prepare it, they take simple household or tar soap, you can buy special green soap at the garden store. Soap is dissolved in a bucket of water, and the affected plant is washed abundantly.

Important! The soapy solution, drying up, forms a film on the leaves, which prevents the plant from breathing. Therefore, a couple of days after the treatment with soap, the bush should be washed with plain water.

It is easy to prepare an infusion of onions and garlic for spraying the affected plants. 200 g of garlic or onion are crushed and infused in a liter of water.

A few hours is enough for an onion. Garlic is insisted for a day, then the solution is diluted with water 3-4 times. The resulting mixture copes well with the spider mite, with its small number.

Herbal infusions for spraying plants against ticks:

dandelion infusion - 0.5 kg of greens insist for several hours in a bucket of water;
calendula - 100 g of chopped herbs per 1 liter of water, infused for 4 - 5 days;
celandine - a teaspoon of grass, pour a glass of boiling water and cool;
yarrow - brew 100 g of dry raw materials with a liter of boiling water, dilute with 5 liters of water.

Preventive measures

It is necessary to regularly inspect the plants in order to notice the pest as early as possible and take action.
In the fall, digging the soil and filling the soil with phosphate fertilizers will help to destroy the pest hiding in the ground.
Greenhouses and hotbeds are washed in autumn, the top layer of soil is changed, fumigated with a sulfur checker, and the frame is whitewashed with lime.

Numerous plant pests do not cease to keep gardeners in constant tension, forcing them to look for new ways to fight for crops in the garden or on suburban area. They are no exception, and, with particular activity, striking cucumber plantings.

If for some reason the spider mites are not destroyed, with full confidence we can expect them for the next season: they overwinter there, in the greenhouse, in the upper layers of the soil, in the corners, in manure, under unharvested foliage of plants.

Signs of infection and damage

The spider mite is a small insect 0.2 - 0.5 cm long, without antennae and wings, has 4 pairs of legs. Color - pale green or greenish with a yellow tint. Males are slightly smaller than females and have a more elongated body shape.

On spoiled cucumber plantings, as a result of the vital activity of a tick, the following signs appear:

light, almost white dots (with a large lesion - extensive spots) on reverse side leaves;
the plant looks sick, entangled in a web, along which ticks move;
slow growth;
leaves gradually turn yellow.

The spider mite is also capable of provoking the development of gray rot, which affects the entire aerial part of the plant and inevitably leads to its death.

If the pest is not stopped, harvesting is out of the question. There will simply be nothing to collect.

How to fight

Folk methods

The old, well-known methods for the destruction of plant pests for the most part involve the use of improvised means that are always safe for humans and will not damage seedlings due to lack of chemical components. Here you can use ordinary products that are always available at home, or simple pharmacy preparations.

Hydrogen peroxide. You will need 3% peroxide (2 tablespoons) and 1 liter of water. Spraying is carried out 3-4 times with a break of 1 week at 20-degree temperature or 3 days at 30C. Such treatment can destroy the entire family of spider mites.
Vinegar. For 8 liters of water, 2 tbsp. l. essences, everything is mixed. Spray the seedlings of cucumbers generously with this tool. It also helps well against cruciferous fleas, aphids, codling moths.
Sulfur-tar soap. Dissolve 100 g of soap in a 10-liter bucket, spray the flowers of plants 2-3 times a week. You can also prepare such a solution: 40 g of soap per liter of water.
Ammonia. Spray the plants in the same way as the hydrogen peroxide recipe. To do this, prepare the following mixture: 1 tablespoon of ammonia per 10 liters of water. It is useful to process the leaves on both sides, not only to remove mites, but also to saturate the plant with nitrogen.
Dry (powdered) mustard. In 1 liter of water, brew 60 g of powder, let it brew for 3 days in a tightly sealed container. Dilute the resulting tincture with 3 liters of water and spray cucumbers with it. The spider mite is very afraid of the smell of mustard.
Iodine. It helps to fight, including for plants that have already undergone a disease. Treatment is carried out by spraying cucumber lashes on both sides with a solution of 10 parts of water, 1 part of milk and 7-10 drops of iodine.
Laundry soap will also help against these insects. Wash the plants with warm soapy water. The remaining foam can not be removed. You can also spray cucumbers with a soap solution. The method helps only with a small number of ticks.

Very effective in the fight against spider mites is the drug Fitoverm, which is no longer quite a popular method, but also not a chemical one. This is a kind of biological insecticide, created on the basis of the vital activity of soil microorganisms. The tool does not contain chemicals, and therefore is absolutely harmless to humans. Fruits can be safely eaten after 2-3 days after processing. Fitoverm perfectly helps to get rid of both spider mites and many other garden pests, without causing them to become addictive. Does not cause burns in plants after application.

Fitoverm action time:

The solution must be prepared in accordance with the instructions on the package, it must be used immediately (do not store). Usually, only 2 treatments (1 per week) are enough to get the result. If it is not possible to get the drug, it can be replaced with 80 g of sulfur or 100 g of bitoxibacillin.

Chemical methods

The last treatment with chemicals is prohibited less than 2-3 weeks before fruiting. A more precise interval between spraying and collection is indicated on the packaging of each particular insecticide, as well as its dosage and frequency of application.

Prevention

Preventing a problem is always much easier than getting rid of it, so simple preventive rules will always help to avoid painful pest control or crop loss:

carry out timely weeding (mites can also live on weeds in a greenhouse);
plant among cucumbers, especially in the corners of the greenhouse, “unloved” tick plants (dill, etc.);
immediately remove and burn the affected parts of plants;
alternate planting cucumbers and tomatoes in the same greenhouse annually;
follow all the rules of care (watering, weeding, loosening the soil, top dressing, removing leaves, preventive treatments with folk remedies, etc.);
after harvesting, completely remove the remains of plants and destroy them;
inspect plants in a timely manner during their growth and development;
maintain humidity in greenhouses;
dig up the ground after harvesting;
observe the distance between the beds or plant cucumbers alternately with other plants (ticks do not like to move far).

It should be noted that these measures will help to get rid of ticks not only on cucumbers, but also on such plants, in many respects similar, as tomatoes, eggplants, peppers, etc.

Care of plants in the house, work on personal plot for lovers of the green world - hard work, but not without pleasure. Especially when you see the results of your work. It's a shame when the plant suddenly begins to turn yellow, covered with nasty dots, or even completely fades. A thin web appears at the top or along the entire height. We sympathize - you got a spider mite. Look for effective remedy from spider mites, and immediately, otherwise the crop will be lost! AT room conditions ticks are very active and quickly move from leaf to leaf, from one plant to another. Delay in action threatens to infect everyone

Meet the spider mite

It is almost impossible to see a small insect, ranging in size from 0.3 to 0.5 mm, with the naked eye, and even more so its eggs. Rather, the damage caused by it is immediately visible. The spider mite, despite the name, is not related to the category of mites. It's not an insect, it's an arachnid. This information is important to determine active remedy from spider mites.

The color of the insects varies from green to brown-brown or red in winter time. The body is rounded and covered with bristles. Spider mites hide on the underside of plants, and it is difficult to notice them because of their tiny size. They begin to look for a remedy for spider mites when the leaves are already covered with brown or white dots. It is very difficult to practically destroy this pest completely and forever. Ticks have greater vitality and, when adverse conditions occur, they cease to spoil the plant, but do not die. They can endure a long period of starvation by hibernating in anticipation of better times.

Optimal living conditions

The unique adaptability to the habitat and weather conditions allows the spider mite to live throughout the globe, except for Antarctica. Optimal conditions: temperature 20 - 30 degrees Celsius, air humidity - 35-55%. The active stage of activity and reproduction of the pest begins at outdoors from June. In early August, ticks begin to hibernate. Exactly active period favorable for spraying plants. It is worth using folk remedies for spider mites. Very high summer temperatures, high humidity, the onset of cold weather stop the active phase of activity, the insects hibernate, hide in the soil, in the crevices of buildings, under the remains of plants.

They crawl under the baseboards, on the ceiling, in the cracks in the window sills. It is difficult to use a remedy for spider mites during this period, since the spiders themselves are not visible, and their places of activity are also - they sleep and do not eat. Visually it seems that everything is in order, but the tick is just waiting for a favorable period.

Tick larvae and adults are carried by humans, animals, on the web. Yes, they crawl fast. AT good conditions egg clutches remain viable for up to 5 years.

Severity of damage

The tiny size is offset by the numbers. Spider mites live in colonies, they can give from 12 to 20 generations per year. And everyone, starting with the larvae, eats much larger than their size. Larvae and adults feed on plant sap, which is obtained by piercing a leaf. Numerous bites are those very small white dots. The affected leaf loses chlorophyll, the process of photosynthesis is disrupted. In addition, due to the destruction of the shell, the cell loses moisture, the sheet begins to dry. Dead cells merge into one yellow spot, then the stem, flowers, top are damaged - and the plant dies.

In parallel with the main harm, spider mites are carriers of various harmful bacteria and pathogens. It is more effective to use a spider mite remedy at the beginning of an infection. A plant that is already covered with cobwebs is too late and difficult to save. In addition to the main harm, ticks are carriers of various viruses and harmful bacteria, which also cause side diseases.

Whether in the garden, in the garden ...

Methods of dealing with this scourge are not limited to the use of chemicals. Folk remedies for spider mites, physical destruction and biological intervention are also used. The spider mite in our strip has many varieties, but some of them are especially dangerous for the garden. You need to know this in order to determine the best spider mite remedy for a particular group of plants, and apply it at the most appropriate time.

The problem of some indoor views that spray treatment is not suitable for them. And how to deal with spider mites - folk remedies or insecticides in this case? There is a way out: tampons soaked in a prepared remedy from onion or garlic, a decoction of herbs are placed in pots with affected plants. The plant is covered with a plastic bag for several days to increase the concentration of fumes.

If this misfortune started up in the apartment, disinfect the entire window sill, preventive treatment healthy plants. In some cases, it may be necessary to sacrifice one, the most diseased flower, in order to save the rest. Ticks spread very quickly and hide well when adverse conditions occur.

The fight is physical

This concept means, first of all, the creation of favorable conditions for the development of plants: watering, destruction of weeds. For indoor plants, the temperature of the content is of great importance.

The first single affected plants must be removed immediately. Destroy torn out damaged sheets or shoots, do not just leave them on the ground - this is a breeding ground for the next generations of the pest.

Biological impact

To combat the tick, biological preparations have been created: Akarin, Bitoxibacillin, Fitoverm. How to apply them correctly?

"Akarin" is diluted in a proportion of 2 ml of the drug per liter of water.
"Bitoxibacillin" - 80-100 g per 10 liters of water. The disadvantage of this drug is that it can cause allergies when in contact with treated plants.

Both solutions are used throughout the growing season every 15-17 days.

"Fitoverm" is diluted in the amount of 10 ml per 10 liters of water. Processing is carried out every 7-10 or 14-20 days. The treatment period depends on the age and size of the plant.

Another common drawback of biological agents is that they act exclusively on adults. Eggs and larvae are not affected. The processing period depends on this: for each generation - a new portion.

The pesticides clofentezin and flufenzin belong to the group of hormonal pesticides. They do not destroy all individuals at once, but sterilize the uterus. The effect of their use is long-term, but becomes noticeable after a few days. Some individuals die out, while others do not appear. If you need to destroy the tick urgently, you can mix this drug with any of the biological products.

Advantages and disadvantages of "chemistry"

What you need to know about the use of chemical industry preparations in the fight against spider mites?

Fighting spider mites with folk remedies

Methods, proven by folk experience, have an effect no worse than industrial preparations. In any case, they will not bring harm to either man or animal. Ingredients for solutions - the simplest and most affordable. Not only houseplants, but also the inhabitants of the beds, especially cucumbers, are subject to processing with folk remedies.

At the first sign of illness, take a cold shower daily for the plant. This is suitable for those species that do not mind such a procedure.
You can use either dishwashing detergent - wash the leaves, stems, pot, window sill well.
Grind approximately 150 g of peeled garlic in any way, pour 1 liter of water and leave for 5-7 hours. Dilute the resulting concentrate in the proportion of 5 ml / 1 l of water, use for plant treatment.
Like garlic, onion infusion is prepared, only it is used without dilution. Garlic cloves, onion slices can be put in a pot if the houseplant does not like spraying. Cover the pot with a plastic bag.
An infusion is prepared from the roots of dandelion officinalis: 20 g of roots per 1 liter of water. Take warm water. You can apply after a couple of hours.
It is possible to treat infected places of hard-leaved plants with a swab dipped in medical alcohol. This must be done carefully and quickly so as not to burn the leaves.

Cyclamen. Boil several tubers of this plant for 40 minutes. A day later, the broth is ready for use.
yarrow. Pour a kilogram of dried grass with a bucket of boiling water. After 3-4 days, add 3 tbsp. spoons of grated laundry soap.
Tar soap. Proportion: 10 g per liter of water.
Turpentine. A jar of turpentine is placed near the affected houseplant and cover them together plastic bag for a few hours.

Prevention

On the beds:

Timely destruction of weeds in the beds and around greenhouses, greenhouses.
Ensure adequate watering.
It is good to fertilize plants - they have greater viability against diseases and infection.
Clean the garden in the fall, dig deep into the ground.

Indoors:

Plants must be kept in optimal conditions: excessive dryness, as well as excessive moisture, is a favorable environment for spider mites.
On broad-leaved plants, dust regularly with a damp, clean cloth, periodically pamper the indoor garden with shower rain (except for those who are harmful).
Withered flowers, dried leaves, remove in time. This is not only the prevention of diseases, but also a way to extend the flowering period.

There is a good remedy for preventing the appearance of spider mites - a few drops of neem tree oil added to the water for spraying.
All medical folk methods, aimed at the destruction of the pest, in smaller doses can be used for preventive treatment. If you don’t want to lose your favorite home plants or your cucumber crop, treat them occasionally with an infusion that is harmless to people.

Getting rid of spider mites is quite difficult. After all, it is not always possible to notice a small, 0.2 to 1 mm in size, brown or greenish-gray color insect with the naked eye, not to mention its eggs. But the size of the damage caused by the pest is quite impressive, since the spider mite feeds on the cell sap of plants. The enzyme secreted from the salivary gland destroys the chloroplasts of plant cells. Why the leaves begin to turn yellow, dry out and eventually fall off. As a result, plants lag behind in growth, and sometimes even die.

On a note!
During her short life, and the red spider mite lives for about 45 days, the female lays more than one hundred eggs. Of which, after a maximum of 5 days, young individuals are born. This fact should be taken into account, timing it to the period of pest persecution.

How to get rid of the Putin tick

The fight against spider mites involves the use of chemicals and folk remedies. However, before applying them, it is necessary to carry out preparatory measures.

Such control measures should be carried out in relation to all plants in the house and even to those on which symptoms of infection were not found. After all, partial destruction of pests will not give a full result.

Wintering spider mites are disposed of by fumigation, metal constructions burned with a blowtorch.

Chemical preparations for spider mites

Fitoverm

How to use:

To prepare a working solution, the contents of the ampoule (2 ml) must be mixed with water (1 l).
The resulting composition is used for spraying plants indoors and outdoors.

The death of spider mites occurs within 6-8 hours from the moment of treatment. The residual effect of the product lasts up to 3 weeks.

Actellik

The disadvantages of the tool include the development of acquired group resistance to the composition, which is developed with systematic use. The working solution is prepared at the rate of 2 ml of poison per 2 liters of water, which is quite enough to treat an area of 10 square meters. m. The protective effect of the composition lasts up to 12 days from the date of processing. A 2 ml ampoule costs about 35 rubles.

Karbofos

Another insecticide and acaricidal agent designed to combat spider mites, codling moths, on horticultural and berry and vegetable crops. Malathion acts as an active component, the amount of which is 50% of the total volume. Thanks to high concentration The toxin chemical has a quick effect on horticultural pests.

On a note!
Spraying with Karbofos in the garden is carried out in sunny calm weather and preferably in the morning or evening hours. The dosage is determined using the instructions, taking into account the area of treatment, the type of plant and the degree of its damage:
for berry bushes, the solution is prepared at the rate of 75 g of poison per bucket of water;
for flower and ornamental shrubs 60 g of the product per 8 liters of water, the same proportions are used to combat spider mites on trees (cherries, sweet cherries, plums);
for the processing of peaches, apricots and nectarines, 10 liters of solution are needed;
citrus is processed at the rate of 5 liters per tree, and the last processing should be carried out no later than 50 days before harvest.

The period of protective action of Karbofos is 10-15 days, the speed of action of the drug is 3-4 hours. The price of a bottle of 30 g is around 30-40 rubles.
I prefer the old time-tested preparations, so I have been using it for more than one season. I recommend.
Nikita, Kislovodsk

When spraying with insectoacaricidal solutions, it is necessary to use products personal protection and follow basic safety precautions.

A good effect in the fight against spider mites is also given by the preparations of the following brands: Apollo, Karate, Neoron, Sunmite, Fufanon, Talstar and others.
Recipes from the people
Despite the effectiveness of chemicals, many gardeners and summer residents prefer to use folk remedies for spider mites, the main advantages of which are safety and availability.
Decoctions and infusions
Herbal decoctions and infusions are widely used in pest control.
An effective effect in the fight against spider mites is given by a soap solution (20 g of soap per 1 liter of water). It is better to use ordinary laundry or green soap to prepare the solution. It is necessary to wash the leaves on both sides with a napkin soaked in soapy water, preventing the composition from getting on the roots of the plant.
For spraying flowers and garden plants, you can also use sulfur tar soap (100 g of soap per 10 liters of water). The procedure is carried out 2-3 times a week.
I believe that poison for processing garden crops is not the best option. I use periodically soap and garlic solution. On the early stages nothing better is needed to infect plants.
Vladislav, St. Petersburg

Hydrogen peroxide and potassium permanganate
To combat spider mites at home, use a solution of hydrogen peroxide, which is prepared at the rate of 2 tbsp. l. (3%) funds for 1 liter of water. Spraying is carried out once a week for a month, which allows you to destroy the entire harmful family over time. For tillage, a weak solution of potassium permanganate is used.
Ammonia
Ammonia has similar properties. The solution is prepared in the ratio of 1 tbsp. l. for 10 liters of water. Leaves are treated with the resulting composition on both sides, which will not only remove ticks, but also saturate the plant with nitrogen.
Alina, Smolensk

To prevent the spread of pests on indoor flowers or seedlings, their regular inspection and compliance with the rules for caring for them will help: regular watering, timely weeding and feeding plants, as well as the use of folk remedies for prevention.
