Many farmers lose large amounts of crops due to pest infestations. Tomatoes are a garden crop that is most often attacked by various pests. Often the vegetable is grown in greenhouse conditions for sale. Of particular danger is the whitefly on tomatoes in the greenhouse. If tough measures are not taken in time to destroy it, the insect can cause irreparable harm to the crop. What are the methods in the fight against "unexpected" guests?

  • How to identify the symptoms of pest damage?

    Whitefly on tomatoes in a greenhouse is a fairly common occurrence. The insect breeds quickly in warm, humid conditions, and a greenhouse is the perfect place for this. If measures are not taken in time, it may appear on cucumbers, herbs and other crops growing nearby. The fight against whiteflies on tomatoes in a greenhouse is particularly difficult due to the high adaptability of adults to different kind processing. The danger to the normal development and fertility of the plant is borne not only by adults, but also by larvae and their metabolic products. Manifestations of pest damage:

    • white spotting in the form of dots;
    • atrophy of some parts of the stem, leafy part, twisting of the leaves;
    • larvae at the bottom of the leaves;
    • mosaic yellow pattern on the edges of the leaves;
    • fruit atrophy.

    All these signs indicate that you need to intervene immediately, otherwise the entire crop planted in the greenhouse may die. The waste products of whitefly larvae are fertile ground for the reproduction of all kinds of infections and many strains of the fungus. Any disease in combination with the invasion of pests will be impossible to cure, then the entire crop will have to be destroyed.

    Biological methods for eliminating moths

    The whitefly in a greenhouse on tomatoes feels at ease. Warm, humid conditions favor its rapid reproduction. To prevent the complete destruction of the tomato crop, you need to perform the following actions before proceeding with its removal:

    • plants need to be separated from each other so that they are at a distance of 5-10 cm;
    • equip the greenhouse with good ventilation;
    • add all kinds of strengthening agents to the water for watering plants;
    • do not destroy insects such as ladybugs and lacewings - these are inveterate enemies of the whitefly;
    • observe the humidity regime.

    Insects such as the lacewing lay their eggs directly into the pupae of the harmful moth. When the first hatch, they begin to feed on whitefly larvae. As a result of this, the offspring of the whitefly dies and it remains only to get rid of the adult offspring, which will be very easy to do after the death of the pupae.

    To prevent the appearance or get rid of pests that have already appeared, you can treat the seedlings with special preparations. It is recommended to put a small amount of chicken manure in the wells before sowing, this will help strengthen the immunity of the tomato. In order for the soil to promote plant growth, and not whitefly reproduction, it must be constantly weeded, rid of weeds and dried.

    other methods

    You can remove the whitefly by catching with special glue-based traps. Devices for catching whiteflies can be made independently from small wooden planks. They should be treated with rosin with the addition of honey or vaseline oil. The main thing is to paint the fixtures yellow because insects are attracted to this color. At the top of the bush, you need to pull the twine with a homemade trap. After that, you need to shake the plants, when some of the pests are on the bait, it must be destroyed and a new one built.

    If the whitefly on tomatoes in the greenhouse has appeared recently, and its number is relatively small, you can collect the moths by hand, and then treat the leaves and stems with soapy water to wash off their waste products and prevent infection infectious diseases. Subsequently, it is recommended to regularly spray with garlic infusion. In autumn, it is recommended to remove all remaining vegetation, and disinfect the soil that will be used for planting next year.

    The larva of the whitefly settles in top layer soil. After harvesting the tops, you need to set fire to smoke bombs, and then collect the entire upper ball of the earth. If all the above methods of control have failed, you will have to resort to the use of fungicides. Chemicals will help get rid of the whitefly for a long time, only they have a lot of disadvantages. The first and main one is the chemical composition.

    How and with what they fumigate a greenhouse

    The use of smoke bombs should be discussed in more detail. After each harvest, the greenhouse should be treated. Ideally, fumigation should be done twice a year. There are such means for fumigation:

    • smoke bomb;
    • sulfur candle;
    • tobacco bowl.

    Any kind of checkers are considered harmless to plants. It is best to fumigate in spring and early autumn. Before carrying out the procedure, seedlings should be taken out in separate room or to the street. If there is no desire to do this, you can use fumigation agents with the addition of a special preparation. As a result of such procedures, it is possible to get rid of not only adults, but also larvae with pupae.

    A sulfur candle releases sulfur into the atmosphere, the vapors of which can have Negative influence on plants and humans. Before using it, you need to carefully study the instructions for the drug. After fumigation, after 48 hours, it is necessary to thoroughly ventilate the greenhouse.

    Chemical substances

    To completely destroy and forget about the whitefly on tomatoes and cucumbers for a long time, universal insecticidal agents are used. Many farmers are reluctant to use them because chemical composition, but when nothing else helps, and the harvest needs to be saved, people are ready to go to extreme measures. With the correct use of insecticides and compliance with all the safety rules described in the instructions, you can not be afraid for your health.

    Mankind has been working on the earth for many years and trying to fight various pests. Progress does not stand still and today on store shelves you can choose any fungicide for treating plants. The most popular whitefly killers are listed below.

    1. Verticillin J.
    2. Confidor.
    3. Actellik.
    4. Pegasus.
    5. Rovikurt.
    6. Fufanon.

    In addition to chemicals for treatment during infection, there are many systemic preparations that are used when planting seeds. In order to prevent the appearance of whiteflies on tomatoes and other crops in a greenhouse, Biotlin is used. Spraying is recommended at the stage of active vegetation. Another drug with a similar effect, which is also used during the growing season, Warrant.

    Aktara is introduced under the root system, with drip irrigation. Iskra M is a broad-spectrum drug that helps to quickly get rid of many pests that can settle in a greenhouse. Processing should also be carried out during the growing season.

    Folk recipes against the moth

    Most gardeners prefer to deal with whitefly on tomatoes using proven grandfather's recipes. Such methods are completely safe and contribute to the health of plants. Garlic tincture helps to effectively get rid of whiteflies on tomatoes. For 1 liter water put a couple of peeled heads of garlic and insist about 10 days. Then spraying is carried out.

    Very often, a solution of potassium permanganate is used for watering and treating plants. A very long time ago, people began to use methods of treating plants from pests with soapy water. With a small number of insects, this is a sure way to defeat the whitefly. Decoctions of dandelion roots or aloe leaves are often used. Processing should be carried out at least once a month.

    The frequency of spraying and watering will be determined by the number of insects, as well as the condition of the plants themselves. It is not recommended to use means to get rid of other insects to combat whiteflies. The fight against this type of parasite is complicated by their immunity to most chemicals.

    Whitefly in the garden damages vegetable and berry crops

    Whitefly in the garden: a description of the pest and signs of damage

    In the process of development, the whitefly caterpillar absorbs plant juices. As a result, growth slows down, vital processes decrease. It is also dangerous because it is often a carrier of infectious diseases.

    With the defeat of insects of plant crops, yellowing and twisting of the leaves, wilting of the buds can be observed. To understand how to deal with the whitefly in the garden, you need to know about the features of its life.

    Adults harm plants by releasing fecal pollen. This substance corrodes and deforms the surface of the culture. At the same time, the insect population is constantly growing - as females lay on inside egg leaves.

    A serious problem is that preparations for the destruction of adult pests are useless in the fight against larvae. Therefore, if you notice this insect in the garden, comprehensive control measures are needed.

    There are many ways to deal with insects, the most effective is the use of chemicals: Aktara, Malathion, Neudosan. But whitefly eggs do not let chemicals in, so spraying courses are carried out systematically as larvae appear.

    Folk remedies are less traumatic for plants. With the help of various traps, infusions, solutions and fumigators, adults can be quite effectively neutralized and the crop saved.

    Whitefly control on cabbage and cucumbers

    Recognizing the appearance of a pest is quite simple. If you notice flying cabbages or cucumbers near small insects light ash and white color time to sound the alarm. And if you shake a few leaves, dozens of butterflies will fly into the air.

    Pests feed on the juice of leaves and stems. As a result of their vital activity, a specific sticky coating is formed on the surface of plants - a suitable environment for the reproduction of bacteria and infections.

    Chemicals

    If a whitefly is found on cabbage, control measures include the use of all available means. For processing, use Ciermetrin, Actellik and other hormonal insecticides designed to kill sucking pests. Chemistry should not be used for processing 3-4 weeks before harvest, as well as during the flowering period.

    Biological and folk methods

    If a whitefly is found in the garden: how to get rid of it quickly, but not harm the plants at the same time, is a paramount question for the gardener.

    One of the most the best means the fight is Verticillin based on the fungus Verticillium lecanii. This is a biological and completely safe drug that does not harm plants, the environment, and human health.

    In addition, the affected plants are treated with a garlic solution prepared in the proportion of 100 grams of minced garlic per glass of water. The mixture is infused for 6 days, and for processing, 5 grams of the solution is mixed with 1 liter of water.

    Lime mortar is well suited for the destruction of insects in the greenhouse. To prepare it, they take half a kilogram of bleach, dilute it in 12 liters of purified water, insist 5 hours and process the cultures.

    In parallel, the leaves should be inspected for egg laying. If eggs are found, they should be thoroughly washed off with a sponge dampened with soapy water.

    Whitefly on tomatoes: control measures, folk remedies

    Tomatoes are more likely than other crops to be affected by the whitefly. Pest control is complicated by the fact that insects can simultaneously be present on the plant in three phases of development at once - eggs, larvae, butterflies.

    • sticky whitish coating on the leaves;
    • twisting and yellowing of leaves;
    • the formation of necrotic spots;
    • detection of larvae during visual inspection.

    Disinfection of the greenhouse and soil

    An insect may appear as in open field, as well as in the greenhouse. Infection of greenhouses treated with disinfectants is possible through purchased soil, seedlings. To treat greenhouses after infection with a whitefly, Ecocide C is used, fumigation with sulfur checkers, the inner surface is washed with a solution of lime or 1% iron sulphate.

    For the prevention of imported soil for greenhouses, or to level the surface of the site, they are treated with fungicides Alirin B, Baikal-EM1.

    Beneficial insects

    The fight against whitefly on tomatoes can be carried out by completely biological methods, involving breeding in greenhouse conditions. beneficial insects that destroy the pest.

    This group includes ladybugs, lacewings, macrolofuses. This method is completely safe for plants and the environment, but is effective only with the primary signs of damage.

    The approximate cost of five hundred Encarsia individuals is 300 rubles. You can buy it in specialized stores for gardening, it is recommended to place it in a greenhouse during the day. The fight against whitefly on cucumbers with the help of beneficial insects is not effective due to the hairs on the leaves in which the pest larvae hide.

    Folk ways

    • spraying tomatoes with yarrow infusion (100 grams per 1 liter hot water);
    • application of tincture of dandelion roots (80 grams of plant roots per 1 liter of boiling water)
    • using garlic tincture diluted with water.

    If the situation is running and the whitefly has managed to noticeably harm the plants, it makes sense to use special chemicals. You can use the same as for processing cucumbers and cabbage. In greenhouses, treatment with Vertimek, Fitoverm, Pegasus is recommended.

    Berry protection and whitefly control on strawberries and grapes

    Often the whitefly starts on strawberries or strawberries. If measures are not taken in time, the insect can not only negatively affect the taste of berries, but also completely deprive the gardener of the crop. The waste products of the pest are a favorable environment for the formation of soot fungus, which levels the processes of photosynthesis.

    The whitefly is less common on grapes; in this case, the control measures are the same as for strawberries. For fruit and berry crops, the most effective means are:

    • sprays with the active substance fipronil;
    • chemicals Actellik, Aktara, Pegasus;
    • biological methods based on the effects of insects;
    • folk remedies with the use of solutions and infusions.

    When choosing a method of struggle, you need to consider general state plants and the concentration of whiteflies in affected areas. It is necessary to take action at the first sign of an insect attack, since these pests tend to multiply rapidly and spread to other crops.

    Preventive measures to protect the garden from whiteflies

    The whitefly can live and breed indoors and outdoors. After winter, the insect can enter the greenhouse along with the seedlings.

    The insect may move to planting material With indoor plants. It is recommended to regularly inspect all home flowers, and disinfect the tools and containers for planting periodically. To minimize the influence of an insect, you need to plant plants correctly, respect the neighborhood, and avoid accuracy.

    Outcome

    The whitefly can cause serious damage to garden and garden plants if proper measures are not taken when it occurs. When using traditional methods of protection in combination with prevention and careful care of plants, you can count on a minimal risk of pest damage.

    If suddenly you find that a whitefly on tomatoes has appeared in your garden, then in no case do not let things take their course. The whitefly is an insect that harms not only tomatoes. Other vegetables, as well as greens and flowers, can also get under the hot hand.

    Whiteflies are small, no more than 3 mm in length, flies with wings covered with a former coating. They inhabit the plant large quantities. Their greatest accumulation, as a rule, is on the underside of the leaf. The main harm that the whitefly causes on tomatoes is the feces that it leaves on the leaf, as a rule, on its upper part. Initially, they look like a shiny plaque. Later, in places covered with such a coating, soot fungi form, which are first white and then black.

    The fight against whitefly on tomatoes begins with the prevention of its appearance. For this, plants that are threatened with whitefly damage are seated in well-ventilated places with no high temperature, possibly 14-15 degrees. Because main reason the appearance of an insect - too close arrangement of plants in poorly ventilated places with high temperature and humidity.

    If whiteflies have already infested stands, control measures should be aggressive. To begin with, if the plants are inhabited by adult midges, it is necessary to place glue traps nearby. Available for sale fit perfectly. adhesive tapes intended for flies. You can make these traps yourself. To do this, paint pieces of cardboard or any other material in bright color, for example, yellow or white (this way you will attract insects to the bait), and then grease the surface castor oil or vaseline. Insects, sitting on such a surface, will stick.

    The next step, thanks to which the whitefly on tomatoes will disappear, is spraying the plants using various chemicals. According to the advice of experienced gardeners, an effective folk remedy for the fight against whiteflies is from a pharmacy, for the treatment of scabies. Of course, you need to buy not an ointment, but an emulsion, which, after dilution with water in a ratio of 30-50 grams of the product per liter of water, will become a composition for spraying damaged plants. Do not forget to wash off the insects and plaque covering the leaves with water, only then proceed with the processing. Spray the plants every few days until the whitefly on the tomatoes is completely gone.

    Another folk remedy is an infusion of garlic. To prepare it, pour about 150 grams of garlic with a liter of water, close the container with the composition tightly with a lid and insist for 5 days. After the specified time, the tool is ready. Dilute about 6 grams of infusion with a liter of water and spray the plants at the same frequency and in the same way as in the first case.

    If folk remedies, which are rather mild, do not help, do not delay with a complete cure and proceed with the treatment with pesticides. When choosing a drug, carefully study the instructions for use - not all products are safe for all types of plants. Consider the location of your plantings: some products are recommended for indoor use, and some outdoors. The method of use for various drugs is different: some are used once, while others require a course of procedures.

    Greenhouse tomatoes most often suffer from pests of various insects. A frequent guest on tomato beds is the whitefly, which affects the lion's share of plantings with its detrimental effect.

    Description of the insect

    The whitefly is a microscopic flying insect (body length is 2-3 millimeters), originating from the family of homoptera. Its tiny body is painted yellowish, and a pair of wings, which are twice the size of the insect itself, have a whitish-mealy hue. From a distance, clusters of whiteflies resemble aphids. The sticky sugary secretions that the pest leaves behind form a sooty fungus, which causes great harm to the tomato bush.

    Fact!

    The whitefly loves to settle not only on tomato bushes, but also on cucumbers, eggplants and others. vegetable crops.

    Females lay their eggs directly on plants, or rather on the lower part of the leaves. In one clutch, you can count from 130 to 200 eggs. During the season, up to 15 generations of new whiteflies appear. The pale green, flat, needle-like larvae that emerge are very voracious. They feed on the juices of the leaf plate, as a result of which it quickly dries out and falls off. After the spirit of molting, the larvae turn into so-called nymphs, from which, after a couple of weeks, adults fly out.

    The humid and warm climate of the greenhouse is an ideal habitat for the whitefly. When the temperature drops to +10 degrees, adults die, while eggs can even withstand frost.

    Note!

    The whitefly is a peddler viral infections.

    Signs of a pest

    The whitefly appears on the bushes already 10-14 after planting the seedlings. It is quite easy to notice a breeding whitefly colony in a greenhouse, as the pest attacks the tomatoes with the whole flock. From this above the bushes you can see a white swarm of midges,
    which upon closer inspection turns out to be a whitefly.

    The underside of the leaves is completely covered with small yellowish clusters - egg clutches. And the "dining" places of the whitefly are covered with a viscous whitish dotted coating - a waste product of the insect. Pest, coupled with the development of an introduced infection, retards the development of plants. Stem atrophy occurs. Foliage turns yellow at the edges, curls, dries out. Rotting ring stains appear on the fruits.

    Fighting methods

    Getting rid of the ubiquitous whitefly is difficult, as its population grows rapidly throughout the summer. Therefore, it is necessary to systematically fight against small dirty tricks throughout the entire growing season of tomato bushes, competently using chemical, biological, mechanical and, of course, folk methods.

    Biological methods

    The safest and most effective methods that also do not require large investments. Why is the whitefly not very common in open ground? The answer is simple: because in unprotected areas, she herself is in danger. She loves to feast on God
    cows, lacewings and other predatory insects. It is difficult for them to get into the greenhouse, and therefore the whitefly feels at ease there.

    If you want to get rid of the annoying midge as soon as possible, then it is enough to put its biological enemies in the greenhouse - a dozen ladybugs (or other insects, such as macrolofus bugs, ecrasia, riders), which will quickly catch all flying individuals.

    For a more sophisticated hunt, an encarsia predator is suitable, which will “solve the issue” with the young whitefly offspring. It lays eggs directly into its larvae and then feeds on them. It remains only to get rid of adults.

    Advice!

    Do not put cow dung under tomatoes - it makes the soil fertile for various pests to settle in it.

    A good help in pest control is the fumigation of the greenhouse. It is carried out during the preparation of the greenhouse for sowing. Various mixtures are prepared for processing. The means of fumigation include:

    • tobacco checker;
    • a sulfur candle;
    • smoke bomb.

    Such manipulation allows you to get rid of pests of all ages.

    Folk methods

    Application folk remedies often effective in cases where the whitefly has just appeared and has not had time to lay offspring. For this purpose, tomatoes are sprayed with various decoctions and herbal infusions that the insect does not tolerate. In addition, they are absolutely harmless to plants and humans, they can be used several times per season.
    One of the "tasteless" means is an infusion of garlic or tobacco. The insect repels and the smell of yarrow on the leaves of a tomato bush.

    A mixture of dandelion (roots) or aloe that has fallen on tomatoes also disgusts the whitefly, and it flies away forever in search of new food. Well, everyone's favorite soap solution will cover the leaves with a barely noticeable film that will reliably protect the tops from various pests.

    Advice!

    Before processing plants, it is necessary to remove plaque and adult moths from the greenery.

    Mechanical methods

    They are considered additional, but, as practice has proven, they work very effectively. If various flying animals have just started up in the greenhouse, then you can collect them “manually”, or rather on sticky traps (fly traps or cardboard baits made with your own hands with the addition of a sticky layer - honey). Bright plates hung in different parts of the greenhouse will attract attention and "catch" pests. It remains only to remove the affected fragments from the tomato and burn them outside the greenhouse. If clutches of eggs are found, they can be removed with a sponge moistened with soapy water.

    Fact!

    Studies have shown that insects are attracted to blue and yellow A. Therefore, all baits perform exactly in this color scheme.

    Chemicals

    And finally, if all other methods have not shown proper results, heavy artillery is used. Chemicals are very effective in controlling greenhouse pests, but meanwhile they are toxic, and therefore they must be used carefully and only before the tomato begins to ripen. Otherwise, poison will get on the fruits.

    Note!

    Treatment with chemicals is stopped 21 days before harvest.

    Basically, all insecticides help to cope with several types of insects at once. So,
    for example, the preparations "Aktellik", "Malathion", "Aktara", "Cypermethrin", "Iskra-M", "Talstar" also save from bedbugs and aphids. Well-known targeted drugs also include: Verticillin, Confidor, Rovikur, Mospilan, Pegasus, Fufanon. In case of severe damage by bloodsuckers, the treatment is repeated 2-3 times, but only according to the instructions. Thoughtless use of chemicals can lead to damage to the crop.

    Of the known means, aerosols "Kra-Deo", "Super" are considered the best.

    In addition to chemical preparations, fumigators such as Biotlin and Warrant can handle the whitefly.

    Prevention

    In the fight against the whitefly, all means are good, but it is better not to allow the annoying pest to tomato plantings at all. Taking preventive measures will significantly reduce the risk
    the appearance of an insect and will help preserve the crop.

    Prevention includes:

    • seed treatment before sowing with a manganese solution;
    • destruction of the weed after harvest;
    • deep digging of the soil in the offseason;
    • incorporation into the soil of only rotted organic matter;
    • not leaving manure heaps for the winter - this is a great place for the wintering of the whitefly;
    • maintaining the distance between seedlings for better air circulation;
    • greenhouse microclimate control (regular airing, competent watering);
    • the acquisition of varieties resistant to diseases and pests;
    • adding a handful of chicken manure to the wells when planting seedlings - this will increase the immunity of the tomato;
    • regular tillage - weeding, loosening, airing.

    Conclusion

    Each gardener independently chooses a way to get rid of the pest, depending on the growing conditions of tomatoes and the number of insects. Methods can be combined with each other or used locally. The main thing is to do everything on time and following the instructions - only then you can defeat the enemy.
