An effective remedy for whiteflies on tomatoes. What to do if a whitefly appears on tomatoes in a greenhouse. How to get rid of the whitefly: passive remedies

The whitefly on tomatoes is quite common, and the damage that it can cause to a future crop is simply enormous. A small butterfly up to 3 mm in length. Its larva feeds on plant sap, as a result of which their leaves become discolored, which sooner or later leads to the death of tomatoes. The method of reproduction is through egg laying. One adult female lays up to 250 eggs during her life cycle. If you find traces of whiteflies in the area, act immediately. This will help you not only chemicals, but also numerous folk recipes, the effectiveness of which has long been known.

Problem symptoms

How to choose the time to process whitefly tomatoes? Sometimes this is not so easy to do, especially if you visit the site exclusively on weekends. You can suspect a problem by several characteristic signs:

• hovering over the beds with tomatoes, a white midge, somewhat reminiscent of a moth;
• a white cloud over a bush, if you shake it a little;
• translucent, barely noticeable, scales covering the lower plane of the leaf plate;
• sticky and shiny plaque, which is popularly called honeydew (it, in fact, is a product of their vital activity);
• a lot of dark or black spots resulting from infection of the plant with a soot fungus - a frequent companion of the whitefly;
• a significant lag in development;
• yellowing and curling of the leaves.

If you observe several signs from this list, then this means that the whitefly on tomatoes can significantly reduce the future crop. But any measures will be highly productive if you start the fight at the stage when the butterflies appeared, and their larvae are not yet found on tomatoes.

How to get rid of the whitefly: passive remedies

In general, their effectiveness is somewhat lower than that of traditional chemicals, but if you want to feast on organic tomatoes, their use definitely makes sense.

At this stage, just traps are ineffective - you need to connect chemicals

Glue traps

A remedy for whiteflies on tomatoes, which they are most suitable for greenhouses. although, with a strong desire, such devices can also be used outdoors. The products of the Pheromon, Bona Forte and Argus companies have proven themselves well. They are absolutely safe for health, however, with a large planting area, their use is not justified from a financial point of view. On the other hand, sticky traps can greatly damage the development of the population of beneficial insects that pollinate crops.

Attention! You can make a trap with your own hands. This will require yellow cardboard and long-drying glue. Cardboards smeared with this composition are hung around the perimeter of the beds. Alternatively, grease or honey can be taken as an adhesive. As you fill with stuck butterflies, the cartons need to be changed.

Fumigators

In fact, they are no different from those devices that many are accustomed to using to fight mosquitoes at home. In terms of efficiency, they differ little from glue traps and in most cases allow not to treat whitefly tomatoes with chemistry. Their disadvantages include serious financial costs and problems that may arise with a sufficiently large area of ​​​​the site.

Chemistry to help

To treat whitefly tomatoes with chemicals, you must choose dry, calm weather. It is better to spray in the evening to avoid burns to the plant. No need to chase for instant results and use hypertoxic drugs. They accumulate in the soil and from there will fall into the fruits.

• "". For 10 square meters you will need a solution of 10 ml of the active substance and 10 liters of water.
• "" from the whitefly has a similar application pattern. Depending on the number of pests and the type of soil, from 0.5 to 2.5 liters of water and 5 ml of the drug will be needed to treat 100 square meters of land. It is necessary to apply the solution with an interval of 15-20 days 3 times.
• "". One sachet (4 g) is enough to process 6-7 acres (0.6 g of the drug and 4 liters of water per 1 weave). The duration of the drug - no more than 4 weeks.

Important! The whitefly, like other garden pests, after 2-3 treatments with the same insecticide, develops immunity to it. Therefore, if it cannot be removed from the beds, this is the reason. The correct model of the gardener's behavior is the alternation of chemical preparations.

Ways to protect folk remedies

Folk remedies for the fight against whiteflies do not require significant investment. With timely use, they show a fairly high efficiency and safety for health. But if the situation is out of control, and pests have completely occupied your site, they may not be enough to improve the situation.

• Rubbing the leaves with cold water (best with a little soap added). A good method if you need to process a small number of bushes. Thus, the larvae and eggs will be destroyed, which means that the spread of the population can be avoided.
• Reducing the air temperature to 10 degrees is only relevant for indoor areas. A very effective method, but it involves serious material investments in the purchase of special climate equipment. It should also be remembered that some eggs and larvae can still survive the conditions of the "ice age".
• Infusion of garlic. For 2 small cloves you will need 1 liter of water, after which the infusion should be kept for at least a day in a dark and cool place. It is necessary to spray tomatoes from whiteflies 2-3 times (the interval between procedures is 1 week).
• Infusion of yarrow. It is prepared very simply: combine 80-90 g of carefully crushed leaves with 1 liter of water, mix everything well, leave to infuse for 2-3 days and then strain. The scheme of application is the same as that of a soap solution.

How to prevent infection

The fight against whiteflies on tomatoes, no matter how, will be as effective as possible if the activities are carried out in conjunction with proper plant care.

• Do not spray plantings at high humidity. The effectiveness of the procedure is critically reduced.
• Ensure seating is ventilated. In an open field, this recommendation does not make much sense, but in an enclosed field (whitefly on tomatoes in a greenhouse or conservatory), a constant supply of fresh air will significantly reduce the likelihood of infection.
• Use specially formulated biostimulants designed to improve plant health. Good results are shown by such preparations as Domotsvet, Amulet and Epin. Their undoubted advantage compared to traditional means is a much more sparing attitude to health, so if you have a choice, you should prefer them.
• Do not thicken the landings. Some gardeners try to use the area of ​​the site to the maximum, which leaves not enough space between the sprouts. In addition to the fact that yields suffer from this, the lack of free space leads to the activation of pests, and most drugs that can kill the whitefly will show much lower efficiency.
• Use special varieties of tomatoes that are resistant to pests and diseases. You will have to pay a little more for them, but if the whitefly is quite common in your area, it is worth spending a little. The most popular varieties in our country are Akademik Sakharov, Arkino, Vystavochnik and Salting Miracle. It is also worth taking a closer look at the "Orange Giant", "Heart of America", "Estonian" and "Giant Charm".

We dare to assume that you have your own well-established schemes on how to deal with whiteflies on tomatoes. We will be glad if you share them - a lively dialogue always allows you to find new solutions to the problem.

One of the most insidious garden pests is the whitefly. This small insect, whose length does not exceed 2.5 mm, is distinguished by its exceptional ability to reproduce. Voracious insects are able to completely destroy cultivated plants growing in closed ground.

And if the heat-loving whitefly needs a sufficiently high ambient temperature to exist in the open air, then in greenhouses and hotbeds it can exist year-round, causing irreparable harm to greenhouse plants.

Of the one and a half thousand species of insects of the Aleirodidae family, the greenhouse (greenhouse) whitefly poses a particular danger to crops. The homeland of this harmful moth is South America. This explains the special “love” of whiteflies for greenhouses and greenhouses, where a warm and humid climate is maintained.

In one calendar year, the whitefly is capable of producing 15 generations. When the air temperature drops to 10-12 degrees, the pest's ability to reproduce decreases, but the butterfly calmly waits out the cold weather in the upper layer of soil or in the remains of plants.

whitefly growth stages

The complete transformation of the pest from an egg into a sexually mature individual occurs in 25-40 days. The more favorable the conditions for the existence of a butterfly - moist air and room temperature - the faster the whitefly "ripens". The life cycle of the whitefly is four “ages”, in each of which the butterfly harms garden and garden crops.

1. Stray larva - hatches 11-12 days after laying eggs. The value is 0.25-0.3 mm, intensively spreads over the surface of the leaves in search of the most favorable habitat.
2. Nymph larva - after 5-6 days, it is tightly attached to the wrong side of the leaves of the plant. Having pierced the leaf, the nymph feeds itself on the juice of the foliage and remains completely immobile until the next stage of growth is reached. Visually determined with difficulty, it looks like a thin scale of a greenish tint. During its existence, it is covered with a waxy secret, which makes it invulnerable to insecticides.
3. The pupa is the final stage of development of the whitefly, lasting from 7 to 30 days.
4. Formation of adults (adult whitefly), ready to devour the plant.

An adult female whitefly lives for about 30 days, during this period she is able to lay up to 140 eggs. For this reason, often one greenhouse plant can become a haven for a harmful butterfly at all stages of development - from egg colonies to hundreds of adult moths.

In the absence of timely processing, the plant is doomed to an early death - the larvae deprive it of vitality by drinking juice, and adults eat the fleshy part in a matter of days. In addition to a direct threat, the whitefly is a carrier of many viruses. The larvae also produce a sugary substance, which is a beneficial environment for the habitat of fungi. Very often in greenhouses where the whitefly is common, plants are damaged by niello, a type of soot fungus.

How to recognize a whitefly lesion

Whitefly infestation at the initial stage is not easy to detect. This is due to the fact that the insect nests mainly on the wrong side of the leaves, and its larvae are so small that they resemble small scales.

One of the characteristic signs that the plant is affected by the whitefly is the appearance of whitish or yellow spots with blurred borders. Plants acquire an unhealthy, oppressed appearance; on the underside of the leaf, you can see light tubercles - places where second-age larvae accumulate.

When examining the leaves, their deformation, twisting is noted. After a short time, the affected leaves turn yellow and die.

The secretions of the larvae cover the plant with a sticky coating, which is easily detected when touched. This plaque clogs the pores of the leaves, prevents natural photosynthesis and the normal development of the plant. If black velvety spots are found on the leaves, then we are already talking about a concomitant disease - a sooty fungus that whiteflies carry.

If any of the listed signs of an unhealthy plant appear, urgent measures should be taken to save the crop.

How to deal with greenhouse whitefly

Features of the development of the whitefly make the fight against it quite difficult. In order to preserve greenhouse crops, a set of measures should be carried out, including mandatory preventive work.

Greenhouse (greenhouse) processing

The indispensable treatment of greenhouses immediately after harvest helps to reduce the risk of the spread of agricultural pests.

Such prevention includes:

• complete removal of plant residues and debris, followed by incineration;
• applying bleach solution to the frame structure;

Keep in mind! It is extremely impractical to install a compost container in the greenhouse - when plant residues rot, a beneficial environment is formed for garden pests.

Mechanical removal of the whitefly

The simplest and most environmentally friendly method of dealing with whiteflies is the mechanical removal of moths, egg colonies and pest larvae from leaves. This can be done both manually and by washing the plants with a watering hose. After the adults are knocked down, each sheet should be wiped from the front and back sides with a solution of laundry or green soap.

With a large population of the greenhouse by the whitefly, the treatment of plantings with a household vacuum cleaner is effective - this way you can remove a significant part of flying insects.

The disadvantage of this method of destruction of the whitefly is the complexity and the lack of a guaranteed result. Part of the pests after mechanical treatment will remain and continue to destroy plants.

Traps

A variation of the mechanical removal of insects is the use of special traps. They are plates painted in bright colors (yellow, orange or piercing blue) and covered with an adhesive layer.

For self-made traps, you can take a solid base (hardboard, plywood, thick cardboard) and cover it with blue or yellow paint. These colors are the most attractive to harmful insects, so the effectiveness of glue traps to get rid of whitefly adults is quite high.

The painted base must be covered with an adhesive composition, which is prepared as follows:

• mix castor oil, rosin and petroleum jelly thoroughly in a metal container;
• heat the rosin in a water bath to a liquid state, add castor oil, petroleum jelly and honey taken in equal parts;
• mix until smooth and refrigerate.

After applying the adhesive composition to the base surface, the trap is ready for use.

Important! For the manufacture of an "eternal" trap, it is preferable to take plywood or plexiglass as the basis. Such a device can be used many times - just remove stuck butterflies and wash the trap with warm water and soap.

To increase the effectiveness of traps, they must be placed at the rate of 1 unit per 10 square meters. m area of ​​the greenhouse (greenhouse).

Biological method of getting rid of whiteflies

As a safe alternative to the use of insecticides, the use of natural whitefly antagonists is common. This is the familiar ladybug or the well-known lacewing polyphage. Beneficial insects help fight whitefly larvae.

Encarsia - Encarsia formosa

For tomatoes, peppers and eggplant grown in a greenhouse, the predatory macrolofus bug is ideal. The average duration of the existence of the female of this bug is 30-40 days, during which time she destroys more than 2.5 thousand larvae of the harmful whitefly.

Macrolophus - Macrolophus nubilus

Keep in mind! To ensure that the greenhouse is free from whitefly invasion, 4-5 individuals of macrolofus per 1 square meter should be released. m of protected ground. As a preventive measure, it is enough to run 1 bug per square meter.

Biological assistants in the fight against whiteflies can be plants and herbal infusions. Tansy planted in a greenhouse acts as a protective agent.

The following herbs can be used to treat vegetable crops:

• yarrow - grind 80-100 g of leaves, pour water (1 l), leave for 48 hours;
• dandelion - cut into 40 g of roots and leaves and pour water (1 l), infusion time - 2-3 days;
• garlic (1 head) is crushed and poured into 0.5 liters of water, infused for 6-7 days, then diluted at a concentration of 1 tsp. (5 g) infusion per 1 liter of water.

Prepared herbal infusions are used for spraying greenhouse crops at intervals of two weeks.

Insecticidal (chemical) method of killing whiteflies

The use of chemical poisons is an undesirable option for the destruction of harmful insects. It makes sense to resort to it in cases where a significant whitefly infestation is found and biological or mechanical methods of getting rid of it do not help.

For chemical treatment of plants, it is necessary to take those insecticides that are recommended for home use. As a precautionary measure, vegetable crops should be covered with insulating material (e.g. polyethylene) before treatment to prevent the poison from reaching the plants.

Attention! Vegetables eaten without intensive heat treatment (cucumbers, herbs, tomatoes, peppers) cannot be treated with insecticides, since it is impossible to remove poison residues by simply washing.

Table. Effective preparations for the fight against whiteflies in the greenhouse.

Prices for "Intavir"

In a number of insecticides, there are hormonal preparations that act on whitefly larvae and do not have a visible harmful effect on adults. However, when it enters the body of an insect, the hormonal pesticide causes a kind of sterilization of the female whitefly, depriving her of the ability to reproduce. The Admiral drug has proven to be excellent, which requires no more than two treatments to achieve a guaranteed result.

Admiral is a synthetic analogue of a juvenile hormone that disrupts the growth and development of harmful insects.

The fight against the whitefly in the greenhouse requires a lot of effort from the gardener or gardener. In order not to lose the crop, you should be attentive to the plants, inspect them for the appearance of the first signs of pests. To prevent infection, it is advisable to fumigate the greenhouse with sulfuric smoke bombs - after such treatment, the whitefly problem will not arise.

When clouds of midges rise from plants with random shaking, the vegetable grower begins to worry about how to get rid of the whitefly in the greenhouse on tomatoes and other crops. Small insects resemble aphids and cause the same damage by drinking the juice from the fleshy leaves. But tomatoes suffer not only from this.

This insect is a species of homoptera. The size of an adult individual does not exceed 3 mm, and when viewed through a magnifying glass, opaque white wings and a light, almost uncolored body become visible. The flying whitefly looks like an aphid or a small moth.

When several mature insects enter greenhouses and greenhouses, it is quite difficult to notice them, so the gardener pays attention to the consequences of the activity of the larvae:

1. Tomato seedlings develop twisted or deformed leaves that are smaller than normal. On the reverse side, you can see small caterpillars (about 1-2 mm) or traces of their stay: the remains of cocoons and secretions in the form of transparent, glue-like scales.
2. Affected plants lag behind in growth, have a stunted appearance.
3. On adult bushes, the ovaries cease to fill and ripen normally, acquire a pale shade or become covered with a dark bloom.
4. When breeding, whiteflies can already be seen. They swirl between tomatoes and take off from the plant when shaken.
5. Over time, dark spots form on leaves where larvae and their secretions have been seen. This is what a sooty fungus looks like, which reproduces well and grows on a nutrient medium from insect secretions.

If you see signs of a whitefly, get rid of the pest immediately. If this is not done, the larvae will pupate and turn into new flying insects, each female is able to lay more than 200 eggs.

The easiest way is to destroy flying individuals. The larvae on the underside of the leaves are less accessible to the drug. When spraying bushes, you need to take into account their habitats and try to process the leaves from the underside.

When the caterpillars pupate, it will be almost impossible to destroy them. Therefore, the fight against whiteflies on tomatoes should be carried out several times in a row, with an interval of 5-7 days, during which the pupae turn into adult flying insects.

Insect control methods

Control methods against whiteflies on tomatoes can be divided into mechanical, chemical and biological. All of them can be quite effective if you apply them correctly and process the tomatoes several times. These methods are capable of destroying both the adult generation and the larval stage.

There are also folk ways to deal with the whitefly. They are quite harmless to humans, but may be ineffective if the pests have had time to multiply strongly. Folk methods are aimed more at scaring away insects than at their total destruction, therefore, such treatment is best done as a preventive measure if there is the slightest suspicion of the presence of whiteflies in the greenhouse.

Chemical methods of protection

The use of insecticides is a last resort in the fight against whitefly in a greenhouse on tomatoes and other vegetables. All drugs are toxic, and spraying aerosols indoors can be harmful to the owner himself. But with a strong whitefly infection, all means are good.

When choosing how to treat plants, you can stop at special insecticides from sucking pests. They will destroy not only the whitefly, but also aphids, mites, bedbugs and other insects that suck juices, piercing the vegetation cover with their proboscises. From the drugs you can choose: Actellik and Aktara, Cypermethrin and Permethrin, Malathion, Neudosan, etc.

Aerosol Kra-Deo Super is intended for flying insects. It is desirable to use it so that for some time the greenhouse remains closed, and no one enters it for at least a few hours. It is convenient to process the greenhouse at night. Biotlin has a similar effect.

Mechanical methods

The simplest methods are to collect the affected leaves along with the larvae and wash them off with soapy water by hand. This is laborious, but quite feasible when the colonies of larvae are few. Twisted leaves can be cut off and burned. We fight with larvae and a sponge dipped in a solution of laundry soap, gently moving along the underside of each affected leaf.

For flying individuals, you need to make sticky traps. With a small number of insects, a fly tape can be used. But with a massive departure of whiteflies, it is better to make special traps.

American entomologists have discovered that whiteflies are attracted to yellow and blue colors. In connection with this feature of the behavior of adult insects, a method of catching them was developed. To attract pests to traps, they are painted in the indicated colors. The basis of the trap can be a piece of cardboard or plywood.

So, we get rid of the whitefly on tomatoes by the most advanced method. For this it is recommended:

• paint a sheet of cardboard in yellow or blue (A4 format will be enough for 1-2 m³);
• make a hole for hanging, thread the cord;
• apply a layer of petroleum jelly to the surface (you can mix it with honey);
• hang Velcro over the greenhouse area at a height of 1.5-1.7 m.

Flying whiteflies will be attracted to bright surfaces and stick to the viscous mass. Traps are cleaned from time to time, scraping off the mass along with midges. After that, you can apply a new layer of petroleum jelly and hang the cardboard in the greenhouse.

Biological methods

On plants, you can also see a decaying lion, or lacewing larvae. These are small gray insects, with a baggy body, similar to bugs without wings. Often a smoldering lion sticks on itself the shells of the aphids it has eaten. You can transfer the lacewing larva to the greenhouse or look for the laying of its eggs: yellowish balls about 1 mm in size on long, thin “legs” sticking out perpendicular to the leaf. It is easy to catch an adult insect, which is also a predator. This graceful greenish creature with large transparent wings and expressive golden eyes.

In large greenhouse farms, you can try to buy encarsia - a miniature rider that lays eggs in the bodies of whitefly larvae. Insects need to be released from the test tube in their greenhouse. The little helpers will take care of the destruction of pests themselves.

Folk methods

A good way to get rid of whiteflies in a greenhouse is to fumigate the area with smoke. It may help against flying insects and larvae, but the cocoons will remain intact, so the treatment will have to be repeated when a new generation hatches. For smoking, sawdust is placed on a baking sheet, moistened with water and put everything on an electric stove.

To scare off whiteflies that have recently entered the greenhouse, spraying with infusions of herbs is used:

1. Take about 100 g of yarrow herb, grind and pour 1 liter of water. Insist 2 days.
2. Chop dandelions along with the roots, take 100 g of mass and insist in 1 liter of water for 2-3 days.
3. Pass 1 head of garlic through a meat grinder, pour 0.5 liters of water and leave for 2-3 days.
4. Instead of a garlic bulb, you can use its arrows, which are removed from the beds. It will take about 100 g of gruel from arrows and 1 liter of water.

Spray the plantings of tomatoes and other plants in the greenhouse with the resulting infusions to mask their smell with unpleasant odors. If the whitefly does not find its food crops, it will leave the premises.

Growing tomatoes in a greenhouse is a rather complicated process, as it involves a number of mandatory actions and procedures that will help ensure intensive growth and fruiting for plants. The growth of tomatoes in a greenhouse is affected by lighting, air temperature, humidity and watering. Sometimes it happens that fulfilling all these requirements, the owners of the greenhouse cannot protect the plants from the attack of bacteria, fungi or insect pests. The whitefly on tomatoes in a greenhouse is one of the most dangerous insects that infect tomatoes.

In nature, the whitefly is presented in several varieties, but only the greenhouse whitefly "loves" tomatoes.

Whiteflies are a great danger to greenhouse plants. They not only take away all the juices from them, but also lead to the spread of fungi on plants, which lead to blackening of tomato leaves. It happens that moths do not have time to lay their larvae, but only settle on the leaves of plants - this is the most important time to get rid of pests.

Signs of damage to plants by the whitefly:

• Tomato leaves turn yellow and curl.
• The fruits ripen unevenly.
• Inside the fruits acquire streaks of white.
• When you touch the bush, a cloud of white midges rises into the air.

If only midges without larvae were found on the kuta, the bushes should be immediately treated with soapy water or insecticides. Solutions from pyrethrum or pirimiphosmethyl help well. The whitefly is dangerous because it can lead to infection of plants with infections. From this plant can get sick with jaundice, chlorosis or leaf curl.

Dangerous whitefly on tomatoes in a greenhouse: how to get rid of

The fight against the whitefly will differ depending on what stage of development the moths themselves are at. If these are adults, then it is easy to deal with them. They can be destroyed using a variety of drugs.

With larvae, at different stages of development, there will be a tough fight, since a preparation of a certain type acts for each stage of insect development.

A special plaque on the larvae can save insects from the effects of a particular drug. The effectiveness of the method is determined by the intensity of plant damage. To prevent the attack of harmful insects, you can carry out preventive procedures.

Types of insect control:

• Fumigation. Should be done several times a year. If the greenhouse is located remotely from the living quarters, fumigation can be done with the right candles. Checkers with insecticides will get rid of adults and larvae, while not harming plants.
• chemicals. Breed them should be in accordance with the instructions. The use of "Confidor", "Phosbecid", "Pegasus", "Aktellik", "Mospilan", "Fufanon" is considered effective. Sometimes one spraying is enough to completely rid the plant of pests.
• biological methods. Special insects are placed on the bushes so that they destroy the larvae at any stage of their development.

All methods of struggle are effective. Each owner chooses the method of struggle for himself. When working with chemicals, it is very important to take precautions so as not to harm health, plants and fruits.

Chemical control of whitefly in greenhouses on tomatoes

When choosing a chemical agent, you need to be extremely careful. It should not harm the plants themselves. It is very important to ensure that the chemicals do not spread beyond the place where the treatment is carried out.

It is important that the plants are not exposed to the sun after treatment, as they can get burned.

It is dangerous to use aggressive substances, as they not only kill insects, but also soak into the soil, and are removed from there for a very long time. For re-treatment, the drug must be changed, since insects can develop immunity to the same drug.

Types of drugs:

• Insecticide. It gets into the juice of plants, and with it into the larvae that feed on it.
• contact insecticide. Insects die on contact with the drug.
• Soap base. Eliminates a large number of adults.

Whiteflies should be dealt with as soon as they are discovered. Large moths are easy to deal with, they can be scared away by simply spraying plants. But with the larvae, the struggle can drag on. Since a special plaque protects them from death, which not every drug can cope with.

Fight with folk remedies: whitefly on tomatoes in a greenhouse

There are gardeners who vehemently oppose the use of chemicals for pest control. Using chemicals is, of course, effective, but not always necessary. You can fight pests with the help of folk remedies.

The cold does not work well for the whitefly. If the variety of tomatoes allows, they can be temporarily taken out of the greenhouse into fresh air.

If there are a lot of whiteflies, you can catch them with glue traps. To do this, glue should be applied to cardboard, preferably bright yellow. Such traps attract moths.

Spray method:

• Wipe the leaves with yarrow infusion.
• Spray the plants with a weak solution based on laundry soap.
• You can use garlic tincture.
• Plain water can be used to control adult moths.

It is better not to fight insects, but to prevent their appearance. Sometimes the fight against moths takes a very long time and is inconclusive. It is important to prevent moths from breeding.

Whitefly Prevention Tips:

• Frequent ventilation. Moths are thermophilic and do not tolerate temperatures below fifteen degrees.
• Weed plants in a timely manner and ensure that weeds do not grow near the tomatoes.
• For each new planting, the earth must be dug up and treated with special solutions.
• It is impossible that the compost is stored in a greenhouse - this is a cozy place for the whitefly to live.

Preventing insects in a greenhouse is easier than getting rid of them. It is important to notice the appearance of insects in time. To do this, you should carefully monitor the condition of the leaves and fruits of plants. The first signs of the appearance of the whitefly: yellowing and withering leaves, as well as the appearance of white moths.

Pests and diseases: whitefly on tomatoes in a greenhouse (video)

It seems that in the greenhouse the plants are completely safe: the owners monitor the temperature, air and soil humidity. But sometimes these actions are not enough. If yellow spots began to appear on the plants, the leaves of the flock shriveled and withered, the fruits do not ripen so quickly - it means that the whitefly has settled on the leaves of the tomatoes. This is a harmful insect that drinks the juice and water of tomatoes, leading plants and their fruits to death.
