What to choose for the destruction of white midges on tomatoes?

Tomato beds are quite often attacked by a pest such as whitefly. It settles on the lower part of the leaves and sucks nutritious juices from plants. At the same time, adult individuals that look like small moths and larvae parasitize, and as a result, the quality of the crop can be very affected. And if you have found white midges on tomatoes, then this is a pretty serious problem. Procrastination on your part can turn into the fact that the leaves on the bushes begin to gradually turn yellow, dry out, and the fruits ripen unevenly.

Signs of infection

On tomatoes, white midges start up exclusively in the greenhouse, and infected plants are quite easy to recognize. The leaves on them are yellow and twisted, the development of the fruits proceeds unevenly, and their inner tissues turn white.

Recommendation! And to make sure that you are really dealing with a whitefly, just touch the affected bush - a small midge immediately rises into the air.

In the process of their life, insects secrete a transparent secret that can be found on the upper surface of the leaves. After a while, this coating darkens and turns into black. These are sooty mushrooms called mob. Gradually, black plaque spreads to the stem, fruits, which spoils their appearance, and adversely affects the quality of the crop.
At the same time, the mob is far from the only disease that can be "awarded" to midge tomatoes. In addition to this pest, it also carries some viral diseases, including curly leaves, chlorosis and jaundice. As a result, the leaves are deformed, necrosis of the stem tissue and fruits of the plant develops, the growth of shoots is noticeably slowed down.

It is worth noting that it is the whitefly larvae that cause the most harm. And if only adult individuals were found on tomato bushes, this means that no serious damage has yet been done to the tomato plantings.

Important! However, even in such a situation, it is necessary to choose a drug that will prevent the active reproduction of pests and protect the crop!

Preparations for the fight against white midges on tomatoes

In the fight against small white midges on tomatoes, it is important to take into account the fact that not every drug is able to destroy the pest at all stages of development. In addition, the wax coating that forms on the leaves to some extent protects the parasites below it from the destructive effects of poisons. For these reasons, in most cases it is necessary to apply several different tools and methods at once.

How to get rid of white midges on tomatoes?

Greenhouse fumigation

This event is held at least twice a year. For this, you can use sulfur candles. Only before starting to fumigate the greenhouse, all plants from it must be removed.

If the greenhouse is located close to the house, then in this case it is better to use checkers based on standard insecticides, while vegetable crops can not be tolerated.As a result of fumigation, not only larvae will die, but also whitefly pupae.

Biological preparations

This is the most sparing option, since such funds are not aggressive. They are based on microorganisms that can parasitize on a whitefly, which as a result leads to the death of the entire colony of the pest.

Cardboard sheets on which the pupae of this biological “weapon” are located are hung on tomato bushes. After some time, the ripened offspring moves to the infected parts of plants and gradually destroys whitefly larvae and individuals that are in a stationary stage of their development.

Chemicals

Such drugs can be systemic, which penetrate the body of the plant and make its juices poisonous to whiteflies, and contact, working with direct contact with the body of the parasite. This is the fastest way to get rid of white midges on tomatoes. Only use any insecticide strictly according to the instructions. The most popular products from this group include:

• "Fufanon";
• Confidor
• Mospilan;
• "Fosbetsid";
• "Actellik";
• "Pegasus".

And sometimes a single processing is quite enough.

Important! If you chose the chemicals to fight white midges on tomatoes, remember that using one drug all the time is highly discouraged. Otherwise, the whitefly will develop resistance, and the tool can no longer be effective!

Do not forget that after applying chemicals to the treated plants, you must create a shadow. Otherwise, burns may appear on the leaves. In addition, the components of these products accumulate in the soil, after which it is quite difficult to clean it. For this reason, they should not be used too often.

Folk recipes

With the appearance of midges on tomatoes, toxic substances are far from always necessary. In some cases, folk remedies and methods are quite effective. The simplest of them involves the use of low temperatures. It is enough to just take out the infected gnats on the street and leave until morning.

Important! This method is suitable only for cold-resistant varieties, and such an event can be held in early spring, when the air temperature is still quite low. And when the thermometer drops below + 15 ° C, the whitefly will die!

• Yarrow infusion. Pour a kilogram of plant leaves with a bucket of water and leave it warm for two days. After this time, we filter the product and process the infected plantings. Spraying should be carried out two to three times with a weekly interval.
  
• Soap solution. Grind the bar of laundry soap and dilute in water at a ratio of 1: 6. The solution should be concentrated. Beat it in foam and use a soft sponge to apply on the leaves or spray the bushes from the spray gun. Soap solution is not washed off.
  

  On a note! Soap solution perfectly copes even with numerous colonies of white midge on tomatoes!

• Garlic infusion. To prepare this product, you need to chop 10 cloves of garlic and pour the resulting mass with five liters of water. The infusion is left warm overnight, after which it is filtered and applied on infected plants.

Prevention

To destroy white midges on tomatoes, you will need to spend a rather long period of time, and when using insecticides you can harm yourself and your plantings. It is much simpler and better to carry out proper prevention.

• Since the whitefly dies at + 15 ° C, greenhouses should be ventilated more often in early spring - this event will significantly reduce the risk of the appearance of the parasite.
• In addition, you need to regularly weed plantings, removing weed grass and tomato leaves.
• Dig the beds, from time to time, process the metal elements of the greenhouses with soapy water and do not store compost in the garden.

These simple measures will be enough to make tomato plantations unattractive for white midges. Have a good harvest!
