Ways to fight

You can start fighting right in the greenhouse. There are various means of struggle. One of the means is a special trap that is smeared with glue. Today it can be found in special stores or make it yourself. We take a yellow cardboard and cover it with Vaseline. Whiteflies will fly to this color and then stick. With this method, they stick around the entire cardboard - then just wipe it and apply Vaseline again. Also, the insect can be killed with an emulsion from scabies. Dilute 100 g in 1.5 liters of water and spray everything.

Another folk remedy that will help get rid of the pest is a solution of yarrow. It is necessary to grind 90 g of yarrow in 1 liter. water and leave in the shade for one day. Then strain it, and process the tomatoes with this solution.

Also, laundry soap concentrate gets rid of them well. Rub the soap on a grater and dilute it with warm water in proportions of 1:6.

An excellent remedy for whiteflies is garlic tincture. Chop 20 g of garlic, pour 4 liters. water. Infuse it for 24 hours, and then strain. Spray tomatoes with this infusion in the evening.

You can also try to save the tomatoes with a jet of water. You can try to wash off young moths with water from a hose. And after that, you should loosen the soil under the bushes.

However, before spraying, you need to clean the plant from plaque and adults. You need to spray a tomato no more than 2 times a week.

If you find the pest too late, then you will need to apply radical control methods. You will have to use chemicals. In addition, you will need to treat them not only with tomato bushes, but also with nearby plants, otherwise they may become infected.

Now there are many different chemicals to fight whiteflies. Aktelik, Confior, Pegasus, etc. In the instructions you will learn exactly how, and in what proportions to use them.

Aktara is a very popular whitefly remedy. It has a long period of action (about a month or two of protection). In order to kill the whitefly, the tomato is watered with Aktara's solution under the root. Nothing more needs to be done. They feed on plant sap. The reagent, in turn, gets into it, and all pests die. In order to kill the whitefly, you should immediately make Aktara's solution, 4-5 times more concentrated than usual. In order to make the mixture “for slaughter”, we dissolve the contents of the package in 2-2.5 liters of water and pour over the tomatoes!

Confidor is a very strong insecticide. Within 2 hours after watering, the pests will begin to die. Two treatments are enough to "kill" the whitefly.

Akarin kills the whitefly spider mites and even some subspecies of root-knot nematodes. This insecticide is used for spraying. You need to moisten the leaves and get on the pest.

Spark. Produced in the most various subspecies. Instantly gets into plant tissues and stays there for a month.

Phytoferm - kills almost all pests. It will be enough to spend just a few sprays in order to kill the whitefly.

Akkelik is another “killer mixture”. However, it is worth remembering that it has a 2nd class of toxicity and a very unpleasant odor.

Whiteflies also hate the cold, so to get rid of them, they can be moved to a colder room. They can even be caught with sticky fly tapes!

Prevention

Firstly, you do not need to do a dense sowing, as this will disrupt the air circulation, and the infection will take place at lightning speed, it will be useless to fight the pest here. It is necessary to ensure the ventilation of the plantings, and also do not spray the plants in wet weather. If possible, then lower the temperature to 10 degrees for several days, since when the temperature drops, all adults and almost all larvae die.

The fight against the whitefly can go into season. Chemicals have a very bad effect on both plants and people and even pets. Therefore, it is better to prevent the danger than to deal with it later.

Immediately after disembarkation, it is necessary to carry out folk prophylaxis with proven methods. If you decide to plant tomatoes in a greenhouse, then you need good ventilation, and the air temperature should not rise above 15 degrees Celsius.

Secondly, it is best to paint the greenhouse before planting. The earth must be removed from last year's grass, and then everything must be dug up. Do not leave compost for the winter, because this is a chic location for the winter "lodging" of the whitefly! In cold weather, you should open the greenhouse so that the pests freeze! If you purchase seedlings, then carefully check the plants!

You can still carry out autumn prevention, as folk experts advise us!

The first spraying is done right after the harvest, the next is done after the diseased plants have been removed. The tomato is treated with a 0.5% emulsion of karbofos. If you have a well-sealed greenhouse, then instead of a second spray, try fumigating with a sulfur lump. Set fire to lump sulfur and keep the greenhouse closed for a couple of days. In addition, it is necessary to do disinfection with sulfuric gas. 110 g of sulfur should be set on fire per 1 square meter of the greenhouse. Weeds should also be removed. In addition, observe the distance between vegetables. No need to plant them near the greenhouse. Vegetable greenhouses must be located at a distance of more than 10 meters from flower greenhouses.
