How to deal with the whitefly on tomatoes in the greenhouse?
The little moth lays its eggs on tomato plants, causing its leaves to gradually wither and fall off. What signs of its appearance will allow the summer resident to take appropriate measures? Here are just a few of them: leaf deformation, stickiness, the presence of yellow spots on tomato bushes, twisting. But how to get rid of the whitefly on tomatoes in the greenhouse? According to the reviews of gardeners and experts, there are several methods for its elimination.
Beetles and leaf fleas. 1 kg of dry grass soaked for 2 days in 10 liters of water or potion after soaking is boiled for 1-2 hours. Autumn crocus against caterpillars. A set of dry bulbs for 3 days. Tansy potion, wormwood extract, mild soap solution. Wetting butterflies with fruit juice, molasses and beer baits. Chamomile against sucking, caterpillars and lice. 1 kg dry weight for 10 leagues for 12 hours. Drain and add another 30 liters of water and 120 g of soap. Mistletoe is used to control caterpillars of legumes, vegetables and orchards.
Beautiful plants are used. Cut about 3 kg of fresh leaves and stems and boil for 150 minutes in 3 liters of water. Pour boiling, bring to 8 liters of water and add 5-6 ml of liquid soap. It must be cooked carefully as it is poisonous to humans. It quickly decomposes on plants within 4-5 days. Therefore, it should be sprayed again after 7 days.

Crops, beans and cucumbers: 200 g of finely chopped onions are soaked for 15 hours in 10 liters of water.
Folk remedies in the fight against whiteflies on tomatoes
If the summer resident wants to take preventive measures without the use of chemicals, then you should pay attention to folk remedies whitefly control in the greenhouse. Having studied the reviews of gardeners, they identified the most effective ways:
- glue traps lubricated with petroleum jelly, castor oil, a mixture of rosin and honey;
- spraying seedlings with infusion of garlic or clean water;
- ventilation in the greenhouse will reduce the risk of pest damage, since the whitefly does not like low temperatures, drafts, and quickly multiplies in warmth;
- application of tincture from dandelion rhizomes;
- use of a solution based on laundry soap;
- spraying tomatoes in a greenhouse with a solution of yarrow;
- planting umbrella plants in the greenhouse, such as dill;
- flue placement sulfur checkers near seedlings.
These are perhaps the most basic measures to combat the whitefly, which every gardener wants to get rid of. Before planting tomato seeds in a greenhouse, it would be good to treat the soil with copper sulfate.
The resulting infusion is drained and applied. three times spraying within 5 days during the growing season. It is good to add liquid soap. Garlic for the destruction of aphids, hikes and ticks. Pests of plums, strawberries and other crops. Peel the cloves of 3-4 heads, cut them open and collapse. Leave for 7 hours. Drain and add 6 ml of liquid soap. It is reused within 7 days. Garlic: 500 g of garlic is crushed in a mortar. The resulting suspension is placed in a three-liter container with dark glass and made up of pure water at about the same temperature. 25 degrees.

Turns out it does a lot of damage.whitefly on tomatoes in a greenhouse, how to get rid of from this pest, and what you can do you learned from our article. Timely preventive measures are guaranteed to allow gardeners to protect tomato bushes from a dangerous insect. You should know about them in advance in order to protect the seedlings from the pest.
The court is kept in the dark and warmer for 7 days, then strained. It is used against thrips, lice, ticks. First spray when the buds dissolve, the second after flowering is next. After 15 days. Unhatched colorful buttons and flowers are soaked for 1-2 hours in 10 liters of water. Tattoo against cabbage and beetles. Dried stems and leaves weight 400 g per 10 liters of water. Tattoo 100 g of soil mass is boiled for 1 hour in 1 liter of water. Destroys all kinds of insects. Tobacco against aphids, fleas, trips, leaf rollers, cabbage moths.
Rape and cherry axes. 400 g finely chopped mass of 10 liters of water for 2 days. Drain and add 10 liters of water and 8 ml of soap. They are planted between rows of strawberries. Against aphids, infusions 1 kg 10 liters of water.

Whiskey horse against aphids and mites. Injection 1 kg per 10 liters of water for 1 day.
White midge attacked seedlings of tomato and pepper
Sometimes you can observe how a white midge similar to living mold attacks the seedlings of tomato and pepper - this is a greenhouse, greenhouse whitefly. This pest is very resistant to spraying with various decoctions, and sometimes chemicals. An adult whitefly has a size of 1-1.5 mm.
Her body is almost completely covered by two pairs of white wings. When these insects tightly stick around the plant, it seems as if the leaves are indeed covered with mold. The bulk of the females of this pest is located on the underside of the leaves.
Poisonous chickpea against aphids. Protein against aphids, mites and trips. Stinging nettle extract 500 g of fresh nettles are poured into 4 liters of water, kept for 12 to 24 hours. Without dilution, antispasms are sprayed. Whipped wormwood tea 1 teaspoon of wormwood is boiled in 1 liter of water. Drain the water and leave to cool. Sprayed undiluted against aphids, strawberry jar, pea leaf, axes and more. The path of the ants.
Plant diseases: Mann, rust and bacterial fire on tomatoes. Tansy tea. 30 g of dry tuna stalks are boiled in 10 liters of water. The resulting decomposition is diluted with two parts of water. Mana in Tomatoes: Onions are also used against aphids. Tincture flower stems, bulbs, leaves. Double spray. 1 kg finely chopped green table bears and garlic. Soaked in 3 liters of water for 12 days, 300 g per 10 liters of water; Used when mana is available. Bacterial burning on tomatoes, as well as against powdery mildew of tomatoes.
It is there that females lay 85-130 eggs in 30 days. The greenhouse whitefly often settles on indoor plants, gets from them and onto seedlings of tomato and pepper, which we grow on window sills. The whitefly can get on seedlings from plant residues, from the soil, as well as from the seedlings themselves, if you purchased it in a greenhouse. As a result of its vital activity, the underside of the leaves is covered with white larvae, the leaves become sticky, in some places black spots from sooty mushroom. How to protect seedlings from whiteflies? It is necessary to carry out autumn preventive spraying of plants with special pesticides.
Apple and rust on fruit trees. After cooling, strain and dilute to 1: Fungal infections: 1 medium garlic cloves are crushed and poured into 1 liter of hot water. Poured and allowed to cool, then used. For spraying without dilution. Fungal diseases: garlic, onion, potassium permanganate, potassium thiosulfate. Aronia leaves in June-July. This is a problem with peas, tomatoes, peppers, pumpkins, cucumbers. Bacterial diseases: garlic powder. Grow: Polish horsetail potion, sulfur. Flour manna: whey solution, colloidal sulfur after 8-14 days.
The first spraying is carried out after harvesting, and the second - after the removal of diseased plants. The treatment is carried out with a 0.3% emulsion of karbofos. If you have a well-sealed greenhouse, then instead of re-spraying, you can fumigate with sulfur dioxide at a temperature of +18 - +20 degrees maintained in the greenhouse.
To do this, you need to burn lump sulfur (50g / m3) and keep the greenhouse closed for 1-2 days. It is also worth carrying out a one-time disinfection of the greenhouse with sulfur dioxide - burn 100 g of sulfur per cubic meter of the greenhouse. 2-4 m). Greenhouses with vegetables should be removed from greenhouses with flowers at a distance of at least 10 m. Fitoverm also helps to cope with the whitefly.
Prophylactic potion of Polish horseradish, sulfur. Chlorosis: nettle dung. Curly parsley is used. Seed disinfection: chamomile decoction; Thermal beans, peas, tomatoes. okra. For tomatoes in hot water at 56°C for 30 minutes; Against dry heat treatment with TMB at 56°C for 6 hours, then at 80°C for 24 hours.
Plants That Help: The white mugwort between French grapes protects them from rust. Eggplant and green beans together feed the Colorado potato beetle. Instead of beans, the same effect is achieved with peas. It is not even necessary to plant large numbers. For rows of potatoes up to 10 m, it is enough to leave the end of each row to be planted with one root pea. The Colorado potato beetle doesn't like pumpkins. Pumpkin violins are best for this purpose because they last millions and go through potatoes.

Seedling disease - whitefly
Often seedlings of vegetables and flowers are affected by pests such as whiteflies. These are small-sized insects with a small yellowish body, up to 1 mm long and two pairs of wings, the surface of which is covered with a white coating.
Hold it. Latinana and horseradish repel aphids, caterpillars and mice. Latin enhances the smell of radishes. Latin trees planted in a greenhouse crowd out the annoying greenhouse whitefish. Green lettuce prevents the attack of various types of turnips and cabbages. From the fleas of the earth. Carrots and onions or leeks - mutually protect themselves from carrot flies and onions. Fly and pray. Leek, located between celery, protects against rust on celery and attacks with thrips; Legumes and celery or cucumbers are a very useful combination for good development.
Legumes are sown around the nest of cucumbers. Celery and tomatoes - protect all cabbage from white cabbage butterfly; Spinach or cabbage salad - against earth fleas; Daisy sown between vegetables and fruit trees, throws sculptors. caterpillars. Like a marigold, a tagger works. He successfully participates in the fight against nematodes and lice. Parsley planted under tomatoes enhances the flavor; Gingerbread and mint - improve the quality of tomatoes. Nettle grown for essential oils has increased the content. Essential oils up to 80% of them.
By appearance the whitefly looks like a moth. When plants are affected by such a pest, on the reverse side of the leaf plate, you can see insect eggs, which are stacked in rings of 10-20 pieces each. The fertility of whitefly females is quite high: from 130 to 280 eggs. The larvae are light yellow in color.
The body is covered with short hairs, the eyes are orange-red. The larvae and adults of the whitefly feed on the juice that they extract from the cuttings, leaves and stems of plants. As a result, the parts affected by the pest dry up and then die off. The sooty fungus that appears on the sweet secretions of the whitefly causes a disruption in the process of photosynthesis and a decrease in the immunity of garden and flower crops.
Shipka, elder and mustard are useful plants around the vegetable garden. Celery and Cabbage - Cabbage is not attacked by the White Cabbage Butterfly and Celery. Rust Onions, garlic and leeks provide protection against pathogenic fungi. Peppers in rows of beans - leaf lice run through the beans. Basil to cucumbers - hold manna cucumbers. If onions, garlic or leeks are planted near strawberries or parsley. Then you won't have a problem with gray mold on them. They drive away naked snails, mice and protect strawberries from pathogenic fungi.
Margarita in strawberry against strawberry nematode. Lavender around roses or other cultivated plants crowds out ants. Leaf aphids Horsetail and nettle feed red spiders. Garlic, feverfew and twist sprout aphids. Wheat defeats flies from crops. Cake ate butterfly cabbage. Garlic relieves attacks of tomato cloves. Rosemary and thyme bring butterfly cabbage. The radish will throw out red spiders. Plants will not be attacked by earth fleas if you sow. Radish and radish next to head lettuce, alabash and tomatoes.
Signs of defeat. It is not difficult to see whiteflies on plants. Most often, insects settle on the reverse side of the leaves, where they form fairly extensive colonies. Signs such as wilting, drying and curling of the leaves, as well as the formation of yellowish spots on the leaf plates with fuzzy outlines, indicate the defeat of seedlings by the whitefly.
Sow parsley in a tomato slice, so that you solve the problem of appearance. Brown rot on them. White mustard: inhibits the growth of weeds. In a mixture of peas, it increases the yield. The best combinations in the garden: Alabasha with red beets; Celery with tomatoes and beans; tomatoes with parsley; Beans with carrots and cabbage; Potatoes with garlic and horseradish; carrots with dill; Flavored beans; Cucumbers with peas or beans; Lettuces can grow wonderfully next to carrots.
Each situation is like a coin with two leaves. There is always a positive side! Tomatoes: symptoms and struggle. See what are the common diseases of garden tomatoes. Tomatoes are very popular vegetables grown in the ground in home gardeners. Unfortunately, they are infected with various diseases and the list is long. We suggest how to identify the most common tomato diseases and how to deal with them effectively. It is important not to grow tomatoes year after year, or near peppers or potatoes, or on a stand after these plants.
In addition, the pests release a sugary substance, which is also easily seen on damaged plant parts. Prevention measures.
In most cases, the cause of the appearance of the whitefly is the high temperature in the structure of the protected ground and the decrease in the level of air humidity. For the timely detection of the pest, it is necessary to constantly inspect the cultivated crops.
Tomatoes: potato pest
Tomatoes: tomato powdery mildew
Diseases of tomatoes: powdery mildew of tomatoes. Symptoms of tomato powdery mildew infection are seen as white streaks, initially white spots on the upper side of the leaf, which quickly blend and gradually cover the entire leaf. A white rash can also appear on the petioles and shoots of tomatoes. This tomato disease gradually moves from the bottom to the top of the plant. The spores move with the air current, infecting neighboring plants.Tomatoes: gray mold on tomato
Tomato control diseases: tomato powdery mildew. The fight begins when the first small spots are noticed on tomato leaves. Tomato disease symptoms: gray mold on tomato. The fungus most commonly affects scallops, flower stems, and leaf spots. Breeds of tomato form a gray color, gradually increasing spots, covered with a characteristic white rash. The plant often dies over the infection. Fruits and fruits themselves bend from the heel. This tomato disease contributes to long rainfall and high plant density.
Ways to fight. The easiest way to deal with adult whiteflies is to hang sticky tapes. It is best if such a tape is yellow in color. Larvae and eggs are removed by rinsing the aerial parts of plants with soapy water.
After that, the stems are wrapped in a plastic bag and left for 2-3 days. It is recommended to collect adult insects in the early morning hours, when the insects are inactive. Some gardeners collect insects with a vacuum cleaner. The most effective means of controlling insect pests (including whiteflies) are insecticidal preparations.
In particular, Fufanon, Decis, Intavir or Actellik can be used. It is also advisable to use microbiological preparations, among which Verticillin is distinguished. For the destruction of whiteflies, pyrethroid preparations are often chosen: Arrivo, Cyper-methrin, Talstar, Fury and others. Folk remedies for pest control.
You can fight the whitefly that has settled on seedlings not only by chemical methods, but also by folk remedies. It is best to use an infusion made from garlic. To do this, the cloves (2/3 cup) must be cleaned, crushed and poured with warm water (1 l). Pour the mixture into a glass dish, cork and then hold for 5 days.
The prepared infusion is diluted with clean water at the rate of 1 teaspoon of the concentrate per 1 liter of liquid and the plant affected by the insect is sprayed. To collect adults, whiteflies are often used homemade traps. To make them, you need to take a sheet of hardboard or plywood painted yellow and apply a layer of petroleum jelly, castor oil, or a mixture of rosin and honey to the surface.

Whitefly Diet
The whitefly's favorite diet primarily includes: fuchsia, begonia, balsam, passionflower, pelargonium, lantana. For lack of a favorite, the whitefly is able to attack most indoor plants. In greenhouse-greenhouse conditions, it prefers tomatoes and cucumbers, but does not disdain other plants.
Prevention
The whitefly appears where high temperature is combined with high humidity (greenhouses, greenhouses - first of all), there is not enough ventilation, the plants are placed too closely. For this reason, first of all, it is necessary to provide the plant with an optimal moisture-temperature regime and ventilation. Also, all preparations that strengthen the plant have a preventive effect - a healthy strong plant will endure the invasion of the whitefly with less losses, provided that you still defeat it!
External signs of damage
Whiteflies usually hide on the underside of leaves. On the upper side of the underlying leaves, a shiny coating (honeydew, or pad) appears - insect feces, on which sooty fungi (“black”) subsequently develop, due to which the surface of the leaf becomes first white and then black. It is soot fungi that can strongly harm the plant, not directly the whitefly. Sometimes, because of them, the growth of shoots stops.
Control measures
Chemicals:
- Actellik. Dilute the ampoule in 1 liter of water and process during the appearance of the pest. Solution consumption up to 2 liters per 10 sq.m. No more than 4 treatments. Waiting period 3 days. Verticillin G- 25 ml per 1 liter of water. Double spraying with an interval of 7-10 days. Confidor(20% WRA) 0.1 ml per 1 liter of water. Single spray. Mospilan(20% RP) - 0.05-0.06 g. Single spraying Pegasus(25% EC) - 2 ml per 1 liter of water. Double spraying with an interval of 7 days. Fufanon(57% EC) - 1.2-1.5 ml. Single spray. Phosbecid Dilute 5 ml per 5 liters of water, consumption - 100 square meters. m.
Glue traps can be used to capture adults. To do this, take pieces of plywood or hardboard, paint them yellow or white and smear them with petroleum jelly, rosin with honey or castor oil.
Insects attracted by bright yellow or white (yellow is better) sit on these baits and stick. When there are a lot of them on a piece of plywood, they wipe it and smear it again with the same solution. You can also use sticky fly traps.
Folk remedies
Whiteflies do not like low temperatures, so you can move the plant to a cooler room. Since whiteflies fly, they can be caught on sticky tapes (sold in fly-catching stores). You can use folk remedies, for example, herbal infusions against insects - they are sprayed with plants.
Relatively effective infusion of garlic. Chopped garlic cloves (150-170 g) pour 1 liter of water and insist in a tightly sealed container for five days. For spraying, 6 g of concentrate diluted in 1 liter of water is enough.
Keep in mind that folk remedies can help if there are not too many pests. Try washing the plant with clean water - whiteflies are well washed off with its water, after this procedure it is necessary to loosen the top layer of soil in the pot.
Pests on seedlings - how to recognize and fight
If measures are not taken in time, aphids, whiteflies, thrips and spider mites can destroy young seedlings. How to recognize pests and what to do if they attacked plants? You can determine who exactly harms your seedlings by the characteristic features that distinguish this or that pest.
Aphid
Insects are very voracious and multiply quickly. You can understand that aphids have settled on plants by shape change and leaf colors: they curl up And discolored. Also appears on the leaves of seedlings "honeydew"- sweet sticky secretions of aphids, which are a favorable environment for the reproduction of pathogenic fungi. Regular inspection of seedlings will help prevent the appearance of aphids, as well as the creation of optimal growing conditions:
- maintaining daytime temperatures at 20-25°C, and night temperatures at 16-20°C; regular watering with settled water at room temperature; arranging plants in such a way that their leaves do not touch each other.
If aphids nevertheless appeared on the seedlings, but there are not many of them, insects can be collected by hand, and the plants themselves can be sprayed with a solution of laundry soap (25-30 g per 1 liter of water). If there are a lot of aphids, the plants should be treated with insecticides - Inta-Vir, Decis, Kinmiks, Fitoverm, etc. (according to instructions).
thrips
Outwardly, these insects resemble miniature (about 1 mm) butterflies. They suck the juice from plants, leaving a "bite" in place. small silver spots.
Over time, these spots grow, merge and cover the entire leaf. You can cope with thrips with the help of chemical insecticides - Fitoverma, Vermitek, Akarina, etc. Moreover, you will need to carry out at least 3 sprays with an interval of 7-10 days. Tomato leaves damaged by thrips To in the future, to prevent the appearance of a pest, thoroughly disinfect containers and substrate before sowing seeds for seedlings. Also strictly observe the requirements of plants for growing conditions.
whitefly
This voracious pest feeds on the juice of seedlings, not disdaining either leaves, or stems, or cuttings of plants. By sucking the juice from the leaves, the larvae and adults of the whitefly secrete sticky enzymes, which are a favorable environment for the development of pathogenic fungi.
Damaged "seedling moth" (as the whitefly is also called) parts of plants dry up And die off.As a rule, the whitefly appears in rooms with high temperatures and low humidity. If this is not allowed - regularly ventilate the room, place wide containers of water near the plants to increase air humidity - the appearance of whiteflies can be avoided. Also, do not forget to periodically inspect the seedlings.
When a pest appears, it can be sprayed with an infusion of garlic or sticky yellow ribbons can be hung throughout the room. To prepare the infusion, pass 2 tbsp through a meat grinder. peeled garlic cloves, transfer the resulting mass to a glass jar, pour 1 liter of water and cover. After 5 days, the infusion will be ready. To spray seedlings, dilute 1 tsp. the resulting infusion in 1 liter of water.
spider mite
The spider mite is practically invisible to the human eye. It is possible to understand that the pest has settled on seedlings only when it the leaves will start to wilt And turn yellow, and on their reverse side will appear small black dots.
With severe damage to plants, leaves appear on the leaves chlorotic spots with punctate necrosis, which is clearly visible spider web.As in previous cases, it is possible to prevent mass damage to seedlings by spider mites by regularly inspecting plants and creating optimal growing conditions for them. If you notice on the underside of the leaves single black dots, try spraying the plants regularly with water.
If the pest managed to seriously "spoil" the seedlings, use insecticides - Fufanon, Chemix, Iskra M, Aktellik, Fitoverm, etc. Fitoverm is an insecticide of natural origin, which is used to combat piercing-sucking pests. The concentration of the drug solution is calculated based on which pest it is used against.
To protect seedlings from aphids, 8-12 ml of the drug is dissolved in 10 liters of water, from spider mites - 2 ml, from thrips - 20 ml. The duration of the protective action of Fitoverm is about 5 days, therefore, repeated treatments (if necessary) are carried out no later than after 7-8 days. You can avoid the appearance of most pests on seedlings if you create optimal conditions for plants.
Keep this in mind so that in the future you do not resort to the help of chemicals. Well, if you still have to use insecticides, do not forget about the precautions.
Diseases of tomatoes, on tomatoes: late blight, tobacco mosaic, whitefly
Tomato bushes are persistent and tenacious, they do not easily surrender to either infections or affectionate insects. But even poisonous leaves and stems of plants do not frighten pests.
What are the most dangerous threats to tomatoes? How can you fight them?
Phytophthora on tomatoes, tomatoes
All green parts of the plant V open ground covered with brown spots without clear boundaries and shapes. They engulf the bushes like an inevitable fire. Leaves get wet if wet, or dry out. Stems may break off.
Only ripened fruits are saved, but green and brown ones have no chance of surviving.
When phytophthora appears. Black-brown tomato plague - Phytophthora is getting younger every year - it begins to kill plants as early as July. And any geographical space is submissive to it.
The causative agent is a mushroom. It infects tomatoes and potatoes, but other nightshade plants - peppers and eggplants - do not touch.
Measures to combat late blight on tomatoes
What are the main methods of combating phytophthora. No drug is 100% effective. However, timely spraying with fungicides restrains the attack of the disease. The first treatment should be preventive: profit gold (6 g per 10 liters of water).
The second is carried out after 2-3 weeks at a dose of 15 g per 10 liters of water of both drugs.
Safe or folk remedies. Usually, folk remedies are used against phytophthora. But they are of little help.
- Infusion of garlic: take 100 g of slices, grind, pour 2 liters of water, cover, insist for half an hour and spray the tomatoes with this gruel. - Apply a yeast solution: take 100 g of yeast per 10 liters of water.
If the disease has just begun, a solution of 5% iodine (10 ml per 10 liters of water) is effective. After 3 days, the "shower" is repeated. The solution is kept closed for an unlimited time in a dark place, and it can be used to spray other plants against all fungal diseases.
Improve the resistance of tomatoes you can feed every 10 days, alternating a 1:10 solution of mullein with ash infusion (1 cup per 10 liters of water). If the leaves curl, exclude superphosphate from dressings and increase the proportion of potassium sulfate and urea.
And flowering and fruiting are delayed - they use nitrogen supplements. When the flowers fall, the bushes are sprayed with a solution boric acid(1 g per 1 liter of water), and when the ovaries fall, they are fed with a solution of mullein (1:10), adding a matchbox of ammonium nitrate or urea to it in a bucket.
Very good microbiological preparations, which are based on natural bacteria. Before planting, seedlings are sprayed with a solution of phytosporin-M or alirin-B, or they are watered with soil.
A week later, the same medicine is again well cultivated around the bushes, and then the plants themselves. Repeat the procedure every 2-3 weeks.
On tomatoes, tomatoes, tobacco mosaic virus
Tobacco mosaic virus is known worldwide. Smokers play a significant role in the spread. They throw cigarettes anywhere, do not wash their hands after smoking breaks.
The virus causes light and dark green spots in the form of "encrustation" on the leaves or dark swellings. Gray-brown areas of dead pulp appear inside the fruits. When does the tobacco mosaic virus appear?
Infection can be seen very early on already oppressed seedlings, as it persists in the seeds. The virus is also carried by the gardeners themselves during pinching. The mosaic is especially clearly visible in the summer during the milky ripeness of the fruit.
Often the leaves on the bushes become wrinkled or narrow, like a fern.
Tobacco mosaic virus control measures
Robust measures to combat tobacco mosaic virus. Seeds before sowing are kept for 20 minutes in a 1% solution of potassium permanganate. They also water plants from a young age 2-3 times at three-week intervals.
Burn all seedlings with signs of a mosaic.
Safe measures to combat tobacco mosaic virus. Most The best way- prevention. Seeds are bought only from responsible companies.
Do not plant tomatoes after peppers, eggplant, potatoes. Steam sterilize the soil and pots for seedlings, as well as all the tools that touched the plants. Wash hands with soap before work. Tomatoes are suitable only in clean clothes and shoes.
Quit smoking immediately! Or do it outside the site. Choose Virus Resistant Tomatoes tobacco mosaic.
Of the novelties, these are mainly F1 hybrids (Azov, Axioma, Almaz, Barcelona, Bogota, Buran, Bourgeois, Glamour, Caprice, Magnum M, Lezginka, Ostozhenka, Rally, Pink spam, Rosaliza, Sirtaki, Fat neighbor, Yakimanka) and the Tsarevich variety .
Whitefly on tomatoes, tomatoes
Whiteflies - these small white flies, the most dangerous pest of tomatoes. They are not found in open ground, but in winter greenhouses they sometimes completely cover tomato leaves.
When whiteflies appear on tomatoes, tomatoes. In closed ground, whiteflies can live almost all year round, but are especially numerous in the second half of summer and autumn. They hide on the underside of the leaves and suck the sap from the plants like aphids.
In addition, sooty fungi often settle on the sticky sugary secretions of the insect, which leave a black coating. It's called "black". Due to whiteflies, tomatoes can ripen unevenly and turn white from the inside.
Measures and methods of dealing with whiteflies
Reliable ways to deal with whitefly. The most effective preparations are Commander (1.5 g per 10 liters of water) and Iskra-M from whitefly caterpillars (5 ml - 1 ampoule - per 10 liters of water). They spray plants after harvesting if they want to take them to the city.
Safe ways to deal with whitefly. Ventilate the greenhouse, thoroughly wash the lower parts of the leaves with clean water, where the whitefly accumulates in in large numbers. Yellow baits are used, to which insects stick.
The biopreparation Boverin also helps. Return to the table of contents - Gardening
How to deal with whitefly?
21.03.2014 |
The whitefly butterfly brings a lot of trouble: due to the constant laying of larvae, the leaves on the plants become like a colander, they get sick and eventually die. Since each larva is covered with a waxy substance on top, chemical aerosols do not affect it in any way, the whitefly is removed only by mechanical means.
For example, in a room, a fly trap in the form of sticky tape or wiping the leaves of indoor plants with a damp cloth is suitable. Another thing is when the whitefly appeared in the garden: a one-time treatment will not work, you need to prevent the laying of eggs on the leaves and carry out prophylaxis every week.
Summer residents who water the garden with a hose have an advantage in this sense, since the larvae are not deposited on wet leaves, and this is a huge plus in the fight against insects that breed in the thousands. What can harm the whitefly?
The pest of gardens and orchards is a small insect - a whitefly butterfly. It is translucent, with a wing length of about 3 mm, something outwardly resembles a moth. It multiplies very quickly, in one day it can lay up to 280 eggs, which after 48 hours become full-fledged individuals and begin to eat borage and tomato leaves, which can cause the plant to die.
How to deal with whitefly at home?
As a solution for washing, we use yarrow, which is brewed as follows: for 1 liter. boiling water you need 80 gr. dry herbs insist in a thermos for about 2 hours. An alternative is a soap solution: 1 part laundry soap to 6 parts water.
If the whitefly started up in the garden ... How to deal with the whitefly in a greenhouse or on open area vegetable garden? Among the insecticides used: "Aktara", "Akarin", and "Phosbecid", the method of dilution with water is indicated on the package.
You need to spray every bush, some specimens can be dipped directly into the bucket. Remember that a more concentrated dose of solution is used for irrigation than for spraying. effective remedy to kill the whitefly.
It is diluted with water in a ratio of 30 ml per 1 liter. water and spray bushes. Against the whitefly on tomatoes that grow in a greenhouse, there are many ways to fight that do not damage the tomato crop. A preventive measure is to cover the windows with gauze.
On the ceiling you need to hang sticky traps. But if the invasion has occurred, it is necessary to treat each leaf of the tomato with an insecticide designed specifically for plants growing in greenhouse conditions.
If the procedure is carried out within a month (once every three days), then it will not be difficult to defeat the whitefly. Sometimes even the smell scares away butterflies, so they try to fly away from the place of processing.
It is interesting that whiteflies get used to frequently used preparations, so it is better to alternate them.
