Tomatoes most often spoil the whitefly and scoop. Wet and warm weather is ideal for pest breeding. The proximity of courgettes, eggplants, peppers and fruit trees also has a negative impact. Both pests are most harmful to plantings located in open ground.
Organic ways to get rid of pests
If a caterpillar has attacked the tomatoes, and the plant already has ovaries, then biological insecticides should be used.
With these means, you can safely spray tomato bushes on which there are already fruits. These drugs include:
- "Lepidocide"
- Fitoverm,
- "Aktofit",
- "Admiral",
- "Aktara" and others.
They are removed from plants in 2 weeks. Their disadvantage is that the caterpillars can get used to them.
Chemicals
First of all, pesticides of 1-3 hazard class will help get rid of pests. Insects will be destroyed with 100% probability. But heavy chemicals are allowed to be used only during the flowering stage. The term for removing substances from tomatoes is up to 30 days.
Among the effective means:
- "Avant";
- Inta-Vir.
Both drugs eliminate insects at any stage. For processing, the seedlings are first sprayed, and then the procedure is repeated two weeks later. The drugs "Zeta", "Arrivo", "Decis", "Tsitkor" are used in the same way.
Folk remedies
Available home methods can be used to treat tomatoes from caterpillars. They are effective if there are not too many insects. Chopped potato tops should be steamed in a 1 to 10 ratio. The tool is infused for up to two days, after which you need to add a quarter of a bar of grated laundry soap. Tomatoes should be sprinkled with this mixture twice a day with morning and evening watering.
One head of garlic can be chopped and filled with a liter of boiling water. The solution is allowed to settle for three days. Next, add half a glass to soapy water.
Wormwood should be finely chopped, filled with a third of the bucket and filled with cold water. Further, the agent is boiled for half an hour and insisted for two days.
In addition to these funds, you can use a strong salt solution. A pack of table salt is used for 3 liters of water. The solution is used to process tomato beds.
Preventive measures
In the autumn, you need to dig up the soil on the bayonet of the shovel. Large parts of the land do not need to be broken. In the springtime, domestication is carried out again, but the earth is additionally loosened.
To get rid of insects, you should water future beds in the fall with boiling water and potassium permanganate. Once again, this procedure is carried out in the spring.
