Viral disease, recognized by characteristic spots on the leaves. Light green blotches are located near the veins, with time they grow and merge. In the late stage, the midpoint of the hearth darkens and dies off. Underdeveloped fruits with low taste qualities are formed on the affected bushes.

As a preventive measure, spraying the bed 1 time in 10 days with a milky solution (1 l of milk and 20 grams of grated soap) is carried out. Not less effective are: Fitosporin and Uniflor-micro.

When a mosaic is found, it is necessary to sanitize the entire inventory so as not to infect healthy plants. Patients shoots need to be disposed of by burning.

White rot

Fungal disease that occurs mainly due to excess moisture in the air and soil. The reason may also be covered in cold weather when planting seedlings. The fungus infects the root system of eggplant, resulting in a whitish plaque on the stem. Disturbance of nutrient intake and developing microorganisms lead to the death of a shoot.

As a preventive measure, it is recommended that one time in 10 days be used to powder a bed of wood ash or chopped chalk. If any lesions are found, remove them and dispose of them.

What to do with gray mold

Recognized by the characteristic dark watery spots that cover the leaves, the stem and even the fruit. The ideal environment for the development of a fungal infection is heat (+ 20 ° C) and high humidity (air and soil). Spores persist in the ground for 2 years, infecting subsequent crops, so it is important to carefully harvest plant waste from the garden and disinfect.

Sores covered with vegetables become unusable. The disease is rapidly developing at high humidity and a temperature of about + 30 ° C. The source of infection can be both seeds and soil, so disinfection is carried out before planting.

Insect pests can also significantly reduce yields. The danger is that the larvae and the parasites themselves easily survive the winter in plant debris and soil. Experienced gardeners, for good reason, advise to disinfect all seed and soil before planting. By spending a minimum amount of time and money on preparation, it is possible to avoid infection of young shoots and ripening fruits.

How to get rid of aphids

The population of parasites is increasing at an incredible rate, so you should not postpone processing. You can recognize the problem by the withered bush species, twisted leaves, fallen ovaries.


  • choice for planting illuminated and well-ventilated area;
  • soil moisture adjustment;
  • disinfection of seeds and soil before planting;
  • weed control;
  • removal of affected leaves.

Control measures

With the rapid detection of aphids in the greenhouse you can spray planting infusion of onion peel (tobacco dust, potato tops). If the affected area is significant enough, special preparations are indispensable (Akarin, Fitoverm).

Treatment with insecticides is permissible only before the flowering of the crop. During the fruiting period, toxins will be absorbed into the fetus, which can be harmful to human health.
