How to make the treatment of tomato macrosporiosis effective - we find out the causes, symptoms and measures to combat the disease
Some fungal diseases are dangerous because they affect plants, including tomatoes, at any stage of their development, for example, macrosporiosis. Treatment of macrosporiosis of tomatoes should be started at the first detection of a bush lesion. If you miss the moment, then in a couple of weeks the fungus will completely destroy the plant along with the harvest. Stems, leaves, fruits - everything is a breeding ground for gluttonous fungi. Moreover, having fallen on the soil together with dead vegetation, they winter safely in it. And next season, the plantings of nightshade crops are attacked with renewed vigor.
How does macrosporiosis manifest on tomatoes
The main cause of the disease is fungal infection of plants or soil. Spores can be brought in by the wind, or brought along with inventory or shoes. In the presence of the slightest damage (wounds, cracks), fungi penetrate the plant and begin to multiply. They are especially comfortable if summers are hot and humid, or with abundant night dew.
Signs of macrosporiosis:
- first, the fungus affects the lower leaves - dry dark spots appear on them below;
- gradually the affected area passes to the stems and upper leaves, which dry up and die off;
- the fruits are the last to suffer - they also show almost black dry spots that have grown into the flesh;
- after sporulation, dry spots are covered with new spores - a velvety dark bloom.

The best effect will be given by the use of special preparations, and already at an early stage. Against fungal disease, seedlings and adult plants are sprayed:
- oxychloride (0.4%);
- Bordeaux liquid (1%);
- Tsinebom (0.4%);
- Ridomil;
- Polychoma.
Fungicide treatment is applied up to 4 times, but only before harvesting. The last spraying can be carried out no later than 3 weeks before. And in the fall, it is imperative to treat the area where the infected tomatoes grew with copper sulfate. Otherwise, the fungus will remain in the ground.
