More unprotected fruits are still unripe fruits of the second and third brushes, and the first manifestations of the disease are dark green spots, which, as the disease progresses, acquire a brownish or blackish color. These formations appear at the top of the fetus.
The disease blocks the fetus's ability to grow and regain its normal shape. When the top of a tomato is completely devoid of moisture, the skin on it cracks, which allows the disease to spread safely further. Rotten tops are a favorable environment for Alternaria fungi, which, in turn, also affect the quality of the fruit.
Already "diseased" tomatoes ripen earlier than usual, but it is impossible to use them as food and collect seeds from them.

In a three percent solution of potassium permanganate, the seeds are kept for half an hour. Then they are washed with warm water and dried. Also, use one gram of ferrous sulfate per liter of water. Future tomatoes are kept in such a solution for about a day, and then dried.
It is necessary to stratify the soil.

Treatment is to make up for the calcium deficiency.
Use calcium nitrate or potassium chloride.
And to improve the quality of treatment, you can use boric acid or the drug "Brexil Ca" together with calcium.
Irrigation is carried out at intervals of ten days or half a month.
