One of the most common ailments that affects tomatoes is blight. This most dangerous disease is sometimes characterized as the plague and cancer of tomatoes.
It occurs mainly due to lack of sunlight and excessive humidity. The fungus infects the leaves first, and then the whole plant. In advanced cases, the bushes die.
Experts believe that such a massive spread of the disease is due to the fact that southern varieties of tomatoes are grown in not very suitable climatic conditions.
Naturally, there are a lot of agrotechnical methods, chemicals for seed treatment, seedling, seedlings and mature plants, through which the disease can be prevented. But the most important thing is that the varieties of tomatoes that are resistant to late blight are bred.
Instead of fighting the disease, it is much better to prevent it, and planting plants that are not susceptible to illness, is the best preventive measure.
The peak of the surge of this disease is considered to be the second half of the summer, because just at this period prolonged rains begin, thick fog and dew fall out, and the sun is getting smaller, - all this creates favorable conditions for the development of harmful fungal spores.
