Tomato varieties for greenhouses that are resistant to late blight will help protect the crop from complete destruction. Late blight is the most common fungal disease among tomatoes. The disease is spreading at incredible speed. There are many ways to combat the disease, but it is easier to prevent the problem.
Popular varieties for open beds
The causative agent of late blight is a fungus that affects not only tomatoes, but also other vegetable crops of the nightshade family.
It is not always possible to detect the first signs of the disease, since the inside of the leaves is affected and a whitish coating appears.

A dark seal first appears on the tomatoes, which grows every day, and as a result, the entire fruit darkens and begins to smell unpleasant.
