Rosselkhoztsentr spoke about the dangerous disease of agricultural crops in the Tver region. Potatoes and tomatoes are infected with phytophthora, and cucumbers are infected with powdery mildew.
Favorable weather conditions established in the first half of July contributed to the manifestation of potato late blight. The first signs of the disease were noted on July 7 and 12 in the Bezhetsky, Rameshkovsky districts in personal subsidiary plots. The Russian Agricultural Center recommends that potato plantings be treated with fungicides. The interval between treatments in dry, hot weather should be 10-14 days, in wet, warm - no more than seven days.
Wet and warm weather also caused the spread of diseases of tomatoes and cucumbers. The branch of FSBI Rosselkhoztsentr in the Tver Region warns of the widespread widespread spread of downy mildew (peronosporosis) on cucumbers, as well as brown leaf spot, alternariosis, late blight on tomatoes.
To reduce the severity of diseases, experts recommend observing the optimal temperature and humidity conditions for plant development, feeding and treating with fungicides when the first signs of disease appear. Fruit harvesting is recommended with mandatory observance of the waiting time: in closed ground for three days, in open ground for five days.
