Diseases and pests began to appear progressively on winter crops. This is caused by prolonged low temperatures at night and sharp drops in the daytime, and the precipitation that occurred the other day, said an expert on agri-environmental issues, Alexei Sergienko. This was reported by main magazine on agribusiness Proposition .
Powdery mildew (Erysiphe graminis DC. F. Tritici Em.Marchal), leaf septoria (Septoria tritici Rob.et Desm.), Fusarium wilt (Fusarium graminearum, Fusarium sporotrichiella), pyrenophora (Pyrenophora tritici) have already been observed on winter wheat. Cereal flies (Phorbia secures) began to fly en masse.
Farmers begin to treat wheat fields with fungicides, insecticides, herbicides. It is worth remembering that preventive crop protection measures are always the most effective and efficient. Experts advise to use fungicides approved for use in Ukraine, from different classes and with different effects on the complex of pathogens (triazoles, strobilurins, carboxamides, etc.). Pyrethroid drugs can protect crops from sucking pests (flies, aphids, cicadas), which not only affect the crop, but also carry a variety of viruses.
