During the third decade of April 2022, the development of agricultural crops took place mainly under difficult agrometeorological conditions. Cool long spring delays the mass population of crops with pests, and also does not contribute to the significant development of diseases. This was reported by Derzhprodspozhyvsluzhba.
In the reporting period, the decrease in air temperature both at night and during the day did not contribute to the active flight of the bedbug of the harmful turtle in the fields. The bedbug harmful turtle is in a satisfactory physiological condition. In the future, with the onset of stable warm weather with average daily temperatures of 12-14 ° C, max. 18-20 ° С, it is necessary to expect active flight of a phytophage on the area of winter cultures. Males are the first to wake up and fly to the crops, and females – for 5-7 days later, depending on the weather. Damage to plants by bedbugs in the tillering phase causes yellowing and death of the central leaf, at the beginning of the plants in the tube – the death of the central stem. Settlement of crops by the pest will be stretched over time, this is facilitated by sharp fluctuations in air temperature.
Everywhere there is a disease of winter wheat, barley and rye on powdery mildew, septoria, helminthosporiosis, red-brown, other spots, brown leaf rust, root rot, sometimes rhinosporiosis, which covered 10-25, max. 51 and 87% of the area (septoria, centers in Kirovohrad and Lviv regions), 0.5–12% of plants on early well-developed crops were affected. Disease development was not detected in spring crops. Rehabilitate crops during the emergence of plants in the tube at an intensity of 1% spotting, leaf septoria 5% due to spraying with appropriate fungicides.
Garden weevils are harmful in orchards, inhabiting 3–22% of trees and damaging 1–5% of buds and leafhoppers. .
Farms carry out constant phytosanitarian supervision over crops.
