The threat of the development of murine rodents in the fields persists under stable weather conditions.

In the Kharkiv region, rodent infestations were detected in all surveyed areas of winter wheat and sunflower fields, with a density of 1.0-2 colonies per hectare. They were also found in uncultivated lands in all surveyed areas, with a density of 1.3-3 colonies per hectare. This is reported by the State Consumer Service regarding the phytosanitary condition of agricultural crops. Currently, the development of rodents is being restrained by periodic thaws, ice and freezing of melted water in the fields and burrows. Their further development will largely be determined by weather conditions, in particular, stable air temperature, a prolonged period without snow cover, or the presence of stable snow cover will contribute to the life activity of rodents. Additionally, the migration of rodents to winter cereals, winter rapeseed, and perennial grasses and an increase in their numbers on these crops is possible in the future. It is important to systematically survey winter crops, ...
