Over the past week, in the field protection zones of the Chuguiv district, the awakening and appearance of adult bugs of the harmful beetle on the surface of the forest litter continued at a number of 0.5-1 specimens per sq. m, and in the winter grain crops of the Lozov district, the beginning of the spread of bugs was noted at a number of 0.3-1 specimens per sq. m. In the future, the migration of this pest to the crops of winter and spring grain eared crops will continue in all districts. First, in the southern regions of the region, and then in other districts, the beginning of egg-laying by the phytophagous is expected within the next one to two weeks. Damage to the stems by bugs during the piping of winter crops and tillering of spring crops leads to their death, and before earing causes complete or partial whiteness and fragility of the grain.
Also, the spread and development of diseases continues in winter wheat crops, namely: septoria leaf spot, powdery mildew, and root rot affecting 2-5% plants. In the future, frequent precipitation and moderate temperatures may contribute to an increase in the prevalence and harmfulness of the above and other diseases.
Agricultural producers are recommended to constantly monitor the phytosanitary condition of winter and spring grain crops and, if the economic threshold of harmfulness of the harmful beetle bug is exceeded (2-4 or more overwintered bugs per sq. m during the emergence of winter grain crops into the tube and 3-4 specimens per sq. m of spring barley in the tillering-outerment phase), take measures to carry out timely chemical treatments with insecticides and fungicides permitted for use to limit the spread of the disease complex, adhering to the regulations for their use and ensuring the preservation of beneficial entomofauna and honey bees.
