A report on the phytosanitary status of winter crops has been published

04/04/2023 09:35

Sharp fluctuations in night and day temperatures during the third decade of March, rain and wet snow, and morning frosts restrained the development and spread of harmful organisms in winter grain and rapeseed crops. This is stated in the notification of the State Production and Consumer Service.

At the same time, in Dnipropetrovsk, Zaporizhia, Kirovohrad, Mykolaiv, Odesa, Poltava, and Cherkasy regions, the feeding of mealybug larvae continues in winter. The pest damaged 2-6% of plants (local cells).

During the cool weather of the reporting period, grain fleas and leafhoppers sluggishly inhabited and damaged crops of winter cereals. In the southern and central regions, caterpillars of older ages of the winter weevil feed. In the Steppe, on 3-35% of the examined areas of winter crops, mainly from the edges of the fields, up to 2% of the plants were damaged by the sand midge.

In the Steppe, the harmful turtle bug is found in wintering places. In the future, as the leaf litter warms up to 10-12ºС, bugs will move to its surface everywhere. Currently, an early onset of phytophagous colonization of crops is predicted.

Everywhere on 4-32% of the surveyed areas of winter wheat, barley, and rye plants are affected by powdery mildew and septoriosis (Kyiv region), 2-6% of plants by helminthsporiosis and brown leaf rust, 2-7% of plants by root rot. In the Lviv and Ternopil regions, snow mold develops on 2-15% of physiologically weakened plants, especially in places with low terrain.

Winter rapeseed plants are inhabited and slightly damaged by nymphs (stem rapeseed, large rapeseed), in some places sand midge, cabbage moth, rape leafhopper. In the farms of Dnipropetrovsk, Zaporizhzhya, Kyiv, Lviv, Mykolaiv, Odesa and Cherkasy regions, 1-4% are damaged by cruciferous fleas.

On 4-42% of surveyed rapeseed areas, 10-15% of plants (Zhytomyr, Kyiv, Cherkasy regions) suffer from downy mildew, alternaria, fomosis, snow mold, white spot, root bacteriosis.

In the farms of the Mykolaiv region, winter pea crops are inhabited by sand copper beetles, bulbous weevils, which damaged to a weak degree up to 1% of plants on 10-20% of the surveyed areas.
