Phytosanitary control of mixed crops of the Kaliningrad region

Abstract

The paper analyzes the potential hazards in the cultivation of mixed crops of spring and winter legume-cereal crops without the use of herbicides and phytosanitary basics of their use in the conditions of the Kaliningrad region are formulated. It has been established that the joint cultivation of legumes and grain crops leads to an increase in the assimilation surface and photo potential of cenoses by37-79%. It was shown that, on average, pure sowings of narrow-leaved lupine plants were affected by anthracnose more strongly than its mixtures with grain crops, although the difference between single-species and mixed sowings is relatively small, it was 2.7-4.5% for narrow-leaved lupine. In order to avoid mass contamination by main weeds, it is recommended to use well-cultivated fields with late summer treatment with glyphosate-containing herbicides of continuous action. During the main processing under mixed legume-cereal crops, the best method of tillage is the alternation of soilless tillage with plowing.
