EFFICIENCY OF USING HERBICIDES ON SPRING BARLEY PLANTINGS
The article presents an assessment of the effectiveness of the use of herbicides on spring barley plantings against annual dicotyledonous and some perennial offset weeds in the central irrigated natural-agricultural zone of the Rostov region. The structure of the weedy component of spring barley plantings was studied in the experiment, and the indicators of yield formula and quality of spring barley grain were determined. Summarizing the results of the studies carried out, it is recommended to spray spring barley plantings in the tillering phase with the herbicide Ballerina, SE with a consumption rate of a technical preparation of 0.5 l/ha. In this variant of the experiment, the greatest biological effectiveness of the herbicide against annual dicotyledonous and some perennial offset weeds, better indicators of grain quality and crop productivity, as well as higher indicators of economic and energy efficiency are noted. The herbicide Secator Turbo is also highly effective, however, it is not recommended to grow crops sensitive to sulfonylureas after the crops on which this herbicide was applied.
