摘要：The paper considers the issues of the effectiveness of the integrated use of pesticides on crops of spring rape hybrids and their impact on crop productivity in the conditions of the Krasnoyarsk forest-steppe. The increase in the production of oilseed rape is primarily due to the use of intensive technologies in agriculture due to the limited sown area. The biological characteristics of spring rape require special attention to the means used to protect the culture from harmful organisms. The effect of insecticides, herbicides and fungicides of the "August" Company on the crop structure of 12 rapeseed hybrids was studied, and the biological and economic efficiency of their use was evaluated. The natural and climatic conditions of 2019 contributed to an increase in the number and variety of harmful organisms such as pests and weeds, so the role of the use of "August" Company drugs in the integrated protection of spring rape hybrids has increased. During the study, it was found that the combination of the use of Break, ME and Borey Neo, SK insecticides in pest control reduced their spread and harmfulness in all variants of the experiment to almost zero. The use of the fungicide Kolosal Pro, KME, led to the cleanliness of rapeseed plants from diseases. The highest level of profitability for KL hybrids was in the variant of the combined use of the Paradox, VRK + Grader VGR herbicides, respectively, in hybrids of the Halion and Estock herbicides that are unstable to imidazolinones.
