Effectiveness of herbicides in the destruction of weeds and carrion of spring rapeseed in the link of the crop rotation of spring rapeseed - spring wheat in the conditions of the Tula region

Studies conducted in the production conditions of the Tula region have shown that the cultivation of spring wheat after spring rapeseed using technologies without the use of dump plowing at the early stages of crop development leads to a problem with the fall of spring rapeseed. As a weed, it rises simultaneously or earlier than spring wheat, develops faster, competing with the crop for nutrients, soil moisture and light. The task of the research was to determine the optimal timing of the use of various herbicides and their tank mixtures in order to destroy weeds and, above all, rapeseed carrion. It has been found that their use is more effective in the middle of the tillering phase of spring wheat, as this avoids the negative effects of drugs on the culture, effectively destroying weeds and rapeseed carrion. The use of herbicides in the middle of the tillering phase of the crop led to an increase in the yield of spring wheat by 0.33 - 0.48 t/ha compared with the control variant.
