Abstract

 

Winter rapeseed is a strategically important oilseed crop, occupying more than 32 million hectares in the world. In Kazakhstan, over the past five years, the average yield was 12.2 c/ha with a bulk yield of 172 thousand tons. The crop has high potential due to its oil content (45–50%) and protein (20–25%), but requires effective protection from weeds, which can reduce yields by 25–30%. During a three-year study (2021–2023), the effectiveness of using herbicides against cereal (Zellek Super, Pantera, Selekt) and dicotyledon plants (Lontrel 300 and Khaker) weeds was studied.  The assessment  was carried out based on indicators of biological effectiveness, crop infestation, and yield. The use of herbicides increased the yield from 9.5–11.8 c/ha in the control to 17.9–30.2 c/ha in the treated areas. The preparations “Zellek Super” and “Pantera” (0.75–1.5 l/ha) showed the greatest efficiency against cereal weeds, reducing weed infestation by 95–97%. Optimal results were obtained when using the herbicide “Lontrel 300” (0.4 l/ha) against dicotyledon plants. Recommendations were developed for the use of tank mixtures taking into account the species composition of weeds (barn grass, wild oat, cocklebur, pigweed). The results obtained for these herbicides can be used on winter rape crops and achieve effective weed control.
