| Abstract | Considering the tendencies of climatic conditions change, autumn application of herbicides while growing winter wheat is an important factor of weed control. Combined application of the agents Lancelot (0.033 kg/ha)+Pallas (0.15 l/ha) in the phase of BBCH 13 of wheat contributes to a perfect control for loose silky-bent and dicotyledon weeds, as well as support for the yield by almost 30%. Spraying of wheat with a tank mixture of Tru (0.02 kg/ha)+Stomp (2.5 l/ha) makes no sufficient effect on loose silky-bent. All combinations of those herbicides reduced the weed mass before harvesting. Under application of Lancelot+Pallas and Marathon, it accounted for only 13.6 and 15.1 g/m2 respectively, and biological efficiency – 93.2 and 92.2 %. Autumn application of the herbicides contributed to increase of wheat yield capacity by 1.50-1.73 t/ha, or 25.7-29.6 %. | ||
