The appearance and spread of herbicide-resistant weeds biotypes leads to a decrease in the effectiveness of protection, yield losses and threatens to increase the pesticide pressure on agrophytocenoses. The main means of preventing the emergence of resistance in weeds is the complex application of herbicides with different mechanisms of phytotoxicity. Herbicidal compositions aimed at combating resistance are significantly different from traditional herbicide complexes, the main purpose of which is to increase the effectiveness of crop protection by expanding the spectrum of controlled weed species. The main problem in creating anti-resistant compositions of herbicides is the need to ensure the synergistic or additive nature of their components interaction. As a result of the conducted research, combinations characterized by synergistic or additive interaction were determined. Based on the obtained results, recommendations were developed for the complex herbicides application for the effective protection of crops of winter wheat, maize, winter rape and sunflower, as well as the prevention of the emergence and spread of herbicide-resistant weed biotypes.
