Abstract

Due to single and the frequent application of herbicides, the resistance of Amaranthus retroflexis is constantly evolving. This paper reviews the research progress and research methods of the resistance mechanism of Amaranthus retroflexis L. in recent years. The mechanism of action of Non-target-site resistance (NTSR) is usually more complex than that of target resistance (TSR), and to herbicides with dissimilar modes of action it can produce cross-resistance. In addition, the effects of Amaranthus retroflexis on the mutation of different herbicide targets and the alteration and selection of NTSR by P450 enzyme inhibitors are also discussed. Understanding the prevalence of resistance mechanisms in Amaranthus retroflexis and the coexistence of TSR and NTSR will be critical for designing sustainable weed management strategies to prevent further evolution and selection of Amaranthus retroflexis resistance to herbicides.
