The application of herbicides has brought convenience to agricultural production,but long-term use of single herbicide or herbicides with the same mode of action has caused the problem of weed resistance to herbicides.The types of resistant weeds keep increasing,and the formation mechanism of resistance is complex,which leads to the difficulty in the control of weeds in farmlands.The resistance mechanisms of weeds to herbicides are mainly divided into two types.One is target resistance caused by mutations or overexpression of herbicide-targeted genes,and the other is non-target resistance caused by changes in one or more physiological processes such as herbicide uptake,transport,sequestration,and metabolism.In this review,the physiological,biochemical and molecular bases of non-target resistance mechanisms of weeds to nine kinds of herbicides with different action modes were summarized to provide a reference for the comprehensive management of resistant weeds.
