The mechanisms and factors that influence the evolution of herbicide resistance in weeds are reviewed along with the weed control practices available for the control of herbicide- resistant weeds. Weed resistance to herbicides can be of two types,namely target- site resistance that includes the alteration of the site of action,gene amplification and overexpression,and non- target- site resistance that includes enhancement of metabolic detoxification,limited uptake and translocation,and compartmentalization. The evolution of weed resistance is influenced by many factors,such as resistance mutation frequency,herbicide selective pressure,weed fitness and weed seed bank life. Additionally,gene mutation and genetic characteristics are directly related to its evolution. It is advisable to investigate and identify resistant weeds in fields regularly,apply herbicides properly( with rotation or mixture of active ingredients),and to integrate agronomic management practices to prevent evolution of weed resistance to herbicides in the future. Additionally,fundamental research on allelopathy in plants should be emphasized for providing theoretical bases for developing safer herbicides.
