Abstract: Abstract：Atrazine is a triazine herbicide，which can control annual monocotyledon and dicotyledon weeds，and also inhibit certain perennial weeds．It is one of the most important herbicides for corn production in the world．It can also be used in sorghum，sugarcane，fruit trees，etc．It is moderately persistent in the environment and can remain in the atmosphere，water，and soil environment．It is easy to cause different degrees of pesticide damage to subsequent crops such as rape，Chinese cabbage，fi eld mustard，cucumber，pepper，cowpea，and okra．At the same time，it causes harm to natural ecosystems and human health．This paper reviewed the microbial degradation of atrazine；introduced the microbial degradation techniques of herbicide atrazine from 3 aspects，including bioaugmentation，biostimulation，and immobilization；compiled and summarized the microbial groups being confi rmed in previous studies；clarifi ed the microbial degradationmechanism of atrazine from 2 aspects：degradation process and degradation genes；analyzed the factors affecting the microbial degradation of atrazine and prospected the future research direction．
