Progress in microbial degradation of typical imidazolinone herbicides

Imidazolinone herbicides are widely used in China. Their advantages include wide herbicide spectrum, high activity and strong selectivity, but the pesticide remains in soil for a long time. In this paper, the effects of typical imidazolinone herbicides (imazamox, imazethapyr and imazapic) residues on succeeding crops, and investigated the microbial groups and degradation pathways of partially imidazolinone herbicides (imazamox, imazethapyr and imazapyr), the factors affecting the degradation of imidazolinone herbicides by microorganisms were analyzed. The existing problems and prospects for herbicide remediation were pointed out. It is helpful for the study on the microbial degraders of imidazolinone herbicides.
