Research progress in microbial degradation of triketone herbicides

Abstract:

Triketone herbicides with high efficiency, broad spectrum, and high selectivity can effectively control a variety of broadleaf weeds and gramineous weeds in maize fields. The residues of the herbicides in soil and water are easy to cause surface and ground water pollution. Studies have indicated that microbial degradation is expected to be an effective measure to solve herbicide residues. In this paper, we analyzed the ecological effects of two triketone herbicides, summarized the reported microbial resources for residue degradation, and briefed the research progress in the degradation genes/enzymes and possible degradation ways, aiming to provide information support for further research on the biodegradation of triketone herbicides.
