Abstract: Sulfonylurea herbicides are featured by high efficiency, broad spectrum, and high selectivity. They have caused serious damage to the environment after widely used in long term. The elimination of environmental problems caused by the use of sulfonylurea herbicides is one of the important issues in modern agriculture. The main degradation methods of sulfonylurea herbicide include chemical degradation and biological degradation. Biological degradation is a natural way to degrade pollutants with high feasibility and low side effects. In recent years, many studies have examined the role of fungi, bacteria and other microorganisms in degrading sulfonylurea herbicides, with many important results being achieved. We summarized the properties, structure and degradation mechanism of sulfonylurea herbicides, and the variety of microorganisms capable of degrading herbicides, and the factors affecting the efficiency of microbial degradation. Finally, we proposed the problems and the development trend of sulfonylurea herbicides in the future.
