抗草甘膦杂草的抗性机理研究进展

Advances on Resistance Mechanism of Glyphosate-Resistant Weeds

草甘膦因其独特而优异的理化特性,自上市起便受到广泛的关注,现在已经成为全世界应用最广的除草剂之一。但是随着草甘膦抗性杂草的不断出现,草甘膦的应用前景受到严峻的挑战。文章综述了草甘膦生产及应用现状、草甘膦作用机理和草甘膦抗性杂草的发展,重点阐述了草甘膦抗性杂草的抗性机理。最后对如何通过延缓草甘膦抗性杂草的出现,保护草甘膦提出建议。

Glyphosate, because of its unique and excellent physical and chemical properties, has attracted much attention since it was commercialized. At present, gtyphosate has become one of the most widely used herbicide around the world. But with the emergence of glyphosate -resistant weeds population, the application prospect of glyphosate has been seriously challenged. In this paper it was reviewed in the production and application status, the mechanism of action of glyphosate and the development of glyphosate - resistant weeds especially focused on introduction of the resistance mechanism of glyphosate - resistant weeds. Finally, how to delay the emergence of glyphosate - resistant weeds to protect the application of glyphosate has been also proposed in this paper.
