Variation in mutations providing resistance to acetohydroxyacid synthase inhibitors in Cyperus difformis in China.

Pesticide biochemistry and physiology - 1 Jun 2020

Abstract excerpt

Cyperus difformis has evolved resistance to pyrazosulfuron-ethyl and other acetohydroxyacid synthase (AHAS) inhibitors in paddy fields in China. To understand the distribution of resistance and the mutations involved, 38 populations collected were from 7 provinces and compared. Application of pyrazosulfuron-ethyl at 30 g a.i. ha-1 identified 16 populations that survived, demonstrating resistance to this...
