摘　　要：五氟磺草胺是一种乙酰乳酸合成酶抑制剂类除草剂。为探明稻田稗草对五氟磺草胺的抗性现状,采用整株生物测定法测定了采自中国7省70地稻区的稗草田间种群对五氟磺草胺的抗性。结果表明:所监测的稗草种群对五氟磺草胺均产生了不同程度的抗性,其中高水平抗性种群达50.0%,中水平抗性种群达47.1%,低水平抗性种群为2.9%,无敏感种群。在湖北、安徽、宁夏和黑龙江4省中,高水平抗性种群均达60%以上;其他3省的高水平抗性种群也在25%以上。湖南、江西和江苏3省中等水平抗性种群均在60%以上,其他4个省份在20.0%~40.0%之间。湖北省和黑龙江省低水平抗性种群分别为10.0%和12.5%,其他5个省份均无低水平抗性种群。本研究揭示了中国主要稻区稗草田间种群对五氟磺草胺的抗性现状,可为合理应用五氟磺草胺防控稻田稗草提供理论依据。Penoxsulam is a new acetolactate synthase inhibitor(ALS)herbicide developed by Dow AgroSciences.In order to explore the sensitivity of Echinochloa spp.to penoxsulam on rice field,whole-plant bioassay experiments were conducted to evaluate the resistance level of 70 field populations of Echinochloa spp.from main rice production in seven provinces of China.The results showed that 50.0%of the 70 populations had evolved high resistance,47.1%of the populations was moderate resistance,and only 2.9%of the populations exhibited low resistance.None populations were sensitive to penoxsulam.More than 60%of the populations had evolved high resistance from Hubei,Anhui,Ningxia and Heilongjiang Province.The populations of high level resistance was more than 25%in other three province.More than 60%of the population with moderate level resistance were from Hunan,Jiangxi and Jiangsu Province,and the populations of 20.0%-40.0%were also with moderate level resistance in others 4 provinces.The 10.0%and 12.5%of population were with low level resistance in Hubei and Heilongjiang Province,while other 5 provinces had no low level resistant populations.This work investigated the evaluation and monitoring of the field resistance of populations of Echinochloa spp.to penoxsulam,which provided a theoretical basis for the scientific application of penoxsulam to control Echinochloa spp.in the main rice cultivation area.
