摘　　要：为了掌握四川省稻田稗属杂草对二氯喹啉酸的抗药性,采用整株生物测定法测定了四川省稻田20个稗属杂草种群对二氯喹啉酸的敏感性,明确其抗药性水平。结果表明,10个种群仍处于敏感或敏感下降阶段;9个种群对二氯喹啉酸产生了不同程度的抗药性,其中6个种群为低抗,3个种群为中等抗性。供试种群中近50%对二氯喹啉酸产生了抗药性,但多为低抗或中等抗性,抗药性水平总体不高。In order to understand the resistance of barnyard Echinochloa grass to quinclorac in rice fields of Sichuan province.Whole plant bioassay was conducted to determine the sensibility of twenty barnyard grass populations to quinclorac and to quantify their resistance level.The results showed that ten populations were still in a sensitive or sensitive decline stage.Nine populations produced different degrees of resistance to quinclorac,of which six populations were low resistant and three populations were medium resistant.Nearly 50% of the tested barnyard grass populations were resistant to quinclorac,most of which were low resistant or medium resistant.The resistance level was generally low.
