摘　　要：本研究旨在评估江苏稻田中稗草对四种不同除草剂的抗药性。通过2019—2022年从江苏省稻田采集稗草种子,并采用茎叶喷雾法分别测定了不同稗草种群对噁唑酰草胺、氰氟草酯、五氟磺草胺和二氯喹啉酸的抗药性。采集到的100个稗草种群用鉴别剂量法筛选出对不同除草剂的疑似抗性种群,再用不同除草剂的系列浓度药液测定这些疑似抗性种群对相应除草剂的抗性指数。测定结果表明,对噁唑酰草胺表现低抗性种群、中抗性种群和高抗性种群分别为10、8、1个;对氰氟草酯表现低抗、中抗种群各5个种群;对五氟磺草胺表现低抗、中抗和高抗种群分别为3、9、1个种群;对二氯喹啉酸表现低抗、中抗和高抗种群分别为1、7、1个种群。所测稗草种群在江苏地区13个地级市中除常州市外,均有抗性种群分布,部分地区的稗草种群表现出多抗性。In order to further understand the herbicide resistance of barnyard grass[Echinochloa crus-galli(L.)P.Beauv.]in Jiangsu rice field,the seeds of barnyard grass populations were collected from rice fields in Jiangsu Province from 2019 to 2022,and the resistance of barnyard grass species to metamifop,cyhalofop-butyl,penoxsulam and quinclorac was determined by stem and leaf spray method.The suspected resistant populations of 100 collected barnyard grass populations were screened by differential dose method,and then the resistance index of these suspected resistant populations to the corresponding herbicides was determined by the series concentration of different herbicides.The results showed that there were 10 populations with low resistance,8 populations with medium resistance and 1 population with high resistance to metamifop;there were 5 populations with low and medium resistance to cyhalofop-butyl;there were 3,9 and 1 with low,medium and high resistance to penoxsulam,respectively;there were 1,7 and 1 with low,medium and high resistance to quinclorac,respectively.The tested barnyard grass populations in 13 prefectural level cities in Jiangsu Province,except Changzhou,all have resistant population distribution,and some populations show multiple resistances.
