摘要/Abstract

摘要： 为明确安徽省稻田稗草对五氟磺草胺的抗性水平及分布现状，采用整株生物测定法测定了采集自安徽省不同地区稻田的 40 份稗草对五氟磺草胺的抗性，并筛选出抗性水平最高的抗性生物型测定其对 15 种除草剂的敏感性。结果表明，安徽地区稻田稗草已对五氟磺草胺产生不同程度的抗药性，所测样本中，抗性种群 20 个，占总样本数的 50%，其中，中、高抗种群 13 个，占总样本数的 31. 5%。沿江平原地区和江淮丘陵区采集点的稗草对五氟磺草胺的抗性水平较高，其次为皖南山区，淮北平原区和大别山区稗草对五氟磺草胺的抗性水平则相对较低。抗性种群 R 对嗪吡嘧磺隆、双草醚、二氯喹啉酸、氰氟草酯、三唑磺草酮产生抗药性，对双唑草腈、噁草酮、禾草丹、莎稗磷、噁唑酰草胺的敏感性较低，对丙草胺、丁草胺、二甲戊灵、仲丁灵、敌稗表现敏感。

Abstract: In order to detect the resistance level of Echinochloa crus-galli（E. crus-galli） from rice fields to penoxsulam in Anhui province and its distribution，whole-plant bioassay experiments were conducted to evaluate the resistance level of 40 populations of E. crusgalli from rice fields in different areas of Anhui province. Additionally，the resistant biotype with the highest resistance level was tested for sensitivity to 15 herbicides. The results showed that E. crus-galli in Anhui rice fields had varying degrees of resistance to penoxsulam. Among the tested samples，20 resistant populations accounted for 50% of the total number，including 13 medium and high-resistant populations accounted for 31. 5% of the total number. The resistance levels of E. crus-galli cwere much higher in the plain area along the Yangtze River and the Jianghuai hilly region，followed by a mountainous area of southern Anhui. In contrast，the resistance levels in plain regions in Huaibei Plain and Dabie Mountains were much lower. The resistant population R was resistant to metazosulfuron， bispyribac-sodium，quinclorac，cyhalofop-butyl，tripyrasulfone，sensitivity to pyraclonil， oxadiazon，thiobencarb，anilofos，and metamifop was lower. At the same time，it was sensitive to pretilachlor，butachlor，pendimethalin，butralin，and propanil.

Key words: Echinochloa crus-galli, penoxsulam, resistance level, resistance distribution, sensitivity
