摘要: 在四川稻区多年的监测结果表明:水稻二化螟对杀虫双、杀虫单已达中等抗性水平至高抗水平(41.97~371.9倍),对三唑磷的敏感性降低;稻飞虱对吡虫啉相对敏感,对噻嗪酮、敌敌畏的敏感度降低;稻瘟病对异稻瘟净产生了抗性,抗性菌株频率为20.51%~56.41%,对稻瘟灵的敏感性降低,抗性菌株频率为3.52%~9.52%,对三环唑的敏感性也有下降的表现,病斑出现率为0.4%。水稻几种重要病虫的抗性风险较大,其抗性治理势在必行。

Abstract: Results of resistance monitoring in Sichuan show that Chilo suppressalis walker is from middle to high resistance to Bisultap, Molosultap(times 41.97~371.9), and sensitivity to Triazophos depresses.Sogatella furcifera Horvath exerts relative sensitivity to Imidacloprid.And sensitivity of Sogatella furcifera Horvath to Buprofezin and Dichlorvos goes down.Pathogen of Rice blast(Pyricularia grisea) produce resistance to IBP and frequency of resistant strains is 20.51%~56.41%.The sensibility of the pathogen to Isoprothiolane reduces and the frequency of the resistant strains is 3.52%~9.52% and the sensibility to Tricyclazole shows the descendent trend, the frequency of spot appearance is 0.4%.The result of risking of resistance to pesticides is considerable and the resistance management is needed.
