摘　　要：通过药剂驯化和紫外诱导2种方法诱导J1、H1、DL1和DL2稻瘟病菌菌株对烯肟菌胺的抗性,并测定其对烯肟菌胺与嘧菌酯、稻瘟灵的交互抗药性。结果经药剂驯化的J1、H1、DL1和DL2菌株均对烯肟菌胺产生了中等抗药性;经紫外诱导DL1和DL2菌株对烯肟菌胺产生了中等抗性,J1和H1未产生抗性仍为敏感菌株;经测定稻瘟病菌对烯肟菌胺与嘧菌酯、稻瘟灵的交互抗药性表明烯肟菌胺与嘧菌酯具有交互抗药性,与稻瘟灵无交互抗药性。Through domestication of SYP-1620 and UV induce resistance of J1, H1, DL1 and DL2 ofMagnaporthe grisea to SYP-1620, and research the cross-resistance on SYP-1620 with azoxystrobin and isoprothiolane. As a result, J1, H1, DL, and DL2 were induced by SYP-1620 of fungicides which produced moderate resistance; DL, and DL2 were induced by UV which also produced moderate resistance, nevertheless, J, and H1 were still sensitive strains. The determination of cross-resistance on SYP-1620 with azoxystrobin and isoprothiolane showed that SYP-1620 had a cross-resistance with azoxystrobin but without cross-resistance with isoprothiolane.
