摘  要:
开展孢子萌发试验和室内盆栽试验测定26种杀菌剂对橡胶树白粉病菌的毒力。结果表明:在抑制病原菌孢子萌发的能力方面,吡唑醚菌酯、唑胺菌酯、氟菌螨酯、醚菌酯、烯肟菌胺、唑菌酯、氟菌唑、嘧菌酯、氟环唑、四氟醚唑、氟硅唑、乙嘧酚强于三唑酮,苯醚甲环唑、福美双与三唑酮相当;在抑制菌丝生长的能力方面,氟菌唑、唑菌酯、氟菌螨酯强于三唑酮,氟环唑、唑胺菌酯、氟硅唑、吡唑醚菌酯接近三唑酮,四氟醚唑稍弱于三唑酮。氟菌唑、唑菌酯、氟菌螨酯、氟环唑、唑胺菌酯、氟硅唑、吡唑醚菌酯、四氟醚唑8种杀菌剂可作为防治橡胶树白粉病的备选药剂。

摘  要:
Toxicity of 26 fungicides to Oidium heveae was determined in vitro and in vivo.Results showed that pyraclostrobin,SYP-4155,SYP-3759,kresoxim-methyl,SYP-1620,SYP-3343,triflumizole,azoxystr-obin,epoxiconazole,tetraconazole,flusilazole and ethirimol inhibited spore germination more strongly than triadimefon.Given the ability to suppress hyphal growth,triflumizole,SYP-3343 and SYP-3759 were better than triadimefon,and epoxiconazole,SYP-4155,flusilazole and pyraclostrobin were similar to triadimefon,while tetraconazole was slightly worse than triadimefon.Results led to a conclusion that triflumizole,SYP-3343,SYP-3759,epoxiconazole,SYP-4155, flusilazole,pyraclostrobin and tetraconazole are hopeful candidate fungicides for controlling rubber powdery mildew.
