摘　　要：本文检测了18种常用低毒化学农药对生防真菌绿僵菌Metarhizium anisopliae孢子萌发、菌丝生长及产孢的影响,分析它们与绿僵菌的相容性。总体看,杀虫剂、植物生长调节剂和除草剂与绿僵菌的相容性好于杀菌剂。其中,氰戊菊酯与绿僵菌相容性最好,即使在10倍的推荐浓度下,对孢子萌发无影响,对菌丝生长速度和产孢量的抑制率只有25.13%和38.63%。高效氯氟氰菊酯和乐果与绿僵菌也有较好的相容性,在推荐的田间使用浓度下,孢子萌发抑制率为30%左右,对菌丝生长和产孢量基本没有抑制。溴氰菊酯、啶虫脒、吡虫啉、甲霜灵、氟乐灵、阿维菌素、敌百虫、毒死蜱和波尔多液与绿僵菌有一定的相容性。矮壮素、哒螨灵、多菌灵、甲基硫菌灵、代森锰锌和三唑酮与绿僵菌相容性很差。Impacts of eighteen low-toxicity commercial chemical pesticides on conidial germination,mycelial growth and sporulation of Metarhizium anisopliae,an entomopathogenic fungus as biocontrol agent,were tested to evaluate compatibility between the fungus and the pesticides.Results showed that the tested insecticides,plant growth regulators and herbicides were more compatible with the fungus than the tested germicides.Among them,deltamethrin showed the highest compatibility with the fungus.Even at ten times of recommended concentration,it had no inhibition on conidial germination and only inhibited mycelial growth by 25.13% and sporulation by 38.63%.Lambda-cyhalothrin and dimethoate demonstrated moderate compatibility with the fungus.Their inhibition rates on conidial germination were about 30%,but no inhibition on mycelial growth at the recommended concentration.Deltamethrin,acetamiprid,imidacloprid,metalaxyl,trifluralin,abamectin,trichlorphon,chlorpyrifos and bordeaux mixture showed lower compatibility with the fungus,while chlormequa,pyridaben,carbendazim,thiophanate-methyl,mancozeb and triadimefon were hardly compatible with the fungus.
