【摘要】 <正>本研究测定12种杀虫剂和5种除草剂对蜡蚧轮枝菌孢子萌发的影响。结果表明,杀虫剂绿宝及菜蛾敌两品种与蜡蚧轮枝菌完全兼容,在50倍下未检出有杀伤作用。天霸对蜡蚧轮枝菌孢子萌发无明显影响,,安全值(LC₅₀与田间使用浓度之比)较高（11.49）,可与蜡蚧轮枝菌兼容使用。先力、一遍净对蜡蚧轮枝菌孢子萌发有一定的影响(LC₅₀分别为2.486×10^-3和1.163×10^-4),安全值为6.9-7.5,可在一定程度上兼容使用。万灵、氯氰菊酯、敌杀死、功夫乳油、虫死净、速蚧克、来福灵等更多还原

【Abstract】 The effect of 12 pesticides and 5 herbicides on the germination of conidia of Verticillium lecanii were investigated in this paper.The results showed:pesticide Lubao （Avermectin） and Caiedi（Bt+Avermectin） can be compatible with Verticillium lacanii completely.Tianba（Bt WP） has slight suppression effect on the Verticillium lecanii(LC₅₀ = 7.18×10^-3,Safety value= 11.49) and can be used together.Xianli（Bt Water dispersal formulation） and Imidacloprid（WP） have some suppressive effect on Verticillium lecanii(LC₅₀:2.486×10^-3 and 1.163×10^-4) and can be used together in some extension （S = 6.9- 7.5）.Wanling,Cypermethrin,Deltamethrin,Cyhalothrin,Chongsijing, Shujieke,Esfenvalerate have high suppression effect(LC₅₀:5.93×10^-4、3.17×10^-5、5.93×10^-6、2.22×10^-6、9.52×10^-5、5.15×10^-5、1.77×10^-5) on Verticillium lecanii and can not be used together（S=1-2.6）.Among the herbicides,only Nicosulfuron has no any suppression to Verticillium lecanii.Then haloxyfop-R-methyl,Nitrofen, Bensulfuron methyl and Quizalofop-ethyl have suppression to Vertillium lecanii (LC₅₀:1.740×10^-4,1.881×10^-4、5.943×10^-5,2.908×10^-5) and have no compatiblity with Verticillium lecanii（S= 1.61-0.29）.But the toxicity can be reduced in the field and the germination rate can reach to 87%-93%after exposed 2 to 4 days at the application concentration in the field although those chemicals are high toxic to Verticillium lecanii.The interval duration such as 2-4 days should be take consideration in the field application.更多还原
