【摘要】 应用有一定耐药性的蜡蚧轮枝菌菌株与多菌灵混配防治大棚冬春番茄烟粉虱,全程3个多月,施用6次,中期加用1次杀菌剂(甲霜灵+代森锰锌),能有效控制粉虱和协调病害防治,在前三次防治后粉虱成虫虫口控制在3～9.8头/株,幼虫虫口2～10头/株,病害病叶率2%～7%。
【Abstract】 The sound results have been gotten by using the fungicide tolerance strain of Verticillium lecanii to control the pest,Bemisia tabaci.During 3 months of the tomato growth,six applications of Verticillium lecanii and 1 application of fungicide(Metalaxyl+Mancozib) were been used.After the first 3 applications,the white-fly population was reduced to 3～9.8 adults and 2—10 nymphas per plant,and the disease leaf rate was under 2%～7%.
