全国《以菌治虫》座谈会于10月28—31日在浙江省黄岩县召开。会上广泛交流了以菌治虫生物防治的经验,参观了黄岩县应用杀蚜素防治柑桔害虫的万亩样板,並有五位专家作了关于国内外以菌治虫情况的专题报告。 近年来我国以菌治虫的生防工作有所发展。农田抗菌素面积比1978年6000万亩增加了两倍,病毒治虫也有了较大幅度上升,细菌杀虫剂仍维持在1500万亩,真菌农药则由2000万亩下降为1200万亩。可喜的是以菌治虫的品种不断增加,如金龟子乳状菌的研究已由室内进入田间,微孢
The symposium on “controlling bacteria by bacteria” was held in Huangyan County, Zhejiang Province on October 28-31. Extensive exchange of experience in the biological control of bacteria and pests visited Huangyan County, the application of aphids to control citrus pests million mu model, and five experts made a special report on the status of bacteria in the world. In recent years, our country’s biocontrol work has been developed. The area of farmland antibiotics has more than doubled from 60 million mu in 1978, and the virus pest control has also risen sharply. The amount of bacterial pesticides still remains at 15 million mu and that of fungal pesticides dropped from 20 million mu to 12 million mu. The good news is that the species of pest control bacteria continue to increase, such as beetle mildew research has entered the field from the room, microsporum
