一种利用真菌杀灭害虫的生物农药近日在宁波开发成功。并已申请国家发明专利。与传统化学农药相比,该产品无任何化学毒性成分残留,喷药后即使当天采收农产品也检测不到农药残留。该产品一般持效期较长,但作用过程比化学杀虫剂稍慢。该成果突破了传统配方及制剂工艺两大难题。主要用于防治蔬菜、瓜果、茶叶等经济作物上的蚜虫、叶蝉等刺吸式口器害虫。保持期可达1年以上,一次性施用防效可达到70% A biological pesticide that uses fungi to kill pests has recently been successfully developed in Ningbo. And has applied for national invention patents. Compared with the traditional chemical pesticides, the product has no residue of any chemical toxic components, and pesticide residues can not be detected even after harvesting agricultural products on the same day. The product is generally longer duration, but the role of chemical pesticides slower than the process. The result has broken through the two major problems of traditional formula and preparation technology. Mainly for the control of vegetables, fruits, tea and other cash crops on the aphids, leafhoppers and other sucking mouthparts pests. Retention period of up to 1 year or more, one-time application of anti-efficacy can reach 70%
