微生物农药无残毒,无污染,有利于生态环境保护。我国自六十年代以来,通过引种和研制,已筛选、培养了许多菌种,如井岗霉素、春雷霉素、杀螟杆菌、苏云金菌、白僵菌和赤霉素(九二○)等已开始普遍应用,在某些病虫害的防治上起了很大作用。但发展还满足不了生产的需要,一是微生物农药品种少,而且有的因推广工作未做好,已停产。二是产量少,如我省水稻播种面积约6000万亩,防治纹枯病年需井岗霉素应在7000吨以上,而本省前几年最高产量不过700多吨,远远不能
Microbial pesticides without residue, no pollution, is conducive to ecological and environmental protection. Since the 1960s, many kinds of bacteria have been screened and cultivated in our country, such as Jinggangmycin, kasugamycin, Chromobacterium, Thielavia, Beauveria, and gibberellin (Jiuzuo) through introduction and development. Has begun to be widely used, in the prevention and treatment of certain pests and diseases played a significant role. However, the development still can not meet the needs of production. First, there are few varieties of microbial pesticides, and some have not been well-established for their promotion work. Second, less output, such as rice planting area of about 6,000 acres in our country, the prevention and control of sheath blight need Jinggangmycin should be more than 7,000 tons, while the province a few years ago the highest output but more than 700 tons, far from
