螨虫素是从土壤微生物中提取的大环内酯类抗生素,系纯生物药剂,九十年代初由江苏省农科院植保所科技人员研制,并率先开发、应用于防治农作物害虫。1993年6月通过产品技术鉴定,受到国内生防、植保及农药界专家的极大关注,普遍认为具有广阔的发展前景。 该药剂的显著特点是:①对害虫具有胃毒和触杀双重作用,可广泛用于防治棉花、蔬菜、果树、园林、花卉、中草药材及食用菌的害螨和害虫,尤对螨类有特效;②防治作物螨虫用量低,田间施用有效浓度0.5—1.5ppm即可控制其危害。对具严重抗药性的蔬菜害虫——小菜蛾防效明显,有效浓度1ppm时防效可达95％;③无污染,无残留。 目前,螨虫素已制成可湿性粉剂,生产工艺和产品质量均达到国家标准,在我国沿海部分省、市试用推广后,经济效益显著,可望出口创汇。
Mitechin is a macrolide antibiotic extracted from soil microorganisms. It was a pure biological medicine. In the early 1990s, it was developed by scientific and technical personnel of Plant Protection Institute of Jiangsu Academy of Agricultural Sciences and took the lead in developing and applying to control pests of crops. June 1993 through product technology appraisal, by the domestic biological control, plant protection and pesticide industry experts great concern, generally considered to have broad prospects for development. The remarkable features of the medicament are as follows: (1) It has the double functions of gastric poisoning and contact with insects, and can be widely used for controlling pests and pests of cotton, vegetables, fruit trees, gardens, flowers, Chinese herbal medicines and edible fungi, especially for mites ; ② control crops mites low dosage, the field of effective concentration of 0.5-1.5ppm can control the harm. On the serious resistance of vegetable pests - diamondback moth significant effect, the effective concentration of 1ppm when the control effect of up to 95%; ③ no pollution, no residue. At present, mite has been made WP, production technology and product quality have reached the national standard, some provinces and cities in China’s coastal provinces to promote the trial, the significant economic benefits, is expected to export earnings.
