在研究、开发和使用新型植物性杀虫剂的过程中,以菜青虫为主,对苦楝、川楝树皮中的呋喃三萜类物质——川楝素,从药效、致毒机理、使用技术以及剂型加工工艺等方面做了10多年的研究。这种植物性杀虫物质可破坏菜青虫的中肠组织,并引起一系列生理病变。用楝树皮提取物为主要成份加工配制成0.5％楝素杀虫乳油,取名“蔬果净”,已正式投入生产。该剂安全、高效,使用后无毒害残留,尤适于经济作物上防治有害昆虫,是配合“无污染”蔬菜、果品、茶叶、烟草、中草药等作物生产的良好药剂。
In the process of researching, developing and using new plant insecticides, the main component of Pieris rapae was tributyltin fumarate, Use of technology and dosage forms of processing technology has done more than 10 years of research. This botanical insecticide destroys the midgut tissue of Pieris rapae and causes a range of physiological disorders. With neem bark extract as the main ingredient processed into 0.5% of the azadirachtin insecticidal EC, named “net” fruits and vegetables, has formally put into production. It is safe, efficient and nontoxic residue after use. It is especially suitable for controlling harmful insects on cash crops. It is a good medicament for the production of “pollution-free” vegetables, fruit, tea, tobacco, Chinese herbal medicine and other crops.
