武汉大学生命科学学院汪涛教授1986年参加了国家“七五”科技攻关,开始研究“农户自产高效苏云金杆菌—7216菌剂防治棉铃虫技术”,并于1988年获得成功。这种菌剂制法简单易行,普通农民用1个小时就可学会,原来要用两个小时制作,现在只要3～5分钟就行。具体做法是:在棉铃虫发生期,利用自然温度将麦麸、石灰和水作为培养基接种苏云金杆菌菌种,农民称为“麸子药”。棉铃虫食用菌剂后,由于药物的胃毒作用,造成中肠穿孔,上吐下泻,无法进食,自然死亡。去年,在国家经贸委、国家科委、国家教委等的支持下,汪涛教授率领科技人员在河北
Dr. Wang Tao, School of Life Sciences, Wuhan University participated in the national “Seventh Five-Year” scientific and technological research in 1986 and began to study the “Farming-Producing Highly Effective Bacillus thuringiensis-726 Agent for Prevention and Control of Cotton Bollworm”, and succeeded in 1988. The method is simple and easy to use. The common peasants can learn in an hour. It takes about two hours to produce, and now only takes 3 to 5 minutes. Specific approach is: in the occurrence of cotton bollworm, the use of natural temperature wheat bran, lime and water as a medium inoculated Bacillus thuringiensis strains, farmers called “bran medicine.” After the cotton bollworm edible fungus agent, due to the drug stomach poisoning, causing the midgut perforation, vomiting diarrhea, unable to eat, natural death. Last year, with the support of the State Economic and Trade Commission, the State Science and Technology Commission and the State Education Commission, Professor Wang Tao led scientific and technological personnel in Hebei
