笔者不久前曾被中华人民共和国农业部派遣到美国考察苏芸金杆菌的生产和应用情况,后来又与来华的美国微生物防治考察团进行过技术交流。现将有关资料摘要介绍,供参考。近年来,美国利用昆虫病原微生物防治农林害虫的工作有较大发展。如1975年,以棉铃虫核多角体为活性成分的病毒制剂“elcar”投产,1980年以多毛菌为活性成分的真菌制剂“Mycar”投产。尽管品种增多了,但从生产规
Not long ago, I was dispatched to the United States by the Ministry of Agriculture of the People’s Republic of China to study the production and application of Bacillus thuringiensis, and later exchanged technical exchanges with the United States delegation to China in the field of microbial control. Now the summary of the information introduced for reference. In recent years, the United States has made great progress in using insect pathogenic microorganisms to control agricultural and forestry pests. For example, in 1975, “elcar”, a virus preparation based on the nucleocapsid of Helicoverpa armigera (HpNp), was put into operation. In 1980, Mycar, a fungus preparation containing the active substance of Humicola, was put into operation. Despite the increased variety, but from the rules of production
