中国是世界上最大的农业国之一,化学农药对防治农作物病虫害发挥了十分重要的作用,但其对环境、生态的负面影响也已引起广泛关注。中国政府鼓励发展生物农药,开发热点是微生物杀虫剂,包括B_1、病毒、真菌、线虫和微孢虫等。B_1已进人大规模工业化生产阶段,产品达到国际90年代同类产品水平,这对推动中国生物农药的发展起了重要的推动作用。 Bt:筛选新菌株是十分活跃的领域,我国着重从自然界——昆虫尸体和土壤中分离Bt菌株,湖北B_1研究开发中心(BtRDC)、华中农业大学、中国
China is one of the largest agricultural countries in the world. Chemical pesticides have played a very important role in controlling crop pests and diseases, but its negative impact on the environment and ecology has also attracted widespread attention. The Chinese government encourages the development of bio-pesticides and the development of hot spots is microbial pesticides, including B_1, viruses, fungi, nematodes and microspores. B_1 has entered the stage of large-scale industrial production. The products have reached the level of similar products in the international 1990s, which has played an important role in promoting the development of Chinese biological pesticides. Bt: Screening for new strains is a very active field. China focuses on the isolation of Bt strains from the natural world – insect carcasses and soils, Hubei B_1 Research and Development Center (BtRDC), Huazhong Agricultural University, China
