随着绿色农业的迅速发展,能够防治农作物病虫害的各种低毒、无公害农药正成为中国农药行业主攻的方向。在前不久举办的2005中国(南京)国际肥料农药展览会上,一批具有自主知识产权的高效无公害农药新产品集体亮相。运用纳米技术促使植物细胞破壁,使有效的脂溶性和水溶性的杀虫物质有效释放并直接作用于害虫,可极大地提高农药药效。四川省农科院和广汉恒宇新材料有限公司协同攻关,目前成功研制出环保、高效低毒的植物源纳米生物农药。这种通过对烟碱进行纳米化技术加工制备而成的纳米生物农药,对人畜完全无毒害副作用,而杀虫效果达到普通农药的3倍。
With the rapid development of green agriculture, various low-toxic and pollution-free pesticides that can prevent crop pests and diseases are becoming the main direction of China’s pesticide industry. In the recently held 2005 China (Nanjing) International Fertilizer and Pesticide Exhibition, a group of new products with independent intellectual property rights of highly efficient pollution-free pesticides appeared. The use of nanotechnology to promote plant cell wall, the effective fat-soluble and water-soluble pesticides effectively release and direct action on pests, can greatly improve the pesticide efficacy. Sichuan Academy of Agricultural Sciences and Guanghan Hengyu New Materials Co., Ltd. collaborative research, the successful development of environmental protection, high efficiency and low toxicity of plant-derived nano-biological pesticides. The nano-biological pesticide prepared through the process of nanocrystallization of nicotine has completely no poisonous side effects on humans and animals, and the insecticidal effect is three times of that of common pesticides.
