一、甲维盐发展依赖阿维菌素的供应甲维盐(全称:甲氨基阿维菌素苯甲酸盐)是白色或淡黄色结晶粉末,溶于丙酮和甲醇、微溶于水、不溶于己烷,是从发酵产品阿维菌素B1开始合成的一种新型高效半合成抗生素杀虫剂,它具有超高效、低毒(制剂近无毒)、低残留、无公害等生物农药的特点。广泛用于蔬菜、果树、棉花等农作物上的多种害虫的防治。目前甲维盐已经成为我国替代、禁用或限用高毒农药的绿色生物杀虫剂。国内甲维盐有两条生产工艺路线,一是 First, the development of a-dimensional salt dependence on avermectin supply A-dimensional salt (full name: emamectin benzoate) is a white or light yellow crystalline powder, soluble in acetone and methanol, slightly soluble in water, insoluble In hexane, it is a new type of highly efficient and semi-synthetic antibiotic insecticide synthesized from the fermentation product abamectin B1. It has the characteristics of ultra-high efficiency, low toxicity (nearly non-toxic preparation), low residual and pollution-free biological pesticides Features. Widely used in vegetables, fruit trees, cotton and other crops on the prevention and treatment of a variety of pests. At present, A-dimensional salt has become our alternative, banned or limited use of highly toxic pesticides green bio-pesticides. A domestic salt has two production routes, one is
