三氟氯氰菊酯具有极强的胃毒和触杀作用,杀虫谱广,主要用于治疗棉花、蔬菜、烟草等农作物上的害虫,本品杀虫作用快,持效长,对益虫毒性也较低;但它的水溶性不好,在实际应用中药效不能充分发挥;而且造成了药物的浪费,也增大了对环境的污染。如果把它制成微胶囊就能够增加水溶性和改变表面张力,并且使药物达到缓释效果[1];使用安全,贮运方便,而且还保留了人们所熟悉的三氟氯氰菊酯乳油和可湿性粒剂所具有的杀虫谱广、对环境毒性低的优
Cyhalothrin has a strong stomach poisoning and contact toxicity, broad insecticidal spectrum, mainly for the treatment of pests on cotton, vegetables, tobacco and other crops, the insecticidal effect of this product fast, long-lasting, low toxicity to beneficial insects ; But its water-solubility is not good, its efficacy can not be fully exerted in practical application; moreover, it causes the waste of medicine and also increases the pollution to the environment. If it is made into microcapsules can increase the water solubility and change the surface tension, and make the drug to achieve sustained release [1]; safe, easy storage and transportation, but also retains the well-known cyhalothrin EC and wettability Granules have a broad spectrum insecticide, low toxicity to the environment
