试验研究和应用实践表明,洗衣粉对多种农林害虫具有杀灭作用,而且经济简便,对人、畜无毒,不伤天敌且对作物比较安全,不污染环境,是一项值得推而广之的植保技术。 一、作用原理 1、洗衣粉的主要成分是十二烷基磺酸钠,通过呼吸道进入虫体后可使害虫中毒死亡。不同工厂生产的产品,有效成分含量稍有差异,一般在20％～30％之间,此外,还有其他6～7种化学成分,这些成分各有其作用,如三聚磷酸五钠,主要降低水的表面张力及兼作填料。
Experimental research and practical application show that washing powder has a killing effect on many kinds of agricultural and forestry pests and is economical and convenient. It is nontoxic to human beings and animals, does not harm natural enemies, and is relatively safe to crops and does not pollute the environment. The plant protection technology. First, the principle of action 1, the main component of detergent is sodium dodecyl sulfate, after entering the parasites through the respiratory tract can make pests poisoning death. Different factories produce products, the active ingredient content slightly different, generally between 20% to 30%, in addition, there are other 6 to 7 kinds of chemical composition, these ingredients have their own role, such as pentasodium tripolyphosphate, the main Reduce the surface tension of water and doubles as filler.
