试验研究和生产实践证明,洗衣粉不仅对多种农林害虫直接具有杀灭作用,而且经济方便,对人、畜无害,不污染环境,是一项值得大力推广的植保新技术。 一、作用原理 一是洗衣粉中的烷基苯磺酸钠具有致毒作用,通过呼吸道进入虫体后可使害虫中毒死亡;二是洗衣粉溶液具有湿润、展布性,与虫体接触后会在其表面迅速形成一层不透气的薄膜而使害虫窒息死亡;三是洗衣粉溶液具有粘着性,成虫接触后被沾粘而不能起飞,时间一长即自然死亡。
Experimental studies and production practices have proved that washing powder not only has a direct killing effect on a variety of agricultural and forestry pests, but also is economically convenient, harmless to humans and animals, does not pollute the environment, and is a new plant protection technology worthy of promotion. First, the principle of action First, detergent in the sodium alkyl benzene sulfonate has toxic effects, through the respiratory tract into the parasites can cause pests poisoning; Second, the detergent solution with moist, spread, and the parasites contact Will quickly form a layer of impermeable film on the surface of the pest suffocation death; Third, the detergent solution with adhesive, adult contact is sticky and can not take off after a long time that natural death.
