洗衣粉中含有烷基苯磺酸钠,可通过吸道进入虫体引起中毒死亡;洗衣粉水溶液喷到害虫体上后可浸润害虫体壁,使害虫脱去体壁、蜡质层,并可形成一层薄膜封闭气孔,使害虫窒息死亡;洗衣粉水溶液还可以粘着成虫翅膀,使其失去飞翔能力,利于人工捕杀及其它药剂防治,且洗衣粉对人畜和作物安全、不污染环境、不伤天敌。 据试验,在各种害虫的防治关键期,连续用药、效果甚好。试验结果如下: 防治梨木虱,于成虫出蛰盛期间隔7—10天,连续喷施3—5次,1000倍洗衣粉液,害虫死亡率达89.5％以上。 防治介壳虫类,于第一代卵孵化盛期和第二代卵孵化盛期,间隔3—5天,连续喷施3次500—800倍洗衣粉液,害虫死亡率为95—99.5％。 防治卷叶蛾类,于幼虫出蛰盛期,间隔3—5
The detergent contains sodium alkyl benzene sulfonate, which can cause poisoning and death by entering the parasites through the airway. After the aqueous detergent solution is sprayed onto the insect body, the insect body wall can be infiltrated so that the insect peels off the body wall and the waxy layer, and the Forming a layer of film closed stomata, the pest suffocation death; detergent aqueous solution can also stick adult wings, so that it lost the ability to fly, which is conducive to the manual killing and other agents prevention and control, and washing powder on human and animal and crop safety, does not pollute the environment, does not hurt Natural enemies. According to the test, in a critical period of prevention and treatment of various pests, continuous medication, the effect is very good. The test results are as follows: Prevention and control pear psylla, in adult stagnant Sheng period interval 7-10 days, spraying 3-5 times in a row, 1000 times detergent liquid, pest mortality rate of 89.5%. Control scale insects, in the first generation of egg hatching peak and the second generation of egg hatching peak interval 3-5 days, three consecutive spraying 500-800 times washing powder, pest mortality was 95-99.5%. Control of leaf roller moths, in the larvae out of staggered period, interval 3-5
