一般的杀虫剂多含有机汞,虽然效力大,但对人体有害,喷施时易发生农药中毒,也有吃了喷过杀虫剂的蔬菜和水果的中毒事故发生。用肥皂粉代替杀虫剂,不但使用方便,而且不会中毒,同时成本可降低92%。把肥皂粉分别溶解在不同倍数的水中,喷洒在柑桔类果树上。当稀释液倍数为800倍时,红蜘蛛的死亡率为31%,蚜虫为9%,锈蜱为8%。减少稀释的倍数,虫体的死亡率便逐渐增加。到400倍时,死亡率分别达到95%、86%和83%。

Most of the general insecticide containing organic mercury, although effective, but harmful to humans, spraying prone to pesticide poisoning, but also eaten vegetables and fruits sprayed pesticide poisoning. Replacing insecticides with soap powder is not only easy to use but also less toxic, with a 92% cost reduction. The soap powder were dissolved in different times of water, sprayed on citrus fruit trees. When the dilution multiples of 800 times, the red spider mortality was 31%, aphids 9%, 8% of the rusty ticks. Reduce the dilution factor, the mortality of worms will gradually increase. At 400-fold mortality rates were 95%, 86% and 83% respectively.
