Over the years the prevention and treatment of soybean aphids are based on chemical agents sprayed, due to the spraying area, resulting in a large number of natural enemies were killed, resulting in serious environmental pollution. To change this traditional method of application. Our school from 1981-1983, for three consecutive years in our province Kaiyuan, Haicheng County, 11 soybean production area of 2,400 acres of area, conducted a carbofuran Granula test soybean aphid test. The results showed that during the sowing period, fenvaleram could control the occurrence of soybean aphid for 50-80 days. During the cultivation period, fenvalerate affected the effect of rainfall, soil moisture and application method, medicine
