Description
Technical Field
The invention belongs to the technical field of pesticide compositions, and particularly relates to a pesticide composition containing fipronil and boscalid and a preparation method thereof.
Background
Rape, also called as cabbage, is mainly distributed in Anhui, Henan and Sichuan provinces. The rape is rich in nutrition, and the content of vitamin C in the rape is very high. Rape is typically grown in locations where the climate is relatively humid, such as the south of china. The main diseases harmful to the rape comprise sclerotinia rot, downy mildew, white rust and virus diseases of the rape; the main insect pests include aphids, cabbage caterpillars, simian leaf beetles, flea beetles and the like. Wherein, the sclerotinia rot and the aphid are the most serious, and if the control is not effective, the yield loss of the rape can reach 20 to 30 percent.
Meanwhile, with the national attention on environmental protection and the pursuit of the public on healthy and safe crops, the national pesticide yield is continuously reduced in nearly three years, and the pesticide application reduction and efficiency improvement and the low pesticide residue are paid more and more attention.
