Abstract

The invention discloses a compound pesticide preparation containing metalaxyl and azoxystrobin. The preparation comprises metalaxyl and azoxystrobin at weight ratio of (1-9):1; and the metalaxyl and azoxystrobin respectively account for 10.0-63.0% and 2.0-35.0% of the total weight of the preparation. The formulation of the preparation is granules, tablets or suspending agents, wherein the granules or tablets are easy to measure in the use so as to avoid the unsatisfactory prevention effect due to too low dosage, or the waste of pesticide preparation and phytotoxicity to the crops due to too high dosage caused by inaccurate measurement, and the dosage of the pesticide can be reduced to some extent, thereby reducing the pollution of the pesticide to the environment and saving the prevention and control cost of fertilization and pesticide application; and the suspending agent provided by the invention is easy to mix with the water, and is convenient for use. In the compound pesticide preparation, water is used as the solvent to avoid the environmental pollution caused by the missible oil due to a large quantity of organic solvent and the environmental pollution caused by the shifting of the wettable powder in the process of preventing and controlling the diseases and insect pests; and therefore, the pesticide preparation has the advantages of low environmental influence, light phytotoxicity and the like, and is safe for production, storage and transportation and use.

Description
