Abstract
The invention discloses a microbicide composition for preventing and controlling gray mold of fruits and vegetables, and belongs to the technical field of pesticides. The microbicide composition comprises the following active components in percentage by weight: 5%-60% of metconazole and 5%-60% of coumoxystrobin, wherein the weight ratio of the metconazole to the coumoxystrobin is (1 : 10) to (10 : 1). The invention further discloses application of the microbicide composition to prevention and control of the gray mold of the fruits and vegetables. According to the microbicide composition, the metconazole and the coumoxystrobin are compounded and various assistants are added, so that three dosage forms with excellent effects of preventing and controlling the gray mold of the fruits and vegetables are researched and developed, a remarkable synergistic effect on the gray mold is achieved, and the prevention and control effects can be remarkably improved; moreover, part of medium-high-toxicity microbicides can be replaced, the dosage is reduced, the environmental pollution is alleviated, and the agricultural product residues are reduced; due to the application of the microbicide composition to the prevention and control of the gray mold of the fruits and vegetables, the drug resistance of the gray mold on a single microbicide can be delayed, and the microbicide composition has the advantage of long lasting period.
