Abstract

The invention relates to a captan and imazalil compound composition, which is excellent in environmental compatibility, high in efficiency and low in toxicity and residue, and application thereof, in particular to application researches on prevention and treatment of apple ring spot, apple anthracnose, grape white rot and grape bitter rot. The weight ratio of the active ingredients, captan and imazalil, in the compound composition is (1: 2)-(16: 1). The captan and imazalil compound composition can be used for preventing and treating major diseases of fruit trees and particularly is excellent in preventing and treating apple ring spot, apple anthracnose, grape white rot and grape bitter rot.

Description

technical field [0001] The invention belongs to the technical field of fungicidal composition pesticides, and in particular relates to a compounded composition of captan and imazalil and its use as a fungicide. Background technique [0002] Apple ring spot, apple anthracnose, grape white rot, and grape anthracnose are one of the important diseases that seriously occur in the main fruit producing areas. In the foreseeable future, chemical fungicides will still be the main means of preventing and controlling fruit tree diseases, but the long-term unreasonable large amount of chemical pesticides has led to problems such as increased control costs, excessive fruit residues, environmental pollution, and the development of drug resistance. According to our hospital system The results of the resistance test showed that some of the fungicides resistant to common fungicides such as tebuconazole, carbendazim, and difenoconazole had developed low-level resistance to some fungicides.
