Abstract

The present invention relates to a hymexazol soluble granule and a preparation method thereof. The hymexazol soluble granule includes the components by weight: 10-80% of hymexazol, 1-4% of a wetting agent, 1-4% of a dispersing agent, 0.3-5% of a defoaming agent, 0.5-4% of binder, 1-2% of a stabilizer and the balance a carrier. The invention also discloses a preparation method of the hymexazol soluble granule. The hymexazol soluble granule does not contain toxic and flammable aromatic hydrocarbon solvents, thereby preventing flammable and explosive phenomena in production and storage processes. The hymexazol soluble granule has no unpleasant odor and noxious gas, has small irritation to eyes, reduces pollution to environment, and greatly improves security for production, storage and users.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a hymexazol soluble granule and a preparation method thereof. Background technique [0002] Hymexazol is a systemic fungicide and also a soil disinfectant, which has a good preventive effect on damping-off caused by pythium and fusarium. The drug combines with iron and aluminum ions in the soil to inhibit the germination of spores. Hymexazol can be absorbed by the roots of plants and move in the root system, and metabolize in the plants to produce two kinds of glycosides, which can improve the physiological activity of crops, thereby promoting plant growth, root division, root hair increase and root growth. Increased activity. [0003] The use of traditional pesticides, mainly emulsifiable concentrates and powders, played an irreplaceable role in preventing pests and diseases, capturing agricultural harvests, and ensuring people's lives when the productivity level was not...
