Abstract

The invention discloses compound imines azoles water dispersible granule which belongs to the bactericidal agent technology in the field of agronomic crop protection. The invention comprises imines azoles 80-800 parts, humectant 20-40 parts, dispersing agent 20-40 parts, disintegrant 20-80 parts, adsorbent 10-30 parts, adhesion agent 10-50 parts, stabilizing agent 10-40 parts and filler 50-500 parts. The above components are mixed according to a certain proportion, homogeneously agitated, disintegrated for mesh powder, mesh powder and adhesion agent are homogeneously mixed, and then the imines azoles water dispersible granule is achieved after granulation, drying and riddling. The invention overcomes the defects of imines azoles wettable powder and decreases application costs for farmers and environment pollution. Besides, the invention has the advantages of high content, rapid disintegration, good dispersibility, convenient storage, stability, high activity degree, good effect and safety. The invention is mainly used for the prevention and cure of citrus scab, anthracnose of grape and venturia pirina.

Description

technical field [0001] The invention relates to an agricultural fungicide, the active ingredient is imidazole, the dosage form is water-dispersible granule and the preparation method thereof. It is mainly used for the prevention and treatment of citrus scab, grape black pox and pear tree scab. Background technique [0002] At present, there are many agricultural fungicides, and imidazole is one of them. It belongs to the broad-spectrum foliar systemic fungicide of azoles. biosynthesis, thereby destroying the formation of cell membranes, leading to the death of germs, can quickly penetrate into plants after spraying, and is resistant to rain erosion. It is mainly used to prevent and control fungal diseases of crops. It has good safety, wide bactericidal spectrum and outstanding effect. It is one of the products with better effect, higher activity and less dosage in the control of fungal diseases. However, the imidazole raw powder currently on the market is generally made in...
