Abstract

The invention discloses an azocyclotin acaricide, belonging to acaricide technology of plant protecting field. The invention composition comprises fenbutatin oxide 10-800 parts, moistening agent 10-40 parts, dispersing agent 20-40 parts, disintegrating agent 10-50 parts, sorbent 10-60 parts, adhesive agent 10-30 parts, stabilizing agent 10-70 parts and filling material 50-500 parts. The above components are pro rata mixed and evenly stirred, then mesh powder obtained through disintegrating is evenly stirred with the adhesive agent, and azocyclotin moisture free-flow agent is processed through granulating, drying and sieving. The azocyclotin acaricide of the invention overcomes shortages of the conventional agent type of azocyclotin, lowers utilizing cost for farmers and environmental pollution. During utilizing process, the chemical compound fenbutatin oxide moisture free-flow agent of the invention has the advantages of high content, fast disintegration, great dispersibility, favorable storing and transporting, great stability, high activity, great efficiency and safety, which is mainly applicable for preventing and curing European red mites and citrus red mites.

Description

technical field [0001] The invention relates to an agricultural acaricide, the active ingredient is triazolium tin, the dosage form is water dispersible granule and the preparation method thereof. [0002] It is mainly used for the control of apple red spider and citrus red spider. Background technique [0003] At present, there are many agricultural acaricides, and triazolium tin is one of them, which belongs to the organotin class of acaricides and is a broad-spectrum acaricide with strong contact killing effect. It can kill nymphs, adult mites and summer eggs, but is invalid for winter eggs. It has good stability to light and rain, and has a long residual period. Safe for crops at commonly used concentrations. At present, the single agent of tin triazolium powder on the market is generally made into low-content wettable powder and low-content emulsifiable concentrate. Moreover, wettable powder single agent and emulsifiable concentrate are seriously polluted in the pro...
