Problems solved by technology

[0003] Apple spider mite: mainly harms the leaves. Gray spots appear on the leaves at the initial stage of damage. In severe cases, the leaf cloth becomes pale gray and white, but leaves do not fall. This mainly affects the photosynthesis of crops, not only causing leaves to turn yellow, but also causing tree wilting, which affects the entire physiological period. cause serious impact

Abstract

The invention discloses a chemical compound fenbutatin oxide moisture free-flow agent, belonging to acaricide technology in farm crop protecting field. The invention composition comprises fenbutatin oxide 10-800 parts, moistening agent 10-40 parts, dispersing agent 20-50 parts, disintegrating agent 10-50 parts, sorbent 10-30 parts, adhesive agent 10-30 parts, stabilizing agent 20-80 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 fenbutatin oxide moisture free-flow agent is processed through granulating, drying and sieving. The chemical compound fenbutatin oxide moisture free-flow agent of the invention overcomes shortages of the conventional agent type of fenbutatin oxide, 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 citrus red mites, European red mites, and citrus blister mites.

Description

technical field [0001] The invention relates to an agricultural acaricide, the active ingredient is phenbutyltin, the dosage form is water-dispersible granule and the preparation method thereof. It is mainly used for the control of citrus spider mites, apple spider mites, and citrus rust ticks. Background technique [0002] At present, there are many acaricides for agricultural use, among which fenbutatin belongs to the organic tin acaricide, which has strong contact killing effect on harmful mites, and strong lethality on nymphs, larvae and adult mites. Long-lasting acaricide, it begins to take effect 3 days after application, reaches the peak of acaricide in 14 days, and lasts for more than 2 months, even up to 100 days. It is a temperature-sensitive acaricide, and the higher the temperature, the more effective it is. The better it is, it can control resistant pest mites such as apple spider mite, citrus spider mite, and citrus rust tick. The existing phenbutyltin is mai...
