Problems solved by technology

[0004] Apple spider mite: It mainly harms the leaves. Gray spots appear on the leaves at the beginning of the damage. In severe cases, the leaf cloth becomes grayish white, but the leaves do not fall, which mainly affects the photosynthesis of the crops. It not only causes the leaves to wither and yellow, but also causes the tree to wilt. cause serious impact

Embodiment 1

[0022] Weigh 800 parts of triazole tin original powder, 20 parts of wetting agent alkyl sulfate, 30 parts of dispersant fatty alcohol polyoxyethylene ether, 20 parts of disintegrant ammonium sulfate, 10 parts of adsorbent diatomaceous earth, stabilizer 20 parts of disodium hydrogen phosphate and 90 parts of light calcium carbonate as filler. After mixing them evenly, they are pulverized by jet mill to obtain master powder. Mix the master powder with 10 parts of binder polyvinyl alcohol, then granulate and dry. , Screening to obtain triazole tin water dispersible granules, in the implementation of the control effect of the apple red spider is 89.01 to 97.89%.

Embodiment 2

[0024] Weigh 750 parts of triazole tin powder, 26 parts of sodium alkyl sulfonate as wetting agent, 37 parts of alkylphenol polyoxyethylene ether as dispersant, 28 parts of anhydrous sodium sulfate as disintegrant, and 14 parts of white carbon black as adsorbent After mixing them uniformly, pulverize with a jet mill to obtain master powder, mix the master powder with 17 parts of binder gelatin uniformly, then granulate, dry and pass The triazole tin water dispersible granules are obtained by sieving. In the implementation, the control effect on the control of citrus red spider is 90.08 to 98.11%.

[0025] In order to enable those of ordinary skill in the art to better understand the present invention, the present invention provides a preparation method for triazole tin water dispersible granules, which has the following steps:

[0026] a) Select the raw materials according to the formula of triazole tin water dispersible granules, and mix them evenly;

[0027] b) The above mixture i...

Abstract

The present 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 granules and a preparation method thereof. [0002] Mainly used for the control of apple red spiders and citrus red spiders. Background technique [0003] At present, there are many acaricides used in agriculture. Triazotin is one of them. It belongs to organotin acaricides and is a broad-spectrum acaricide with strong contact effect. It can kill nymphs, adult mites and summer eggs, but is not effective for winter eggs. It has good stability to light and rain, and has a longer residual effect period. It is safe for crops at common concentrations. At present, the original triazole tin powder single agent on the market is generally made into low-content wettable powder for use and low-content emulsifiable concentrate. In addition, wettable powders and emulsifiable concentrates are seriously polluted during the preparation and use...
