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

Abstract

The invention discloses a water-dispersible granule of a compound tetrafenazine, which belongs to the acaricide technology in the field of crop protection. The composition of the present invention comprises: 20-800 parts of tetrafenazine, 10-40 parts of wetting agent, 20-50 parts of dispersant, 10-50 parts of disintegrating agent, 10-30 parts of adsorbent, 10-30 parts of adhesive, Stabilizer 10-80 parts, filler 50-500 parts. The above ingredients are mixed in proportion, stirred evenly, crushed to obtain mesh powder, uniformly mixed with the mesh powder and adhesive, then granulated, dried and sieved to obtain tetrafenazine water-dispersible granule. The invention overcomes the disadvantages of the existing formulations of tetrafenazine, and reduces farmers' use costs and environmental pollution. Moreover, the present invention has the advantages of high content, fast disintegration, good dispersibility, good storage and stability, high activity, good efficacy and safety during use, and is mainly used for citrus spider mite, apple spider mite, and citrus red spider mite. Lice control.

Description

technical field [0001] The invention relates to an agricultural acaricide, the active ingredient is tetrafenazine, the dosage form is water-dispersible granule, and a preparation method thereof. [0002] It is mainly used for the control of citrus spider mites, apple spider mites, and citrus rust ticks. Background technique [0003] At present, there are many kinds of agricultural acaricides. Tetrafenazine is one of them. It belongs to organic nitrogen acaricides. It has a very strong lethality and can inhibit the egg laying rate of female adult mites and the hatching rate of eggs laid, so it is mainly used to kill the eggs of spider mites and rust ticks. Tetramethazine original powder single dose currently on the market is generally made into wettable powder and used as suspension concentrate. Moreover, wettable powder single agent and suspension concentrate are seriously polluted in the process of preparation and use, which is very harmful to people and the environment. ...
