Tsumacide water dispersible granule and preparation method thereof

Abstract

The invention discloses an MTMC insecticide, which belongs to insecticide technology in plant protection field. The MTMC insecticide of the invention composition comprises MTMC 10-800 parts, humectant 10-50 parts, disperser 10-50 parts, disintegrant 10-80 parts, adsorbent 10-60 parts, adhesive agent 10-50 parts, stabiliser 10-60 parts and filling material 50-500 parts. The above components are pro rata mixed and evenly stirred, mesh powder obtained through disintegrating is evenly stirred with the adhesive agent, and MTMC moisture free-flow agent is processed through granulating, drying and sieving. The MTMC insecticide of the invention overcomes the shortages of MTMC wettable powder agent, changes the single actuality of the conventional agent type, lowers utilizing cost for farmers and reduces environmental pollution, with the advantages of high content, fast disintegration, great dispersibility, favorable storing and great stability. The MTMC insecticide has high activity, great efficiency and safety, which increases a great effect and non-pollution novel agent type for the conventional agent type. The MTMC insecticide of the invention is mainly applicable for preventing rice hoppers, rice leafhoppers, tree plant tea leafhoppers and tea plant spiny white flies.

Description

technical field [0001] The invention relates to an agricultural insecticide, the active ingredient is methiocarb, the dosage form is water-dispersible granule and the preparation method thereof. It is mainly used for the control of rice planthopper, rice leafhopper, tea tree green leafhopper, and tea tree blackthorn whitefly. Background technique [0002] Meprocarb has a strong contact killing effect on pests, strong knockdown power, and has a certain fumigation and infiltration effect. The drug effect is rapid. All have special effects. At present, the preparations of Methiocarb are mainly emulsifiable concentrates and wettable powders, and the content is mainly between 20-25%. However, the current preparations mainly have the following problems: (1) the content is low, and the dosage is large, which cannot reach Ideal effect, low efficiency, (2) low active ingredient usage, large filler usage, great environmental pollution, (3) inconvenient use, high cost of use. (4) lo...

AI Technical Summary

Problems solved by technology

At present, the preparations of Methiocarb are mainly emulsifiable concentrates and wettable powders, and the content is mainly between 20-25%. However, the current preparations mainly have the following problems: (1) the content is low, and the dosage is large, which cannot reach Ideal effect, low efficiency, (2) low amount of active ingredients used, large amount of filler used, great environmental pollution, (3) inconvenient to use, high cost of use

(4) Low safety factor, polluting crop leaves, inhibiting photosynthesis of crops, (5) complex packaging, inconvenient storage and transportation, (6) certain harm to human body when used

The photosynthetic efficiency of the damaged tea tree is reduced, the germination density is reduced, the germination is late, the buds and leaves are thin, and the leaves of the tea tree are severely fallen, which not only affects the yield and quality of tea, but also seriously affects the vigor of the tea tree.
