Embodiment 1

[0024] Take by weighing 780 parts of Methiocarb original powder, 30 parts of wetting agent alkamide taurate, 20 parts of dispersant alkylphenol polyoxyethylene ether, 20 parts of disintegrating agent bentonite, 20 parts of adsorbent lignin No. 55 10 parts, 10 parts of stabilizing agent borax, 100 parts of filler light calcium carbonate, after it is mixed uniformly, pulverizes and obtains mother powder through jet mill, mother powder is mixed with 20 parts of binding agent polyethylene glycols, then, then make granules, dried, and sieved to obtain amecarb water-dispersible granules, which have a control effect of 89.01% to 92.89% for controlling rice planthoppers during implementation.

Embodiment 2

[0026] Weigh 750 parts of Methiocarb original powder, 26 parts of wetting agent alkyl succinic acid sulfonate, 37 parts of dispersant fatty alcohol polyoxyethylene ether, 28 parts of disintegrating agent polyethyl acrylate, adsorbent attapulgite 14 parts of soil, 18 parts of stabilizer oxalic acid, 112 parts of filler kaolin, mix them evenly, and pulverize them through a jet mill to obtain mother powder, mix the mother powder with 15 parts of binder polyvinylpyrrolidone, then granulate and dry , and sieved to obtain the Memecarb water-dispersible granule, which has a control effect of 89.08% to 93.11% for controlling rice leafhoppers during implementation.

Embodiment 3

[0028] Take by weighing 770 parts of Methiocarb original powder, 30 parts of wetting agent fatty alcohol ethylene oxide adduct sulfonate, 35 parts of dispersant fatty alcohol polyoxyethylene ether, 24 parts of disintegrating agent anhydrous sodium sulfate, 12 parts of diatomite as an adsorbent, 15 parts of adipic acid as a stabilizer, and 100 parts of anhydrous sodium sulfate as a filler. After mixing them evenly, they are pulverized by a jet mill to obtain mother powder, and the mother powder is mixed with 14 parts of binder polyethylene glycol. Alcohol is mixed evenly, then granulated, dried, and sieved to obtain the water-dispersible granules of methiocarb, which has a control effect of 90.23% to 93.99% for the prevention and treatment of tea leafhoppers in practice.

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...
