Embodiment 1

[0022] Weigh 710 parts of tricyclazole raw powder, 30 parts of wetting agent alkamide taurate, 50 parts of dispersant alkylphenol polyoxyethylene ether, 50 parts of disintegrating agent bentonite, 30 parts of adsorbent lignin No. 55 30 parts, 30 parts of stabilizer borax, 80 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 tricyclazole water-dispersible granules, which have a control effect of 88.01% to 90.89% for controlling rice blast in practice.

Embodiment 2

[0024] Weigh 730 parts of tricyclazole raw powder, 36 parts of wetting agent alkyl succinic acid sulfonate, 47 parts of dispersant fatty alcohol polyoxyethylene ether, 40 parts of disintegrating agent polyethyl acrylate, adsorbent attapulgite 14 parts of soil, 18 parts of stabilizer oxalic acid, 100 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 tricyclazole water-dispersible granule, which has a control effect of 89.08-93.11% for controlling rice blast in practice.

Embodiment 3

[0026] Weigh 770 parts of tricyclazole former 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. Mix with alcohol evenly, then granulate, dry, and sieve to obtain tricyclazole water-dispersible granule, which has a control effect of 90.23-93.99% for controlling rice blast in practice.

Abstract

The invention discloses tricyclazole bactericidal agent belonging to the technology of bactericidal agent in the field of plant protection. The invention comprises tricyclazole 10-800 parts, humectant 10-50 parts, dispersing agent 10-50 parts, disintegrant 10-80 parts, adsorbent 10-50 parts, adhesion agent 10-30 parts, stabilizing agent 10-60 parts and filler 50-500 parts. The above components are mixed according to a certain proportion, homogeneously agitated, disintegrated for mesh powder, mesh powder and adhesion agent are homogeneously mixed, and then the tricyclazole water dispersible granule is achieved after granulation, drying and riddling. The invention overcomes the defects of prior tricyclazole agent, decreases the application costs for farmers and environment pollution. Besides, the invention has the advantages of high content, rapid disintegration, good dispersibility, convenient storage, stability, high activity degree, good effect and safety. The invention is mainly used for prevention and cure of rice blast.

Description

technical field [0001] The invention relates to an agricultural acaricide, the active ingredient is tricyclazole, the dosage form is water-dispersible granule and the preparation method thereof. It is mainly used for the control of rice blast. Background technique [0002] At present, there are many agricultural fungicides, and tricyclazole is one of them. Its mechanism of action is mainly to inhibit the germination of spores and the formation of attached spores, thereby effectively preventing the invasion of pathogens and reducing the production of spores of Magnaporthe grisea. It is a strong systemic triazole fungicide, which can be quickly absorbed by rice roots, stems, and leaves, and transported to various parts of the plant. It has high activity, long-lasting effect, stable drug effect, and strong rain erosion resistance. , There is no need to respray if it rains one hour after spraying. [0003] Rice blast: also known as rice fever, fire blast, and knocking head bla...
