Problems solved by technology

If thiamethoxam, dinotefuran, tebuconazole or hymexazol are used alone for seed treatment, the purpose of the seed treatment agent is relatively single, either killing insects or fungi, and the combined effect is poor, and it is easy to produce antibiotics. sex

Embodiment 1

[0094] Embodiment 1: preparation of suspension

[0095]40% active compound (20.0% thiazole zinc and 20.0% cyclostrobin composition), fatty alcohol polyoxyethylene ether 2.0%, alkyl naphthalene sulfonate 3.0%, sodium methylene dinaphthalene sulfonate 1.0%, Xanthan gum 0.05%, magnesium aluminum silicate 0.6%, sodium starch octenyl succinate 2.3%, glycerin 2.0%, phenyl salicylate 0.4%, silicone defoamer 0.1%, deionized water to make up to 100%, put it into a high-shear homogeneous emulsifier and shear at high speed for 20 minutes, then transfer it to a sand mill, and circulate sand mill for 1-3 times to obtain a suspension containing 40% active compound.

Embodiment 2

[0096] Embodiment 2: preparation of microcapsule suspension

[0097] Zinc thiazole 10.0%, cyprostrobin 15.0%, alkyl naphthalene sulfonate 2.0%, acyl glutamate 1.0%, silicone defoamer 0.1%, polyphenyl polymethylene polyisocyanate PAPI 3% Mix well with 2% diphenylmethane diisocyanate MDI, 10% aqueous solution of gum arabic (5%), and 40.46% deionized water, and then put it into a sand mill for sanding until D 90 The particle size is 3-5 microns. Start stirring (maintain 700 rpm), then raise the temperature of the sand-milled suspension to 60°C, and slowly add 0.04% triethanolamine at the same time to maintain a stable solidification temperature of the capsule wall material for 8 hours, then add fatty alcohol polyoxyethylene ether Sulfate 1.0%, sodium methylnaphthalenesulfonate formaldehyde condensate 1.0%, urea 2.0%, glycerol 2.0%, aluminum magnesium silicate (2%) aqueous solution 10%, appropriate amount of dilute hydrochloric acid aqueous solution to adjust the pH value to abou...

Embodiment 3

[0098] Embodiment 3: preparation of water dispersible granules

[0099] 60% active compound (20.0% thiazole zinc, 25.0% cyprostrobin and 15.0% thiamethoxam combination), lignosulfonate 3.0%, naphthalene sulfonate 3.0%, ammonium sulfate 15.0%, xanthan gum 1.0 %, 1.0% talcum powder, and 17.0% kaolin are fully mixed, and then crushed by airflow and granulated to obtain water-dispersible granules. The water dispersible granules contain 60% active compound, and the particle size of the product is 80-120 mesh.

Abstract

The invention belongs to the field of pesticides, and relates to an agricultural composition, in particular to an agricultural composition containing zinc thiazole and phenamacril, and a preparation and application thereof. The agricultural composition containing zinc thiazole and phenamacril contains an effective component A and an effective component B; the effective component A is zinc thiazole; the effective component B is phenamacril; and the agricultural composition further contains an effective component C selected from any one of thiamethoxam, dinotefuran, tebuconazole and hymexazol. A dosage form prepared from the agricultural composition is capable of effectively delaying resistance and can be used for preventing and treating pathogenic bacteria, oomycete and fungal diseases of crops; the agricultural composition containing thiamethoxam or dinotefuran can also be used for preventing and treating diseases and insect pests simultaneously; and the agricultural composition disclosed by the invention is mainly used for processing crop seeds and soil, and has the advantages of being high in efficiency, low in toxicity and residual, good in environmental compatibility and low in cost.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to an agricultural composition, in particular to an agricultural composition containing thiazole zinc and cyclostrobin, as well as its preparation and application. Background technique [0002] Zinc Thiazole (Zinc Thiazole, Zn Thiodiazole) is a thiadiazole organic zinc fungicide, the chemical name is: bis(2-amino-1,3,4-thiadiazole-5-thiol) zinc, and its chemical structure is as follows: [0003] [0004] (CAS No: 3234-62-6) [0005] Zinc thiazole is a new pesticide (ZL00132119.6) independently developed and created by the applicant. It is a new generation of high-efficiency and low-toxic organic zinc agricultural fungicide for the prevention and treatment of bacterial diseases of crops. It has a good preventive effect on some fungi and is mainly used in rice. Prevention and control of bacterial diseases such as bacterial blight, bacterial streak, and citrus canker. [0006] Zinc thiazol...
