Embodiment 1

[0019] Example 1: Cyazofamid 2%, cyclohexanone 10%, N-methylpyrrolidone 15%, the three are fully mixed and dissolved, then enter the blending kettle, and then add 10% castor oil polyoxyethylene ether, polyol Fatty acid ester and its ethylene oxide adduct 4%, benzenesulfonate 4%, pyrogallic acid 2%, after fully stirring and dissolving, make up to 100% with deionized water, continue stirring until transparent, and obtain 1 % Cyazofamido microemulsion.

Embodiment 2

[0020] Example 2: Cyazofamid 5%, ethyl acetate 15%, diethyl phthalate 10%, the three are fully mixed and dissolved and enter the blending kettle, and then add 2% of alkylphenol polyoxyethylene ether to the blending kettle , polyol fatty acid ester and its ethylene oxide adduct 10%, maleic acid di-sec-octyl sodium sulfonate 4%, antioxidant 2642%, after fully stirring and dissolving, make up to 100% with deionized water %, continue to stir until transparent, and prepare 5% Cyazofamido microemulsion.

Embodiment 3

[0021] Example 3: Cyazofamid 10%, cyclohexanone 10%, dimethylformamide 25%, the three are fully mixed and dissolved and enter the blending kettle, and then add di-sec-octyl maleate sulfonic acid to the blending kettle Sodium 13%, alkylarylphenol polyoxyethylene ether phosphate 6%, sodium sulfate 0.1%, after fully stirring and dissolving, make up to 100% with deionized water, continue stirring until transparent, and prepare 10% Cyazofamida microemulsion.

[0022] The Cyazofamido microemulsion product of the invention has stable performance, is easy to produce and store, is environmentally friendly and safe to use. Tests have proved that it has good control effects on downy mildew, blight, clubroot, damping-off, etc. of vegetables and fruit trees, and the average control effect is over 90% 10 days after application; it is safe and effective for crops No phytotoxicity, it is a pollution-free agricultural fungicide worthy of popularization and application.

Abstract

The invention discloses a cyazofamid microemulsion and a preparation method thereof. The cyazofamid microemulsion comprises the following components by weight percent: 1-10 percent of cyazofamid, 5-60 percent of solvent and co-solvent, 5-20 percent of emulsifier, 1-5 percent of stabilizer, and the balance of deionized water. The preparation method comprises the following steps: completely resolving the cyazofamid active component by the solvent and co-solvent, adding the solution to a mixing kettle, then adding a certain proportion of emulsifier, stabilizer and deionized water, and fully mixing to obtain the cyazofamid microemulsion. According to the invention, the purposes of high efficiency, low toxicity, environmental friendliness, security of human and livestock, and high activity to crop diseases are achieved, the production process is simple and processing and production are easy.

Description

technical field [0001] The invention relates to an agricultural bactericide and a preparation method thereof, in particular to a microemulsion of Cyazofamida and a preparation method thereof. Background technique [0002] Cyazofimazole is a sulfimidazole fungicide, a protective fungicide, and has special effects on downy mildew, blight, clubroot, damping-off, etc. The mechanism of action is to block the electron transfer of the mitochondrial cytochrome bc1 complex in the oomycete pathogens to interfere with the energy supply. Its binding site is the Q1 center of the enzyme, and it has no cross-resistance with other fungicides. Its high selective activity against pathogenic bacteria may be due to the difference in the sensitivity of the target enzyme to the drug. It has high biological activity against Oomycete fungi such as Peronospora, Pseudomonas, Phytophthora, Pythium and Plasmodium brassicae. [0003] Pesticide dosage forms such as emulsifiable concentrate and powder h...
