Embodiment 1

[0019] Example 1: Cyanofamidol 2%, cyclohexanone 10%, N-methylpyrrolidone 15%, the three are thoroughly mixed and dissolved, then enter the blending kettle, and then add castor oil polyoxyethylene ether 10%, polyol to the blending kettle Fatty acid esters and their ethylene oxide adducts 4%, benzenesulfonate 4%, pyrogallic acid 2%, fully stirred to dissolve, deionized water to make up to 100%, continue to stir until transparent, to obtain 1 % Cyanofamidole microemulsion.

Embodiment 2

[0020] Example 2: Cyanofamidazole 5%, ethyl acetate 15%, diethyl phthalate 10%, the three are thoroughly mixed and dissolved, then enter the blending kettle, and then add 2% alkylphenol polyoxyethylene ether to the blending kettle , Polyol fatty acid esters and their ethylene oxide adducts 10%, sodium di-secondary octyl maleate sulfonate 4%, antioxidant 2642%, after fully stirring and dissolving, deionized water makes up to 100%, continue to stir until transparent, to prepare 5% cyanoxazole microemulsion.

Embodiment 3

[0021] Example 3: Cyanofamidol 10%, cyclohexanone 10%, dimethylformamide 25%, the three are thoroughly mixed and dissolved, then enter the blending kettle, and then add di-sec-octyl maleate sulfonic acid to the blending kettle Sodium 13%, alkyl aryl phenol polyoxyethylene ether phosphate 6%, sodium sulfate 0.1%, fully stirred to dissolve, deionized water to make up to 100%, continue to stir until transparent, to prepare 10% cyanefamazole microemulsion.

[0022] The cyanfamazole microemulsion product of the invention has stable performance, is easy to produce and store, is environmentally friendly, and is safe to use. Tests have proved that it has a good control effect on downy mildew, blight, root swelling, damping-off, etc. of vegetables and fruit trees. The average control effect is over 90% 10 days after application; it has good safety and is good for crops. It is non-phytotoxic and 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 cyanoxazole microemulsion and a preparation method thereof. Background technique [0002] Cyanofamidazole is a sulfamidazole bactericide, a protective bactericide, and has specific effects on downy mildew, blight, root edema, damping-off, etc. The mechanism of action is to block the electron transfer of the mitochondrial cytochrome bc1 complex in the oomycete bacteria to interfere with the supply of energy. Its binding site is the Q1 center of the enzyme, which has no cross-resistance to other fungicides. Its high selective activity against pathogenic bacteria may be caused by the difference in sensitivity of the target enzyme to the agent. It has high biological activity against oomycete fungi such as downy mildew, pseudo downy mildew, Phytophthora, Pythium, and Rhizobium brassicae of the Rhizobium class. [0003] Pesticide formulations such as emulsif...
