Embodiment 1

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

Embodiment 2

[0020] Example 2: 5% benthiazil, 15% ethyl acetate, and 10% diethyl phthalate, the three are fully mixed and dissolved, then enter the blending kettle, and then add alkylphenol polyoxyethylene ether 2 to the blending kettle %, polyol fatty acid ester and its ethylene oxide adduct 10%, maleic acid di-sec-octyl sodium sulfonate 4%, antioxidant 264 2%, after fully stirring and dissolving, make up with deionized water to 100%, continue to stir until transparent, and prepare 5% benthiazil microemulsion.

Embodiment 3

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

Abstract

The invention discloses a benthiavalicarb-isopropyl microemulsion and a preparation method thereof. The benthiavalicarb-isopropyl microemulsion comprises the following components by weight percent: 1-10 percent of benthiavalicarb-isopropyl, 5-60 percent of solvent and co-solvent, 5-20 percent of emulsifier, 1-5 percent of stabilizer, and deionized water. The preparation method comprises the following steps: completely resolving the benthiavalicarb-isopropyl 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 benthiavalicarb-isopropyl microemulsion. According to the invention, environmental pollution is reduced, the protection of the ecological environment is facilitated, the manufacturing cost is greatly lowered, low toxicity in processing and producing pesticides is achieved and the security and the healthiness of human and livestock are guaranteed.

Description

technical field [0001] The invention relates to an agricultural fungicide and a preparation method thereof, in particular to a benthiazil microemulsion and a preparation method thereof. Background technique [0002] Benthiopyram has a good bactericidal activity against Phytophthora, and it has a good inhibitory effect on sporangia formation and sporangial germination at low concentrations, but has no effect on the release of zoospores and the movement of zoospores. effect. Field trials with Plasmopara viticola Berl, Pseudoperonospora cubensis Rostov. and Peronospora parasitica Fr. showed similar results. The biochemical mechanism of action of benthiazil is under investigation. Benthiopyram is effective against P. infestans infestans resistant to benzamide functional groups and downy mildew of melons resistant to methoxyacrylate functional groups. Activity, it is speculated that the mechanism of action of benthiazil is different from that of fungicides containing these func...
