Embodiment 1

[0021] Example 1: benthiazil 5%, xylene alcohol 12%, the two are mixed, fully dissolved to obtain the oil phase; castor oil polyoxyethylene ether 3%, fatty alcohol polyoxyethylene ether 2%, alkylphenol formaldehyde resin 1% polyoxyethylene ether sulfate, 2% pyrogallic acid, 2% peanut oil and 4% ethylene glycol, put them into deionized water together, stir fully in the preparation kettle to make a water phase, turn on the stirring and put the oil phase was slowly added to the water phase, and sheared at 6000 rpm for 30 minutes to obtain a 5% benthiazil emulsion in water.

Embodiment 2

[0022] Example 2: 10% benthiazil, 10% xylene, and 10% diethyl phthalate, the three are mixed and fully dissolved to obtain an oil phase; polyoxyethylene sorbitan fatty acid ketone 2%, polyol 1.5% fatty acid ester and its ethylene oxide adduct, 1% sodium dioctyl maleate sulfonate, 2% antioxidant 264, 4.0g peanut oil and 4% glycerol, put together In deionized water, fully stir in the preparation kettle to make the water phase, turn on the stirring, slowly add the oil phase to the water phase, cut at 6000 rpm for 15 minutes, and prepare 10% benthiazil water emulsion.

Embodiment 3

[0023] Example 3: benthiazil 20%, N-octylpyrrolidone 10%, aromatic hydrocarbon solvent Solvesso150 25%, the three are mixed, fully dissolved to obtain an oil phase; castor oil polyoxyethylene ether 4%, polyoxyethylene dehydration Sorbitol fatty acid ketone 2%, fatty alcohol polyoxyethylene ether 1%, alkylphenol formaldehyde resin polyoxyethylene ether sulfate 1%, epoxy soybean oil 5% and glycerol 4%, after fully stirring in the preparation kettle Prepare the water phase, turn on the stirring, slowly add the oil phase into the water phase, cut at 6000 rpm for 20 minutes, and prepare 20% benthiazil emulsion in water.

[0024] The benthiazil aqueous emulsion of the present invention overcomes the shortcomings of traditional formulations such as emulsifiable concentrates and powders, and has the advantages of environmental protection and low use cost. During processing and use, the pollution to the environment is reduced, and the use cost of farmers is reduced. . Field efficacy t...

Abstract

The invention discloses benthiavalicarb-isopropyl emulsion in water and a preparation method thereof. The benthiavalicarb-isopropyl emulsion in water comprises, by weight percent, 1-20% of benthiavalicarb-isopropyl, 1-45% of solvent and cosolvent, 1-15% of emulsifier, 0.5-2% of dispersant, 1-5% of stabilizer, 1-5% of antifreezing agent, and the balance of deionized water. The preparation method includes dissolving the benthiavalicarb-isopropyl in the solvent and cosolvent, adding the emulsifier, the stabilizer and the dispersant to obtain oil; mixing the antifreezing agent and the deionized water to obtain liquid, and slowly adding the oil into the liquid or slowly adding the liquid into the oil under high shear to obtain the benthiavalicarb-isopropyl emulsion in water. The benthiavalicarb-isopropyl emulsion in water has the advantages of high efficiency, low toxicity, environmental friendliness, safety to human and livestock, less easiness to cause resistance and the like. The benthiavalicarb-isopropyl emulsion in water is simple in preparation process and is easy to produce.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to an aqueous emulsion of benthiazil 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 functional groups. Moreover, be...
