Embodiment 1

[0037] Weigh 7.3% cyproconazole, 18.2% azoxystrobin, dispersant 3% alkylnaphthalene sulfonate (TERSPERSE2425), emulsifier 2% sorbitan stearate (Span-60#), 2% Polyoxyethylene sorbitan stearate (Tween-60#), wetting agent 1% sodium lauryl polyoxyethylene ether sulfate, thickener 2% bentonite, antifreeze agent 5% ethylene glycol, disinfectant Foaming agent 0.2% simethicone defoamer, stabilizer 1% epichlorohydrin, non-aqueous dispersion medium soybean oil added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill until the particle size was less than 5 microns to prepare 25.5% cyproconazole · azoxystrobin dispersible oil suspension concentrate.

Embodiment 2

[0039] Take by weighing 6% cyproconazole, 15% azoxystrobin, dispersant 2% polycarboxylate (TERSPERSE 2700 produced by Huntsman, U.S.), emulsifier 2% sorbitan stearate (Span- 60#), 3% castor oil polyoxyethylene ether (BY-125), wetting agent 1% disodium alkylphenol polyoxyethylene ether sulfosuccinate, thickener 2% magnesium aluminum silicate, antifreeze 4% propylene glycol, defoamer 0.2% polyether modified silicone defoamer (trade name: s-29 Nanjing Sixin Applied Chemicals Co., Ltd.), stabilizer 10% epoxy soybean oil, non-aqueous dispersion medium oleic acid Methyl esters are added to 100% by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 20 minutes, and sand-milled with a sand mill until the particle size was less than 5 microns to prepare 21% cyproconazole·azoxystrobin dispersible oil suspension concentrate.

Embodiment 3

[0041]Weigh 10% cyproconazole, 25% azoxystrobin, dispersant 3% alkylnaphthalene formaldehyde condensate sulfonate, emulsifier 2% polyoxyethylene ether oleoyl alcohol ester, 3% castor oil polyoxyethylene ether (BY-110), wetting agent 2% alkylphenol polyoxyethylene ether formaldehyde condensate sodium succinate sulfonate, thickener 1% silica, 2% bentonite, antifreeze 4% glycerin, defoaming agent Agent 0.3% polyether modified silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), stabilizer 1% sodium sorbate, and non-aqueous dispersion medium corn oil were added to 100% by weight. The above-mentioned raw materials are mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill until the particle size is less than 5 microns to prepare 35% cyproconazole·azoxystrobin dispersible oil suspension concentrate.

Abstract

The invention discloses a dispersible oil suspension agent containing cyproconazole. The dispersible oil suspension agent is prepared by effective active compositions including cyproconazole and azoxystrobin and a wetting agent, a dispersant, an emulsifying agent, a thickening agent, a stabilizing agent, an anti-freezing agent, a defoaming agent and non-aqua-system dispersing media, wherein the weight proportions of the compositions include that the cyproconazole ranges from 0.5% to 10%, azoxystrobin ranges from 5% to 30%, the wetting agent ranges from 0.5% to 3%, the dispersant ranges from 0.5% to 8%, the emulsifying agent ranges from 0.5% to 10%, the thickening agent ranges from 1% to 6%, the stabilizing agent ranges from 0.5% to 20%, the anti-freezing agent ranges from 1% to 5%, the defoaming agent ranges from 0.1% to 2% and the rest are the non-aqua-system dispersing media. The two active compositions can be mixed to prepare the dispersible oil suspension agent, thereby preventiveeffect of the dispersible oil suspension agent is enhanced, effective period is prolonged, and preventive effective of the dispersible oil suspension agent is obviously better than other agents prepared by the active compositions. Besides, the dispersible oil suspension agent is safe to crop and environment, application dose of agents is reduced, cost is saved, and the dispersible oil suspension agent meets the safety requirement of agrochemicals.

Description

technical field [0001] The invention relates to a dispersible oil suspension containing cyproconazole and a preparation method thereof, belonging to the technical field of compound pesticides. Background technique [0002] Dispersible oil suspension refers to a pesticide formulation that uses oil that does not pollute crops as a carrier, and the oil can be vegetable oil and its derivatives. Oils are taken from natural plants, which are friendly to crops and the environment as diluents, and the oil itself has good adhesion and spreadability, and is easy to adhere to waxy or smooth leaf surfaces, with adhesiveness It has the advantages of good spreadability and strong rain erosion resistance, thereby improving the utilization rate of pesticides, while common pesticide formulations such as wettable powders and powders have dust pollution; EC is not friendly to the environment because it contains a large amount of organic solvents; water dispersion Granules, water suspension co...
