Dispersible oil suspension agent containing cyproconazole

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...

Problems solved by technology

Amistra Xtra is used for cereals in Romania and the United States. In Brazil, it is registered under the trade name of Priori Xtra for the control of Asian soybean rust (Phakoprora pachyrhizi). In the report of the dispersible oil suspension concentrate with strytostrobin as the active ingredient, the inventor unexpectedly found that mixing two types of active ingredients into a dispersible oil suspension concentrate can improve its control effect and prolong its duration, which is significantly higher than that of other formulations made of it. The control effect of the dosage form is safe for crops and the environment, and it can reduce the amount of pesticide application and save costs. Therefore, mixing cyproconazole and azoxystrobin into a dispersible oil suspension will have a good market promotion prospect
