preparation example Construction

[0045] And the applicant found that by using the vinyl compound substituted with benzenesulfonate and pyrrolidone as the hydrophilic component in the film-forming agent, while promoting the stability of the film-forming agent in the water system, the thickness of the thickener can be further promoted. And the stability of fluopyram, thiamethoxam and tebuconazole and other original drugs in the heat storage process, in which the large entropy value at higher temperature will promote the stability of fluopyram, thiamethoxam and tebuconazole Dissolution and aggregation of the original drug, as well as the intensification of the movement of magnesium aluminum silicate, etc., this makes the cross network stability of the film forming agent worse, and it is easier to cause particle precipitation than normal temperature, and the applicant found that when using the present invention In the film-forming agent emulsion, the pyrrolidone with similar structure in the long chain of the film...

Abstract

The invention relates to the technical field of pesticides, in particular to a composition containing fluopyram as well as a preparation method and application of the composition. The composition is prepared from the following raw materials: fluopyram, thiamethoxam and tebuconazole. The composition provided by the invention has good bactericidal and insecticidal effects through the combined actionof fluopyram, thiamethoxam and tebuconazole, and has high prevention and treatment effects on corn wireworms, rhizoctonia solani and the like; the applicant can promote the storage stability of fluopyram, thiamethoxam and tebuconazole in a liquid preparation, such as a seed treatment suspending agent, keep a certain viscosity, promote long-time flow and promote the water resistance of a coating film prepared from the composition by limiting auxiliaries such as a film-forming agent, a thickening agent, a wetting dispersant and the like; therefore, the rain wash resistance and the water immersion resistance are improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, more specifically, the invention relates to a composition containing fluopyram and its preparation method and application. Background technique [0002] Fluopyram (ISO common name: Fluopyram), trade name: Lu Fuda; CAS No: 658066-35-4, chemical name: N-{2-[3-chloro-5-(trifluoromethyl)- 2-pyridyl]ethyl}-α,α,α-o-trifluoromethylbenzamide. Fluopyram is an SDHI (succinate dehydrogenase inhibitor) fungicide and nematicide developed by Bayer Crop Science Company, except for grapes, pears, bananas, apples, cucumbers, tomatoes and other vegetables and field crops In addition to the prevention and control of spotted leaf spot, leaf spot, gray mold, powdery mildew, sclerotinia, early blight, etc., it can also be registered on a variety of crops to prevent and control a variety of nematodes. It is an efficient, green, Low toxicity nematicide. Fluopyram is not only a new generation of excellent nematocid...
