Problems solved by technology

[0003] Existing publications disclose the use of many crystal growth inhibitors, but they still cannot meet the needs of agricultural production. Therefore, in order to change the limitations of the existing crystallization inhibitor technology, it is necessary to further develop effective crystallization inhibitors.

preparation example Construction

[0020] The preparation method of the azole-containing pesticide solution: Weigh each component according to the ratio of each component of the formula, first add one or several kinds of double-substituted long-chain alkyl amides and other solvents into the mixing kettle, open the Stir, then add one or several kinds of azole pesticides into the mixing tank, continue stirring for about half an hour until all the active ingredients of azole pesticides are completely dissolved, then add emulsifier and continue stirring for about one hour until completely homogeneous , stop stirring. Sampling and analysis, according to the national standard requirements on pesticide liquid products, after passing the inspection, the desired product can be obtained.

[0021] Crystallization inhibition effect test method: Dilute and spray the prepared azole pesticide liquid with water, according to the weight ratio of the active ingredient in the diluent from 0.0001 to 3%, here we choose the weight r...

[0026] Through the comparison test of crystallization inhibition, it can be clearly seen that the products added with disubstituted long-chain alkylamides have no crystallization in the diluent, and there is no clogging of filters and nozzles during spray use; The product added with this crystal growth inhibitor will crystallize in the diluent, and the spray cannot be sprayed because the crystallization blocks the filter and nozzle during the spraying process. It shows that disubstituted long-chain alkyl amides have...

Abstract

The present invention relates to an application of disubstituted long-chain alkylamides as crystallization inhibitor in oxazoles pesticide liquid preparation. It is characterized by that one kind or mixture of several kinds of disubstituted long-chain olkylamides can be added in the pesticide liquid preparation containing oxazoles, and can be used for inhibiting crystallization of active component in the pesticide liquid preparation. Said invention also provides the structural formula of said disubstituled long-chain alkylamides.

Description

technical field [0001] The present invention relates to the application of one or several disubstituted long-chain alkylamides as crystallization inhibitors in azole pesticide liquids, so that the water spray liquid of the azole pesticide liquids can inhibit the crystallization of active components of pesticides method. Background technique [0002] The most common way to apply azole pesticides to plants is to spray the water dilution of the pesticide liquid on the plants. Spray equipment is commonly used. The spray equipment contains one or more filters and nozzles. When spraying, if the active Components are water-insoluble solids, filters and nozzles can clog due to precipitation of active components in water. Among them, azole pesticides are a kind of active components with little solubility in water. For azole pesticides, the specific method to overcome the above problems is to add a crystallization inhibitor to the azole pesticide liquid, and when it is diluted with ...
