AI Technical Summary

Technical Problem

The formulations of thiophanate-methyl and prothioconazole suspension concentrates in the prior art lack in-depth research, have low active ingredient content, and their performance needs to be improved. Furthermore, there is a lack of systematic formulation screening, resulting in poor performance of the suspension concentrates.

Method used

By screening and optimizing the combination of wetting and dispersing agents and thickeners, a suspension concentrate of thiofuran and prothioconazole was prepared. The formula includes 25-35% thiofuran, 4-8% prothioconazole, 4-10% wetting and dispersing agent, 0.4-2% thickener, 2-5% antifreeze, 0.4-0.8% defoamer and deionized water. It is prepared using a specific process to optimize the dispersibility and stability of the suspension concentrate.

Benefits of technology

The bioavailability and field application effect of the suspension concentrate are improved, the shelf stability is enhanced, and the content of active ingredients and the overall performance of the suspension concentrate are increased.

Abstract

The invention relates to a suspending agent containing thifluzamide and prothioconazole. The formula of the suspending agent comprises thifluzamide, prothioconazole, a wetting dispersant, a thickening agent, an anti-freezing agent, a defoaming agent and deionized water. In the formula, the wetting dispersant is selected from one or two of succinate sulfonate and a maleic acid-acrylate copolymer; the thickening agent is one or two of magnesium aluminum silicate and sodium alginate. According to the invention, a preparation formula with excellent suspension dispersibility, stability and the like is obtained by screening the functional auxiliary agents, especially screening the wetting dispersant and the combination thereof, and screening the thickening agent and the combination thereof, so that the shelf stability of the preparation and the bioavailability after field application can be improved.
