Abstract

The invention discloses a thifluzamide oil suspension and a preparation method thereof. The thifluzamide oil suspension takes thifluzamide, a solvent, a thickener, a dispersant and a PH regulator as raw materials. The preparation method of the thifluzamide oil suspension comprises the following steps: firstly, carrying out pretreatment to thifluzamide and the thickener, then stirring all the raw materials by mixing together, throwing into a sand mill to be ground to a particle size below 5 mu m, adding the PH regulator and filtering at last so as to obtain the thifluzamide oil suspension. The quality analysis results of the product show that the decomposition rate of active ingredients is less than 3%, the suspension rate is more than 90%, phenomena of precipitation, agglomeration and stratification do not exist in low-temperature storage, the stability of the thifluzamide oil suspension is qualified, and phenomena of precipitation, agglomeration and stratification are not generated in heat storage at the temperature of 54+/-2 DEG C for 14 days. The thifluzamide oil suspension has simple formula and production process, convenience for use and low production cost and adopts domestic additives completely; an organic solvent is not used to greatly lower the environmental pressure; and the control effect for rice sheath blight, false smut, wheat sheath blight and loose smut of cereal crops is better.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a thifuramide oil suspension, its use and preparation method. Background technique [0002] Thiofuramide belongs to the broad-spectrum fungicides of thiazole amides, which has strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. Due to its fluorine content, it has strong competitiveness in biochemical processes, and it is not easy to recover once combined with substrates or enzymes. Thiofuramide is active against pathogenic fungi such as Rhizoctonia, Puccinia, Stiltia, Tilletia, Puccinia, and Sclerotinia, especially for fungi caused by Basidiomycetes. Diseases such as sheath blight and blight have special effects. In particular, Thiofuramide overcomes many negative and unsafe characteristics for crops currently used to prevent and control smut in the market, and will play a greater role in seed treatment and c...
