Embodiment Construction

[0015] The compound thiadiazole plant fungicide provided by the invention is prepared as a dry suspension and consists of compound (I), compound (II) and at least one auxiliary material suitable for dry suspension. The formula of the composition is shown in Examples 1 to 4 in the following table respectively (the percentage shown in the table is the mass percentage accounting for the total mass of the composition):

[0016]

[0017] The compounding method of described composition is:

[0018] 1) Add all components except water into the batching tank according to the ratio, add water to slurry, and stir evenly;

[0019] 2) Use a high-speed shearing machine for coarse crushing until the particle size is 100-200 mesh;

[0020] 3) After coarse crushing, use a sand mill to grind to a particle size of 8000-10000 mesh;

[0021] 4) After sanding, it is sent to a pressure spray drying tower for drying and granulation to obtain hollow open-pore spherical particles with a particle s...

Abstract

A compound thiadiazole plant fungicide is characterized by being prepared from at least one auxiliary applicable to the plant fungicide as well as zinc thiazole and 4-methyl-1,2,3-thiadiazole-5-o-cresol formate, wherein the mass ratio of zinc thiazole to 4-methyl-1,2,3-thiadiazole-5-o-cresol formate is 1:(0.05-0.07), the compound thiadiazole plant fungicide is a dry suspension, and the total mass of zinc thiazole and the compound (II) is 15%-30% of the total mass of the compound thiadiazole plant fungicide.

Description

technical field [0001] The invention relates to a fungicide for plants. Background technique [0002] 2-Amino-5-mercapto-1,3,4-thiadiazole zinc (Chinese name thiazole zinc) is a plant fungicide widely used in the control of rice bacterial blight and other plant diseases, but after research it was found that , Zinc thiazole is also a thyroid disruptor, which can cause hyperplasia of thyroid tissue in experimental animals, and its toxicity has obvious dose-effect correlation in the study. As a pesticide, it can cause adverse effects on the health of the applicator and cause pollution in the environment. Therefore, how to reduce its toxicity, or reduce its dosage without affecting the control effect, has become an urgent problem to be solved in the prior art. [0003] Chinese patent CN2010101798244 discloses: 4-methyl-1,2,3-thiadiazole-5-formic acid o-cresol ester and its preparation method, and pointed out in the follow-up pharmacological experiments that the compound is eff...
