Problems solved by technology

[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 , thiazole zinc 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

Embodiment Construction

[0015] The dry suspension provided by the present invention as a compound plant fungicide is prepared as a dry suspension, consisting 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 wi...

Abstract

The invention discloses a dry suspension serving as a compound plant fungicide. The dry suspension is prepared from at least one dry suspension auxiliary material, and zinc thiazole and 4-methyl-1,2,3-thiadiazole-5-o-bromophenol ester formate in a mass ratio of 1 to (0.08-0.12), wherein the dry suspension auxiliary material is prepared from a dispersant, a moistening agent, a disintegrating agent, a bonding agent, an antifoaming agent, water and the balance of filler; the filler is kaolin.

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. Contents of the invention [0003] We are surprised to find that when a certain proportion of specific thiadiazole derivatives is used for compatibility with thiazole zinc, the antibacterial effect of thiazole zinc can...
