Embodiment 1

[0031] Example 1 : Based on the total weight of the granules, active ingredients thiazophosphine 10%, metalaxyl 0.3%, dispersing aid corn starch 0.5%, slow-release agent polyvinyl alcohol 0.1%, binder polyethylene glycol 0.1%, carrier A mixture of 70-80% attapulgite particles and the rest filler calcium bicarbonate and white kaolin.

[0032] See figure 1 As shown, according to the granule preparation method of the present invention, thiazophosphine, metalaxyl, dispersing aid, and slow-release agent are metered and mixed evenly, and the attapulgite particles are used for adsorption to obtain a carrier material. Qualified analysis causes formulating a plan to re-adsorb, and after passing the test, it is ready for use; after mixing the filler, dispersing aid, and binder evenly, the coated material is prepared for use, and finally the carrier material and the coated material are granulated by the coating method. Dry at 110°C to 120°C until the water content of the granules is ...

Embodiment 2

[0033] Example 2 : Based on the total weight of the granules, active ingredients thiazophosphine 8%, metalaxyl 0.2%, dispersing aid corn starch 0.5%, slow-release agent polyvinyl alcohol 0.1%, binder polyethylene glycol 0.1%, carrier A mixture of 70-80% attapulgite particles and the rest filler calcium bicarbonate and white kaolin.

[0034] See figure 1 As shown, according to the granule preparation method of the present invention, thiazophosphine, metalaxyl, dispersing aid, and slow-release agent are metered and mixed evenly, and the attapulgite particles are used for adsorption to obtain a carrier material. Qualified analysis causes formulating a plan to re-adsorb, and after passing the test, it is ready for use; after mixing the filler, dispersing aid, and binder evenly, the coated material is prepared for use, and finally the carrier material and the coated material are granulated by the coating method.

Abstract

The invention relates to a thiazole phosphine and metalaxyl granule and a preparation method thereof. The thiazole phosphine and metalaxyl granule includes the components by weight: 0.1%-20% of thiazole phosphine, 0.1%-5% of metalaxyl, 70%-80% of carrier attapulgite particles, 0.5%-3% of a dispersing agent, 0.1%-2% of a sustained-release agent, 0.1%-5% of a binder, and the balance a filler. The granule of the present invention is granulated by a film coating method. The invention effectively combines the control of plant nematodes and soil-borne diseases, uses resources efficiently, scientifically and rationally, has important significance on environment protection, and plays a positive role in reducing agricultural inputs and promoting agricultural output and income.

Description

technical field [0001] The invention relates to a pesticide granule and a preparation method thereof, in particular to a thiazophosphine and metalaxyl granule and a preparation method thereof. Background technique [0002] Thiazophosphine, whose English name is fosthiazate, has contact and systemic effects, and can be absorbed by plant roots and conducted upwards. It has low toxicity and meets the export standards of agricultural products. It is mainly used to control nematodes and aphids, and has special effects on root-knot nematodes and root-rot nematodes. [0003] Metalaxyl, the English name metalaxyl, is an inhibitor of ribosomal RNA I synthesis, which mainly inhibits the synthesis of proteins in the mycelium of pathogenic bacteria, causing them to lack nutrients, unable to grow normally and die. A fungicide with systemic properties, has protective and therapeutic effects, and has two-way conduction properties. It is mainly used for soil disinfection and control of soi...
