Abstract

The invention provides a slow-release pesticide granule, which is prepared by the following steps of: uniformly mixing a pesticide active component, cellulose, a surfactant, a cross-linking agent and a filling material according to a certain ratio, and crushing; then slowly adding a product into a circular-disc granulator and introducing water steam; introducing the steam while slowly adding materials to granulate; or slowly adding the product into the circular-disc granulator with a heating device, and adding the materials, spraying water and heating to granulate; after the granulation is finished, closing the steam or stopping water spraying, and rolling in a circular disc for 10-30 minutes; and finally, drying, cooling and sieving, and packaging qualified products to obtain the slow-release pesticide granule. The slow-release pesticide granule disclosed by the invention has the advantages of being simple in preparation method and small in equipment investment; and the aim of introducing the steam into the materials on the circular disc or spraying the water into the circular-disc granulator with a heating function, and heating is realized so as to gelatinize and crossly link the cellulose, the pesticide active component, the cross-linking agent, the surfactant and the filling material, and the first-pass yield of the product is improved.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to a slow-release pesticide granule. Background technique

[0002] The pesticide is made into a kind of pesticide that is measured as necessary, and it can reach the required place continuously and stably within a certain period of time, ensuring that there is a sufficient duration of effect that is basically the same as the growth period of the applied crops, reducing the number of pesticide applications, and reducing the impact of pesticides on the environment. Minimizing the pollution of pesticides is the direction of current research on pesticide preparations, and it is a necessary measure to achieve food stability, increase production and food safety. The pesticide formulations with the above functions can only be possessed by solid sustained-release pesticide granules. Because there are three ways to apply liquid slow-release pesticides to crops. 1. Spraying, 2. Root irrigation, 3....
