Fenoxanil water dispersible granules

Abstract

The invention belongs to the technical field of farm chemicals and discloses fenoxanil water dispersible granules, which comprise the following ingredients by mass percentage: 10 to 80 percent of fenoxanil, 3 to 12 percent of wetting agent, 3 to 12 percent of dispersant, 0 to 10 percent of disintegrant, 0.1 to 3 percent of binder and 5 to 84 percent of filler. The ingredients are mixed in proportion, stirred uniformly and crushed to form high concentration dust; the high concentration dust is uniformly mixed with the binder; and the mixture is granulated, and the grains are dried and sieved to obtain the fenoxanil water dispersible granules. The fenoxanil water dispersible granules overcome the drawbacks of suspending agents and wettable powders, reduce environmental pollution and are mainly used for preventing and controlling magnaporthe grisea.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, in particular to a water-dispersible granule of blastamide. Background technique: [0002] Fenoxanil (fenoxanil) is an amide fungicide jointly developed by BASF and Japan Agricultural Chemical Company, the chemical name is N-(1-nitrile-1,2-dimethylpropyl)-2-(2,4-dichloro Phenoxy) propionamide, the structural formula is: [0003] [0004] Blasticamide has good systemic and residual activity, and is an inhibitor of melanin biosynthesis. It is used to control rice blast and is safe for crops, mammals and the environment. [0005] Rice blast is one of the three important diseases of rice. It is widely distributed in various rice regions in the world. It occurs to varying degrees in the northern and southern rice regions of my country every year, especially in the southern mountainous rice fields. Rice can be affected throughout the growth period. Due to the different periods and parts of th...

AI Technical Summary

Problems solved by technology

[0006] At present, the dosage form of rice blastamide in the market is suspension concentrate. Although the suspension concentrate is an environmentally friendly preparation, its storage stability is an important performance index. It is related to the performance and application effect of the product, and the factors affecting stability are relatively large Many, high requirements on the concentration of the original drug, additives, and pH value, and the suspending agent is prone to stratification or precipitation if it is left for a long time, which will affect the efficacy of the drug
