Problems solved by technology

At present, the main dosage forms of diflubenzuron are low-concentration suspension concentrates, wettable powders, and emulsifiable concentrates. These dosage forms have disadvantages such as low drug content, inconvenient transportation, and unfriendly to the environment. Therefore, it is more conducive to the development of better dosage forms of the drug. Development and use of this drug
Water-dispersible granules are easy to use, do not use organic solvents, and can increase drug content and efficacy.

Abstract

The invention discloses Hexaflumuron water dispersible granules and a preparation method thereof. The Hexaflumuron water dispersible granules are composed of the following components: in percent by weight, 5-90% of Hexaflumuron, 1-15% of a dispersing agent, 1-8% of a wetting agent, 1-50% of a disintegrant, 0.5-4% of a chelating agent and 100% of filler. The problems that dust can be generated easily by wettable powder, lots of aqueous mediums are contained in a suspending agent, and organic solvents are contained in missible oil. The Hexaflumuron water dispersible granules has high content ofactive ingredients, a high suspension rate, excellent product efficacy, a simple preparation method and convenient operation, industrial continuous production can be achieved, and low transportation cost and environmental safety are achieved.

Description

technical field [0001] The invention relates to a diflubenzuron water-dispersible granule and a preparation method thereof, belonging to the technical field of pesticide preparations. Background technique [0002] At present, the technical development directions in the field of pesticide preparation processing are mainly: higher environmental safety, lower transportation costs, less organic solvents or water media, better drug efficacy, and higher content of preparation products. The overall level of research on dosage forms such as high-content environment-friendly water-dispersible granules and dry suspension concentrates in my country is relatively low, while traditional dosage forms such as wettable powders, suspension concentrates, and emulsifiable concentrates are few and far between. There are some unfavorable factors such as being unfriendly to the environment, inconvenient transportation, and organic solvents are harmful to human health. Therefore, it is urgent to in...
