Abstract

The invention discloses a flufenacet water-dispersible granule and a preparation method thereof. The flufenacet water-dispersible granule is prepared from the following components by weight: 10 to 80% of crude flufenacet, 2 to 6% of a wetting agent, 4 to 15% of a dispersing agent and 0 to 10% of a disintegrating agent, with the balance being a solid carrier, wherein the wetting agent is alkylphenol polyoxyethylene formaldehyde condensate sulfate and / or alkyl naphthalene sulfonat, and the dispersing agent is alkyl naphthalene sulfonic acid-formaldehyde condensate sodium salt and / or polycarboxylate. The water-dispersible granule is rapid in disintegration, has a suspension rate of no less than 85%, a pH value (1% aqueous solution) of 6.0 to 8.0, a wet sieve passing rate of no less than 8% and a lasting foamability index of no more than 40 mL of foam in 1 min, and has qualified stability after hot storage at 45 DEG C for 45 days.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a flufenacet water-dispersible granule and a preparation method thereof. Background technique [0002] Water-dispersible granules, also known as dry suspension concentrates or granular wettable powders, can disintegrate quickly in water to form a high-suspension dispersion system. It has the following advantages: ① No dust, safe for operators; ② Stable physical and chemical properties, especially for pesticides that are unstable in water; ③ Good fluidity, easy to pack, and easy to measure; ④ High active ingredients, dispersed in water Good performance. [0003] The chemical name of flufenacet is 4'-fluoro-N-isopropyl-2-[5-(trifluoroglycoside)-1,3,4-thiadiazo-2-imine]acetamide, which belongs to aromatic Acetamide compounds have a similar weed control spectrum to chloroacetamide herbicides, and can extensively control annual grass weeds, sedges and small...
