Abstract

The invention discloses emamectin-benzoate water dispersible granules and a preparation method thereof. The formula comprises the following components in percent by weight: 0.1-30% of emamectin-benzoate raw drug, 5-10% of adhesive, 7-13% of dispersing agent, 1-3% of wetting agent and the balance of filler. The preparation method comprises the following steps of: fully and uniformly mixing the emamectin-benzoate raw drug, the dispersing agent, the wetting agent and the filler, crushing to target particle diameter, spraying aqueous solution of the adhesive to carry out kneading, carrying out granulation, drying and sieving after kneading to prepare a finished product of the emamectin-benzoate water dispersible granules. The emamectin-benzoate water dispersible granules and the preparation method disclosed by the invention have the beneficial effects that the drug effect is not influenced, meanwhile the finished-product yield is greatly increased to 95-97% or above, the dust generation amount is reduced, the loss is reduced and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a water-dispersible granule of emamectin benzoate and a preparation method thereof. Background technique [0002] Water-dispersible granules (WG, WDG) are granular preparations that can quickly disintegrate and disperse into a suspension after adding water. Because of their good safety, no dust, and convenient packaging and transportation, they have become a pesticide in recent years. Environmentally friendly new dosage forms. [0003] Emamectin benzoate water dispersible granule is currently one of the few new, high-efficiency, low-toxicity, safe, pollution-free and residue-free biological insecticides and acaricides that can replace five highly toxic pesticides in the world. High, broad insecticidal spectrum, with stomach poisoning and contact killing effects. It has the highest activity against mites, Lepidoptera, and Coleoptera pests, and is safe for humans and animals, and can be...
