Abstract

The invention belongs to the technical field of pesticide preparation, and particularly relates to emamectin benzoate-indoxacarb water dispersible granules and a preparation method thereof. The emamectin benzoate-indoxacarb water dispersible granules are prepared from the following components in parts by weight: 3.7-4.3 parts of emamectin benzoate, 5.7-6.3 parts of indoxacarb, 4-5 parts of diisooctyl phthalate, 3-4 parts of trans-2-hexenol, 3-4 parts of alpha-pinene, 1-2 parts of sucrose ester, 1-2 parts of hexyl acetate, 2-4 parts of syrup, 5-10 parts of tea saponin, 12-15 parts of lignosulfonate, 0.2-5 parts of a stabilizing agent, 0.2-3 parts of an attractant, 1-8 parts of an anti-freezing agent, 2-3 parts of a preservative, 10-20 parts of an antifoaming agent, 5-8 parts of an antioxidant, 2-4 parts of an adhesive, 20-25 parts of a disintegrating agent and a proper amount of wood vinegar. The preparation method of the emamectin benzoate-indoxacarb water dispersible granules comprises the following steps: mixing raw materials, then performing fluid energy milling, adding a proper amount of the antifoaming agent and the wood vinegar, and performing granulation, drying and sievingto obtain water dispersible granule products.

Description

technical field [0001] The invention belongs to the technical field of pesticide manufacture, and specifically relates to a water-dispersible granule of caramelvin-indoxacarb and a preparation method thereof. Background technique [0002] Water dispersible granule (WDG) is a new pesticide formulation successfully developed in the 1980s. It is a granulated formulation developed on the basis of pesticide wettable powder and pesticide suspension concentrate. Water-dispersible granules are made by mixing and crushing the active ingredients of pesticides, additives and fillers, and then granulated. Water-dispersible granules quickly disintegrate and disperse after entering water, and can form a high-suspension dispersion system after stirring. In the granulation process, the binding effect of the binder is required, the wetting effect of the wetting agent is required when entering water, the rapid disintegration of the disintegrant is required, and a high-suspension dispersion sy...
