Abstract
The invention discloses etofenprox emulsified powder and a manufacture method thereof, relating to an agricultural insecticide and a manufacture method thereof. The etofenprox emulsified powder is prepared from the following raw materials by weight percent: 5-30% of etofenprox, 8-15% of wetting and dispersing agent, 1-6% of solvent and the balance of carrier. The process has the steps that: (1) weighting and taking the raw materials based on the above weight percent; (2) evenly mixing the etofenprox and solvent, enabling the evenly-mixed liquid to be absorbed on carriers, then evenly mixing with the wetting and dispersing agent; and (3) crushing the mixed raw materials by a jet mill, and enabling the particle diameter thereof to satisfy the condition that 98% of particles can pass through sieve pores of 45mu m. Another manufacture method is to evenly mix the etofenprox, the solvent and the wetting and dispersing agent and lead the mixed liquid to be absorbed on the carriers. The etofenprox emulsified powder provided by the invention has the advantages of safety, environment protection, stable storage and good disinfestation effect, can be used for preventing and curing rice plant hoppers, rice water weevil and Cruciferae vegetable vegetables cabbage caterpillars.
Description
Technical field
