Preparing process of rotenone water emulsion

Abstract

The present invention relates to preparation process of rotenone water emulsion. In temperature of 30-80deg.c, rotenone in 0.1-25 wt %, solvent, and stabilizer in 0.1-3.5 wt % are mixed mechanically in a emulsifying kettle; emulsifier in 5-15 wt % and other assistants are added into water through stirring; and the two kinds of mixture are mixed through stirring in 100-12000 rpm for 5-180 min, andfiltered to eliminate solid impurity to obtain the water emulsion product. Compared with available technology, the rotenone water emulsion as one pesticide preparation has the advantages of environment friendship and capacity of meeting agricultural pesticidal requirement.

Description

technical field The invention relates to the technical field of natural insecticides, in particular to a method for preparing rotenone water emulsion by extracting rotenone, a natural insecticidal active ingredient, from the root of the plant Rotenus radix.
