Abstract
The invention relates to a pesticide composition containing parslane herb and common monkshood mother root extracts, and a preparation method and application thereof, and belongs to the field of pesticides. In order to solve technical problems, the invention provides the pesticide composition containing the parslane herb and common monkshood mother root extracts, and the preparation method and application thereof. According to the pesticide composition containing the parslane herb and common monkshood mother root extracts, active ingredients of the pesticide composition are extracted from 1 weight part of parslane herb and 0.2 to 4 weight parts of common monkshood mother root; the active ingredients are prepared by mixing the parslane herb and the common monkshood mother root and extracting together, or prepared by separately extracting the parslane herb to obtain the parslane herb extract, separately extracting the common monkshood mother root to obtain the common monkshood mother root extract, and mixing the two extracts. The pesticide composition containing the parslane herb and common monkshood mother root extracts has an obvious effect of controlling Lepidoptera pests, and has positive significance for agricultural production.
