Biopesticide composition for preventing and treating strawberry red spiders

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a biopesticide composition for preventing and treating strawberry red spiders. The invention relates to a biopesticide composition. The biopesticide composition is formed by compounding sanguinarine and spinetoram or rotenone, wherein the mass ratio of sanguinarine to spinetoram is (1-3): (40-1); the mass ratio of sanguinarine to rotenone is (1-10): (10-1). The biopesticide sanguinarine with insecticidal activity is compounded with spinetoram or rotenone, the compounded formula shows a combined synergistic effect on strawberry red mites within a certain mass ratio range, compared with a single component, the control effect on strawberry red mites can be improved, and the control effect on strawberry red mites can be improved. A support can be provided for developing a biological agent for preventing and treating strawberry red spiders.
