Abstract

A composite insecticide in the form of emulsified oil or microemulsion for preventing and eliminating tobacco aleyrodids is proportionally prepared from melarrhizin, abameotin, solvent, emulsifier, and other assistants including co-solvent, synergist, or optional anti-freezing agent.

Description

technical field [0001] The invention relates to a biological insecticide, in particular to a compound insecticide of Metarhizin and Avermectin. Background technique [0002] Detruxin (destruxin) is a secondary metabolite of the entomopathogenic fungus Metarhizium anisopliae var. anisopliae, and is an important pathogenic factor of Metarhizium anisopliae. Metarhizin has biological activities such as insecticidal, anti-virus and anti-cancer, and has a new mechanism of action different from existing insecticides, as well as easy degradation and no residue characteristics. The development and utilization of Metarhizin has important economic significance. Metarhizin A, B and E are the most widely distributed and the highest content of Metarhizin, which have good control effects on aphids, Bemisia tabaci, diamondback moth, etc., and have good application prospects. [0003] Abamectin (abamectin) is a high-efficiency broad-spectrum insecticide widely used at present. It is mainly...
