Abstract

The invention discloses an insecticide compounded by aschersonia aleyrodis and Alpha-cypermethrin, which consists of a main agent and an auxiliary agent. According to the mass percentage, the main agent occupies 32-61% and the auxiliary agent occupies 39-68%; the main agent is the mixture of the aschersonia aleyrodis and the Alpha-cypermethrin with the mass proportion of 100:0.1-0.6; the auxiliary agent is stabilizer, assisting agent and filling material. The compounded insecticide of the invention can be processed into wettable powder, suspension agent or oil agent; according to long-term infection biological study and indoor biological testing, the aschersonia aleyrodis has extremely strong infection insecticidal effects on a plurality of pests, especially for the pests of piercing-sucking mouthpart. The compounded agent of the invention has excellent control effects on the pests such as whitefly, aphid, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biological insecticide, in particular to an environmentally friendly, pollution-free and residue-free compound insecticide of Ascospora whitefly and beta-cypermethrin. Background technique [0002] Aschersonia aleyrodis Webber is an entomopathogenic fungus. As a living biological pesticide, it has a new mechanism of action different from existing chemical insecticides, has no pollution to the environment, and has no residue. It can be used as a It is an alternative control drug for controlling some insects that are resistant to Bt. A. whitefly has a wide distribution and has a good control effect on piercing and sucking mouthparts pests such as aphids and whitefly. The development and utilization of A. whitefly Spores have important economic significance and broad application prospects. [0003] Beta-cypermethrin (beta-cypermethrin) is a pyrethroid insecticide w...
