Abstract

The invention discloses a metarhizium anisopliae and fenoxycarb compound insecticide and application thereof. The insecticide is prepared from metarhizium anisopliae, fenoxycarb and acceptable auxiliary materials of the insecticide. The insecticide disclosed by the invention has an obvious synergistic effect and insect-killing toxicity on each single dosage can be remarkably improved; the insecticide has good insecticidal activity on defoliating pests of indigenous broad leaved trees including camphor trees and the like and good compatibility with the environment, is widely applied and has important meaning on improvement of an ecological environment and improvement of human health levels. The insecticide has the advantages that a production technology is simple, the dosage of pesticide can be greatly reduced and the drug resistance of injurious insects is delayed and has a remarkable effect on pollution-free prevention and control and lasting comprehensive prevention and control on the injurious insects.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a compound insecticide of metarhizium anisopliae and fenoxycarb and its application. Background technique [0002] Native broad-leaved trees are zonal vegetation in subtropical regions of my country, with complex structure, high diversity, strong stability, great potential for development, and important characteristics of ecological security. It plays an important role in water conservation, soil and water conservation, environmental protection and maintenance of terrestrial ecological balance. With the continuous increase in the area of ​​camphor and other broad-leaved tree plantations, as well as the large-area single tree species and plantation pure forest model, the prevalence of pests and diseases has shown an upward trend, and some common pests and diseases may rise to become major pests and diseases. Serious occurrence and prevalence . The types...
