Insecticidal composition

Abstract

The invention relates to an insecticidal composition, which comprises two active components such as spinosad and azadirachtin. The insecticidal composition has a good control effect on diamond back moth. Due to the adoption of the insecticidal composition, the generation of the drug fastness can be delayed, the environmental pollution can be reduced, and drug hazard is difficult to produce while the dosage is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition of spinosad and azadirachtin. Background technique [0002] Spinosad, also known as spinosad, is a kind of macrolide pollution-free and high-efficiency biopesticide extracted from the fermentation broth of Saccharomyces spinosa. The spinosad-producing parent strain, the soil actinomycete Saccharopolyspora spinosa Metrz & Yao, was originally isolated from an abandoned winery in the Caribbean. Spinosad has a novel mode of action, which can continuously activate the target insect acetylcholine nicotinic receptor, but its binding site is different from that of nicotine and imidacloprid. Spinosad also affects GABA receptors, but the mechanism of action is unclear. It is not known whether there is cross-resistance to other types of insecticides. These compounds can cause rapid death of target phytophagous insects such as caterpillars, leafminers, thrips, and lea...

Problems solved by technology

[0004] Because farmland pests cause great losses to crop production every year, considering the long-term use of a single variety of pesticides, it is easy to promote the resistance of pests and cause greater pollution to the environment. The mixture of different pesticides can not only delay the emergence of resistance, but also improve the efficacy and residual period, reduce the amount of use, and reduce the cost. Therefore, we use spinosad and azadirachtin to expand the insecticidal spectrum.
