Problems solved by technology

[0007] 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 two kinds of pesticides can not only delay the occurrence of resistance, but also improve the efficacy and residual period, reduce the amount of use, and reduce the cost. Therefore, we use the combination of spinosad and Zhongbucarb to expand the insecticidal spectrum

Abstract

The invention relates to an insecticidal composition consisting of spinosad and fenobucarb. The insecticidal composition comprises 0.5 to 10 percent of spinosad and 1 to 35 percent of fenobucarb. The insecticidal composition has good prevention and control effects on plutella xylostella, reduces using amount, delays medicament resistance, reduces pollution to the environment and does not cause chemical injury easily.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition of spinosyn and secbutacarb. Background technique [0002] Spinosyn, also known as spinosad (Spinosad), is a macrolide pollution-free and efficient biopesticide extracted from the fermentation broth of Saccharomyces spinosa. The spinosyn-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,...
