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 combination 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 costs. Therefore, we use the combination of spinosyn and buprofezin to expand the insecticidal spectrum.

Embodiment Construction

[0009] The following specific examples are used to further describe the present invention in detail, but the present invention is by no means limited to these following examples. The percentages in the formula are all percentages by weight, and the original drugs and auxiliaries used are purchased from other manufacturers.

[0010] The recipe example is as follows:

[0011] 1. Preparation of suspending agent

[0012] According to the formula requirements, using water as the medium, add the active ingredients, wetting agent, dispersant, thickener, defoamer, etc. into a sand mill for grinding, and then emulsify in a high-shear emulsification kettle to obtain a suspension.

[0013] Formula 1 (25% suspending agent)

[0014] Component Weight percent content

[0015] Spinosad 5%

[0016] Buprofezin 20%

[0017] Sodium Lauryl Sulfate 3%

[0018] Sodium lignosulfonate 4%

[0019] carboxymethyl cellulose 0.2%

Abstract

The invention relates to a pesticide composition containing buprofezin and spinosad. The pesticide composition comprises the buprofezin and the spinosad serving as active ingredients; and a proper amount of auxiliary agents and filler are added into the active ingredients so as to prepare formulations such as wettable powder, suspension, water dispersible granules and the like. The pesticide composition has an obvious synergistic effect of preventing and controlling rice planthopper, and can improve the prevention effect, reduce the using amount, delay pesticide resistance and prolong the duration.

Description

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