Embodiment 112

[0035] Example 1 12% Abamectin B2a Nitenpyram EC

[0036] Prepared according to the mass percentage of abamectin B2a and nitenpyram at 1:1. Take Abamectin B2a technical 6%, Nitenpyram technical 6%, emulsifier castor oil polyoxyethylene ether 10%, emulsifier calcium dodecylbenzenesulfonate 2%, cosolvent N-methyl Pyrrolidone 10%, S-150 solvent oil to 100%, stirring and dissolving to obtain 12% Abamectin B2a Nitenpyram EC. After inspection, the content of abamectin B2a is 6.1%, and the content of nitenpyram is 6.2%.

[0037] It is also possible to replace nitenpyram with clothianidin or thiamethoxam to form a new embodiment.

Embodiment 2

[0038] Example 2 12% Abamectin B2a clothianidin microemulsion

[0039] Prepared according to the mass percentage of abamectin B2a and clothianidin 1:2. Get Abamectin B2a former medicine 4.0%, clothianidin former medicine 8%, solvent cyclohexanone 10%, cosolvent N-methylpyrrolidone 10%, add emulsifying agent phenylethylphenol polyoxyethylene ether 20%, Mix and stir evenly, add water to make up 100%, and stir to obtain a uniform and transparent 12% avermectin B2a•clothianidin microemulsion. After testing, the content of abamectin B2a is 4.1%, the content of clothianidin is 8.1%, and the cloud point is less than 60 o C, homogeneous and transparent in appearance, good miscibility with water, and qualified cold and hot storage stability.

[0040] It is also possible to replace clothianidin with nitenpyram or thiamethoxam to form a new embodiment.

Embodiment 3

[0041] Example 3 25% Abamectin B2a Thiamethoxam Soluble Liquid

[0042] Prepared according to the mass percentage of avermectin B2a and thiamethoxam at 1:4. 25% Abamectin B2a • Thiamethoxam soluble liquid. Take 5% of the original drug of Abamectin B2a, 20% of the original drug of thiamethoxam, 15% of the emulsifier fatty alcohol polyoxyethylene ether, 10% of the co-solvent N-methylpyrrolidone, and add the solvent dimethyl carbonate to 100%. After stirring and mixing evenly, set aside for 10 hours and filter to obtain 25% abamectin B2a•clothianidin soluble liquid. After inspection, the content of abamectin B2a is 5.2%, the content of thiamethoxam is 20.1%, and the water content is 1.4%.

[0043] It is also possible to replace thiamethoxam with nitenpyram or clothianidin to form a new embodiment.

Abstract

The invention relates to a pesticide composition containing abamectin B2a. The composition comprises available contents of a component A and a component B, wherein the component A is abamectin B2a, the component B is selected from one of thiamethoxam, nitenpyram or clothianidin; the mass part ratio of the component A to the component B is (20 to 1) to (1 to 50); the total mass of the effective components in the preparation accounts for 1 to 80 percent of the mass of the preparation, and the rest of the components are auxiliary components which are allowed and acceptable in the pesticide. The pesticide composition can be prepared in dosage forms of missible concentrate, suspension agents, water dispersible granules, micro-emulsion, soluble concentrate and granules, and is suitable for preventing, killing and treating parasitic nematodes by which plant root systems are damaged, preventing and killing insect pests with piercing sucking mouthparts such as aphid, greenhouse whitefly and the like. The pesticide composition has the remarkable synergistic effect, application target is enlarged, the resistance development of nicotine medicament can be retarded, and the service life is prolonged.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing abamectin B2a, and belongs to the field of pesticide application. Background technique [0002] The research on pesticide composition is of great significance for prolonging the service life of new pesticide varieties, alleviating the resistance of target organisms, expanding the control spectrum, reducing control costs, improving drug efficacy and environmental safety, etc. Therefore, all countries in the world attach great importance to the research on pesticide mixing. [0003] Abamectin is a class of sixteen-membered macrolide compounds with insecticidal, acaricidal and nematicidal activities. As a relatively mature biopesticide product, in the past few decades, abamectin has mainly studied B1A. However, current research at home and abroad shows that B2a also has great application value. At present, some domestic manufacturers have obtained the p...
