Problems solved by technology

[0005] At present, the domestic preparations are only in the form of single-dose wettable powder, and there are many research reports on the compound preparations of tebufenfen and other pesticides, such as pyrethrins, pyridaben, etc., such as 11% tebufenfen and Cypermethrin, high-chlorine compound water emulsion, 21% tebufenfen·fenpropathrin EC, the reason is that the drug effect of tebufenfen is not easy to be fully exerted, and multi-species compounding is needed to effectively kill insects. purpose of mite
Such compound combinations often need to waste a lot of pesticides, increase pesticide residues, and cause harm to the environment
At present, there are many kinds of pesticide synergists on the market. When the pesticides are used, they are added by tank mixing. Without the guidance of professional knowledge, it is easy to cause the following consequences: First, improper use of the added synergists will destroy the original The stability of the preparation itself, on the contrary, reduces the efficacy of the preparation.

Embodiment 1

[0024] Example 1: Take 10kg of tebufenpyrad technical substance, and 8kg of xylene solvent in a shearing machine or a homogenizer, stir evenly and drop into 2kg of calcium dodecylbenzenesulfonate, 3kg of alkyl aryl polyoxyethylene ether, 5kg of nonane Base phenol polyoxyethylene ether surfactant, after fully stirring evenly, as the oil phase; then fully mix antifreeze agent 5kg ethylene glycol, 0.1kg xanthan gum, 1kgJFC, 0.5kg water-soluble azone, 65.4kg water Evenly, as the water phase; then add the water phase to the oil phase in batches or slowly while cutting, add 0.3kg of silicone defoamer after the addition is complete, cut for 30 minutes and discharge, and you can get milky white 10 % synergistic tebufenfen water emulsion.

Embodiment 2

[0025] Example 2: Take 15kg of tebufenpyrad technical substance and 10kg of xylene solvent in a shearing machine or a homogenizer, stir evenly and drop into 2kg of calcium dodecylbenzene sulfonate, 4kg of tristyrene phenol polyoxyethylene ether, 4kg of nonane Base phenol polyoxyethylene ether surfactant, after being fully stirred evenly, as the oil phase; then fully mix the antifreeze agent 5kg ethylene glycol, 0.1kg xanthan gum, 2kgJFC, 1kgAOT, 56.9kg water, and use it as the water phase Then, while cutting, add the water phase to the oil phase in batches or slowly, add 0.3kg of organic silicon defoamer after the addition is complete, and cut the material for 30 minutes to obtain 15% milky white synergistic pyrimite Amine water emulsion.

Embodiment 3

[0026] Example 3: Get 20kg of tebufenpyrad technical substance, and 14kg of xylene solvent in a shearing machine or a homogenizer, stir and drop into 2kg of calcium dodecylbenzenesulfonate, 3kg of tristyrene phenol polyoxyethylene ether, 5kg of oil Acid-based polyoxyethylene ether surfactant, after fully stirring, is used as the oil phase; then the antifreeze agent 5kg ethylene glycol, 0.1kg xanthan gum, 2kgJFC, 1kgAOT, 47.9kg water are fully mixed, and used as the water phase ; Then add the water phase to the oil phase in batches or slowly while shearing, add 0.3kg of organic silicon defoamer after the addition is complete, and cut the material for 40 minutes to obtain 20% synergistic pyrimite with a milky white appearance Amine water emulsion.

Abstract

The invention discloses a tebufenpyrad pesticide effect-enhancing water emulsion. The water emulsion is characterized by comprising the following components by weight percent: 10-25% of tebufenpyrad active compound, 1-10% of synergist, 1-20% of emulsifying agent, 1-5% of antifreeze agent, 0-2% of defoaming agent, 1-45% of solvent, 0.1-3% of thickening agent and the balance of water. According to tebufenpyrad pesticide effect-enhancing water emulsion, a large amount of water is taken as the solvent, so that the water emulsion is safe, green and environment-friendly, and is the inexorable trend of the pesticide preparation in 21 century, the conventional mode that the pesticide effect is improved by compounding the pesticide with other conventional pesticides is abandoned, and the special synergist is adopted, so that the effect-enhancing function of the pesticide is improved greatly without increasing the using amount of the pesticide, the cost is saved, the pesticide effect is enhanced, the pesticide residual is lowered, and the environment is protected effectively.

Description

technical field [0001] The invention relates to a preparation method of polyphenyl ring polyether succinate and sulfonate thereof, belonging to the technical field of pesticide preparation and preparation. Background technique [0002] Tebufenpyrad is a pyrazole acaricide developed by Mitsubishi Chemical Corporation and jointly developed with Cyanamid Corporation (commercial name: Pyranica, Cardiac).
