Embodiment 1

[0039] (1) Raw material ratio: Trisulfuron-methyl technical 5kg, phenethylphenol polyoxyethylene ether 10kg, nonylphenol polyoxyethylene ether phosphate 10kg, JFC 3kg, white carbon black 2kg, xanthan gum 0.02kg, ethyl alcohol Glycol 5kg, silicone defoamer 0.1kg, salad oil 64.88kg.

[0040] (2) Preparation process: add all 10kg of phenylethylphenol polyoxyethylene ether, 10kg of nonylphenol polyoxyethylene ether phosphate, 3kg of JFC, 5kg of ethylene glycol, 0.1kg of silicone defoamer, salad Oil 64.88kg, high-shear stirring for 30 minutes until the materials are evenly mixed. Then add 5 kg of tribenuron-methyl, 2 kg of white carbon black, and 0.02 kg of xanthan gum under stirring, and stir for 1 hour. Afterwards, the material is sanded in a sand mill to make the material diameter meet the specified requirements (generally, the average particle diameter is below 3 microns). Finally, the material is transferred to the reactor, and various indicators are tested according to the ...

Abstract

The invention relates to a tribenuron-methyl oil flowable concentrale and a preparation method thereof. The tribenuron-methyl oil flowable concentrale comprises the following components in parts by weight: 1-35 parts of tribenuron-methyl technical product, 10-45 parts of wetting dispersant, 0.5-10 parts of penetrating agent, 0.1-2 parts of thickener, 0.5-5 parts of antifreezing agent, 0.1-5 partsof defoaming agent and the balance dispersion medium.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and more specifically relates to a novel trisulfuron-methyl oil suspension and a preparation method thereof. Background technique [0002] The generic name of tribenuron-methyl (acid is tribenuron; methyl ester is tribenuron-methyl), and the chemical name is 2-[4-methoxy-6-methyl-1,3,5-triazin-2-yl ( Methyl)carbamoylsulfamoyl]benzoic acid or methyl ester. Tribesulfuron-methyl is a sulfonylurea systemic conduction post-emergence selective herbicide. After the stems and leaves are treated, they can be absorbed by the stems, leaves and roots of weeds, and conduct in the body. By hindering acetolactate synthase, valine, Isoleucine biosynthesis is inhibited, preventing cell division and causing weed death. Dicotyledonous weeds chickweed, shepherd's purse, wheat bottle grass, Maijiagong, ion grass, pig's scorpion, broken rice shepherd's head, Bugweed, Polygonum curcumulus, etc. are sensitive to tr...
