Embodiment 1

[0019] Embodiment 1 contains the selection of trifluoropyrimidine ultra-low volume liquid agent solvent

[0020] Table 1 Physical properties of several solvents

[0021]

[0022]

[0023] Table 1 points out that xylene cannot be used due to high volatility, and vegetable oil has the advantages of low volatility and low phytotoxicity, but poor solubility. Heavy. Through the above-mentioned solvent solubility, volatility, viscosity and crop damage, the preferred solvents are N-methylpyrrolidone, dimethyl sulfoxide, second-line oil and methyl oleate.

Embodiment 2

[0024] Example 2 Preparation of ultra-low volume liquid containing trifluoropyrimidine

[0025] The components include: trifluoropyrimidine 10%, calcium dodecylbenzenesulfonate 2.5%, castor oil polyoxyethylene ether 2.5%, N-methylpyrrolidone 5%, and second-line oil supplement 100%.

[0026] The preparation process is as follows: Weigh the materials according to the above mass percentage, add trifluoropyrimidine, N-methylpyrrolidone and second-line oil into the mixing kettle with agitator to dissolve completely, then add calcium dodecylbenzenesulfonate and castor oil polyoxygenate Vinyl ether is mixed evenly to obtain 10% trifluoropyrimidine ultra-low volume liquid.

Embodiment 3

[0027] Example 3 Preparation of ultra-low volume liquid containing trifluoropyrimidine

[0028] The components include: 20% of trifluoropyrimidine, 2% of calcium dodecylbenzenesulfonate, 2.5% of alkylphenol polyoxyethylene ether, 5% of N,N-dimethylformamide, and 100% of secondary oil.

[0029] The preparation process is as follows: Weigh the materials according to the above mass percentage, add trifluoropyrimidine, N, N-dimethylformamide and second-line oil into the mixing kettle with agitator to dissolve completely, then add calcium dodecylbenzenesulfonate and The alkylphenol polyoxyethylene ether is uniformly mixed to obtain a 20% trifluoropyrimidine ultra-low volume liquid.

Abstract

The invention relates to triflumezopyrim-containing ultra-low volume liquor which is composed of the following components in percentage by weight: 1-80% of triflumezopyrim, 1-15% of aids, 1-10% of a cosolvent and the balance of solvents, totaling 100%. The triflumezopyrim-containing ultra-low volume liquor disclosed by the invention is applicable to ultra-low volume spray, low-volume spray and electrostatic spray, has quick-acting effect, long lasting period, rain wash resistance and resistance difficulty, does not need any water, and does not produce hazards on crops. Compared with other triflumezopyrim dosage forms, the preparation in the invention has the advantages of being low in dose and excellent in effects. The triflumezopyrim-containing ultra-low volume liquor provided by the invention has an excellent effect of controlling paddy delphacidae.

Description

technical field [0001] The invention relates to a trifluoropyrimidine-containing ultra-low volume liquid agent and a preparation method thereof. Background technique [0002] Triflumezopyrim, chemical name: 3,4-dihydro-2,4-dioxo-1-(pyrimidin-5-ylmethyl)-3-(α,α,α-trifluoro m-tolyl)-2H-pyrido[1,2-α]pyrimidin-1-ium-3-salt, which belongs to mesoionic insecticides, acts on nicotinic acetylcholine receptors, but its mechanism of action is different from existing Neonicotinoid insecticides have a good control effect on various piercing-sucking mouthparts pests. [0003] Adults and nymphs of rice planthoppers cluster in the lower part of rice clusters to suck juice; when females lay eggs, they pierce leaf sheaths and leaves with ovipositors, which can easily cause rice plants to lose water or be infected with sclerotinia. The excrement is often caused by mold-causing fungus, which affects the photosynthesis and respiration of rice, and severe rice plants dry up. Commonly known as...
