Embodiment 1

[0025] An aqueous emulsion containing clodinafop-propargyl 8%, clodinafop-propargyl 2%, xylene 20%, calcium dodecylbenzenesulfonate 5%, AEO-9 5%, hydrochloric acid 0.1%, ethylene glycol 5%, 1% of guar gum, 0.1% of simethicone oil, and the balance is water, all of which are weight ratios.

[0026] Dissolve 0.1% hydrochloric acid, 5% ethylene glycol and 1% guar gum in water to form a water phase; dissolve 8% clodinafop-propargyl and 2% cloclodin-propargyl in an organic solvent, add dodecane Calcium phenyl sulfonate 5%, nonylphenol polyoxyethylene ether (AEO-9) 5%, simethicone 0.1% form an oil phase; the oil phase and the water phase are mixed in an emulsification tank at 100 rpm Stir at a rotating speed for 30 minutes to obtain 8% clodinafop-propargyl emulsion in water.

Embodiment 2

[0028] A water emulsion containing clodinafop-propargyl 8%, clodinafop-propargyl 2%, xylene 10%, mixed benzene 10%, calcium dodecylbenzenesulfonate 5%, AEO-9 5%, hydrochloric acid 0.3%, ethyl alcohol 5% of diol, 1% of carboxymethyl starch, 0.1% of simethicone, and the balance is water, all of which are in weight ratio.

[0029] Dissolve 0.3% hydrochloric acid, 5% ethylene glycol, and 1% carboxymethyl starch in water to form a water phase; dissolve 8% clodinafop-propargyl and 2% clodinafop-propargyl in an organic solvent, add dodecane Calcium phenylsulfonate 5%, AEO-95%, and dimethyl silicone oil 0.1% form an oil phase; mix the oil phase and water phase in an emulsification kettle, and stir at 100 rpm for 30 minutes to obtain 8% alkyne Grass ester aqueous emulsion.

Embodiment 3

[0031] A water emulsion containing clodinafop-propargyl 8%, cloclodin-propargyl 2%, xylene 10%, cyclohexanone 10%, calcium dodecylbenzenesulfonate 5%, Tween-20 5%, hydrochloric acid 0.2% , 5% ethylene glycol, 1% carboxymethyl starch, 0.1% simethicone, and the balance is water, all of which are weight ratios.

[0032] Dissolve 0.3% hydrochloric acid, 5% ethylene glycol, and 1% carboxymethyl starch in water to form a water phase; dissolve 8% clodinafop-propargyl and 2% clodinafop-propargyl in an organic solvent, add dodecane 5% calcium phenylsulfonate, AEO-95%, and 0.1% dimethyl silicone oil form an oil phase; mix the oil phase and water phase in an emulsification kettle, and stir at 150 rpm for 30 minutes to obtain 8% alkyne Grass ester aqueous emulsion.

Abstract

The invention discloses clodinafop-propargyl emulsion in water and a preparation method thereof. The clodinafop-propargyl emulsion in water is characterized by consisting of the following components: 8 percent of clodinafop-propargyl, 2 percent of safener, 20 percent of organic solvent, 10 percent of surfactant, 0.5 percent of pH regulator, 5 percent of anti-freezing agent, 1 percent of thickening agent, 0.1 percent of defoaming agent and the balance of water. Field efficacy trials of Anhui Pesticide Verification Office show that the consumption of the 8% clodinafop-propargyl emulsion in water is 66 milliliters per mu, the control effect of the emulsion in water on annual gramineous weed such as bluegrass, alopecurus aequalis, crabgrass and wild oat is 81.35, the control effect of the emulsion in water on fresh weight is 84.79, the control effect of 8% clodinafop-propargyl missible oil on the weed is 76.89, and the control effect of the missible oil is 80.92. Obviously, the control effect of the clodinafop-propargyl emulsion in water is higher than that of the missible oil product under the same consumption.

Description

technical field [0001] The invention discloses an 8% clodinafop-propargyl emulsion in water and a preparation method thereof. Background technique [0002] Clodinafop-propargyl, English name Clodinafop-propargy), alias: clodinafop-propargyl, clodinafop-propargyl, CAS number: 105512-06-9, chemical name: (R)-2-[4-(5-chloro-3- Fluoro-2-pyridyloxy)phenoxy]-propionic acid propyl ester. [0003] Clodinafop-propargyl is an excellent wheat field herbicide, which mainly controls annual grass weeds. At present, the main dosage forms of clodinafop-propargyl are emulsifiable concentrate and wettable powder, which are polluted by organic solvents and dust. Contents of the invention [0004] In order to solve the problem that the existing clodinafop-propargyl emulsifiable concentrate is harmful to the environment and the production investment cost is high, the present invention provides a kind of clodinafop-propargyl aqueous emulsion and its preparation method, the clodinafop-aparyl a...
