Embodiment 1

[0040] The 5% clodinafop-propargyl wettable powder product obtained in Example 1 has good dispersibility, and the effective suspension rate of clodinafop-propargyl has reached 90.1%. This medicament is applied to the wheat field to prevent and control annual grass weeds, and the dosage of active ingredients is 45-45%. 67.5 g / ha, 40 days after application, the overall plant control effect on grass weeds is 84.6%-91.5%, and the fresh weight control effect is 85.0%-92.9%, which is safe to wheat.

Embodiment 2

[0041] The 15% clodinafop-propargyl wettable powder product obtained in Example 2 has good dispersibility, and the effective suspension rate of clodinafop-propargyl has reached 88.7%. The agent is applied to prevent and control annual grass weeds in wheat fields, the dosage of active ingredients is 45-67.5 g / ha, and 40 days after application, the overall plant control effect on grass weeds is 86.1%-92.2%. The efficacy is 87.3% to 95.5%, which is safe to wheat.

Embodiment 3

[0042] The 8% clodinafop-propargyl wettable powder product obtained in Example 3 had good dispersibility, and the effective suspension rate of clodinafop-propargyl reached 88.3%. The agent is applied to prevent and control annual grass weeds in wheat fields, the dosage of active ingredients is 45-67.5 g / ha, and 40 days after application, the overall plant control effect on grass weeds is 84.8%-90.7%. The efficacy is 86.5% to 93.1%, which is safe to wheat.

Abstract

The invention discloses clodinafop-propargyl wettable powder and a preparation method thereof. The clodinafop-propargyl wettable powder is prepared from, by weight, 5%-20% of clodinafop-propargyl, 1.25%-5% of a safener, 1%-15% of solvent, 1%-8% of an emulsifier, 1%-15% of a wetting dispersant, 1%-25% of a synergist and the balance stuffing, wherein the total content of all the components is 100%. Due to the fact that the safener and the synergist are added, the safety of clodinafop-propargyl to wheat is improved, and the preventing and weeding effects of clodinafop-propargyl on annual gramineous weeds in a wheat field are also improved. The preparation method comprises the steps that clodinafop-propargyl, the safener, the emulsifier and the solvent are uniformly mixed to prepare an oil base; the oil base is uniformly sprayed on a dry base which is prepared from the stuffing, the wetting dispersant and the synergist and processed through air jet pulverization through a sprayer, uniform mixing, detecting and subpackaging are performed, and then the finished product is obtained. According to the clodinafop-propargyl wettable powder and the preparation method thereof, the problem that clodinafop-propargyl is melted in heat to be agglomerated during air jet pulverization is solved, and the effective suspension rate and the utilization rate of clodinafop-propargyl are increased.

Description

technical field [0001] The invention relates to the field of agricultural herbicide wettable powder, in particular to a clodinafop-propargyl wettable powder and a preparation method thereof. Background technique [0002] Clodinafop-propargyl (clodinafop-propargyl) is a phenoxycarboxylic acid chiral fluorine-containing high-efficiency and low-toxicity herbicide developed by Syngenta Crop Protection Co., Ltd. of Switzerland. Its mechanism of action is to inhibit acetyl-CoA carboxylase (ACC) in plants activity, thereby affecting the synthesis of fatty acids, which are necessary for the formation of cell membranes. [0003] Clodinafop-propargyl has a low melting point of 48.2-57.1°C; it has high solubility in organic solvents (25°C), such as acetone>500g / L, methanol>180g / L, toluene>500g / L, etc. [0004] Clodinafop-propargyl is an efficient and stable herbicide for post-emergence stem and leaf treatment of gramineous weeds in wheat fields. It is considered by some count...
