Embodiment 1

[0052] The present embodiment provides a kind of transgenic soybean field herbicide composition, and its dosage form is wettable powder, according to percentage by weight, described composition comprises: essence glufosinate-ammonium 10%, chlorimuron-methyl 35%, (((4- Phenyloxy)-3-methoxyphenyl)methylene)bis(4-chlorophenyl)dithioacetal 0.2%, fatty alcohol polyoxyethylene ether 3%, dodecyl naphthalene sulfonate 2 %, polycarboxylate dispersant 1%, PEO 10%, kaolin to make up to 100%.

[0053] This example also provides the preparation method of the herbicidal composition: Weigh the raw materials according to the weight percentage, add the raw materials into the coulter mixer, and mix them uniformly; then use the jet mill to pulverize until the particle size of the powder is less than 45 μm, that is, wettable powder.

Embodiment 2

[0055] The present embodiment provides a kind of transgenic soybean field herbicide composition, and its dosage form is water suspension concentrate, and according to percentage by weight, described composition comprises: essence glufosinate-ammonium 56%, chlorimuron-methyl 2%, (((4- Phenyloxy)-3-methoxyphenyl)methylene)bis(4-chlorophenyl)dithioacetal 10%, lignosulfonate 2%, polycarboxylate dispersant 1%, sulfuric acid Salt dispersant 2%, defoamer 0.3%, thickener 0.12%, antifreeze agent 4%, preservative 0.2%, PEO 10%, add water to make up to 100%.

[0056] This embodiment also provides the preparation method of the herbicidal composition: Weigh the raw materials according to the weight percentage, add the raw materials into the stirring tank and stir them fully, and shear at the same time during the stirring process; after stirring for 55 minutes for 30 minutes, pass the materials through the sand The mill is used for grinding so that the particle size D50 of the powder shall ...

Embodiment 3

[0058] This embodiment provides a kind of herbicide composition of transgenic corn field, its dosage form is water dispersible granule, according to percentage by weight, said composition comprises: 5% of refined glufosinate-ammonium, 3% of chlorimuron-methyl, brassin Lactone 5%, amine alkoxylate 0.5%, polyacrylate 0.5%, citric acid 0.3%, lactose 1%, AOT 10%, and the rest is diatomaceous earth.

[0059] This example also provides the preparation method of the herbicidal composition: Weigh the raw materials according to the weight percentage, add the raw materials into the coulter mixer, and mix them evenly; the mixture is pulverized into 800-1000 mesh fine powder by ultra-fine jet mill Add the aqueous solution of the obtained fine powder and binder (lactose) into a mixer and mix evenly, granulate with an extrusion granulator, and then dry at 50-100°C to obtain water-dispersible granules.

Abstract

The invention relates to the field of preparation methods of pesticides and herbicides, in particular to a refined glufosinate-ammonium herbicide. The herbicide comprises an active component A, an active component B, a crop physiological regulator, an anti-drift agent and other pesticide adjuvants, the active component A is refined glufosinate-ammonium; the anti-drift agent is one or more selected a high-molecular polymer PEO, an anionic surfactant AOT and diallyl polyether. The refined glufosinate-ammonium compound composition widens the weed control spectrum, enriches the use method, can be used for stem and leaf spraying and soil spraying, and can delay the resistance of weeds to refined glufosinate-ammonium; the composition can be applied to transgenic crop fields, the pesticide cost is reduced, and the safety risk of crops is reduced; and the anti-drifting assistant is added into the herbicide composition disclosed by the invention, so that the effects of reducing the specific gravity of fine fog drops and improving the drifting resistance of the fog drops can be achieved.

Description

technical field [0001] The invention relates to the field of preparation methods of pesticide herbicides, in particular to a refined glufosinate-ammonium herbicide. Background technique [0002] Glufosinate, the chemical name is 4-[hydroxyl (methyl)phosphono]-DL-homoalanine, and the molecular formula is C 5 h 15 N 2 o 4 P, belongs to phosphinic acid high-efficiency, low toxicity, partial systemic, non-conductive contact herbicide. Unlike glyphosate for root killing, glufosinate first kills leaves, and conducts transmission in plant xylem through plant transpiration. Inhibit the activity of glutamine synthetase in plants, cause nitrogen metabolism disorder in plants, excessive accumulation of ammonia, lead to the disintegration of chloroplasts, destroy photosynthesis, and eventually kill plants. Its quick-acting property is between paraquat and glyphosate, easy to degrade in soil, safe for crops, not easy to drift, wide herbicidal spectrum, high activity, less dosage, and...
