Embodiment 1

[0028] Preparation of 26% glufosinate · beta-haloxyfop (1:1.6) microemulsion

[0029] In this example, the mass ratio of glufosinate and haloxyfop-methyl is 1:1.6.

[0030] The following components were weighed according to the proportion: 10kg glufosinate, 16kg high-efficiency haloxyfop, 10.0kg cyclohexanone (solvent), 10.0kg propylene glycol methyl ether (solvent), 12.0kg fatty alcohol polyoxyethylene ether (No. One surfactant), 5.0kg ethylene glycol (antifreeze), 14.0kg ammonium dodecylbenzenesulfonate (second surfactant), 23kg water.

[0031] Glufosinate-ammonium was dissolved in water to obtain an aqueous phase mixture. Mix the remaining components and stir evenly to obtain an oil phase mixture. Mix the water phase mixture and the oil phase mixture, and stir evenly to obtain the product, which is a homogeneous transparent liquid.

Embodiment 2

[0033] Preparation of 23% glufosinate · beta-haloxyfop (45:1) microemulsion

[0034] In the present embodiment, the mass ratio of glufosinate and haloxyfop-methyl is 45:1.

[0035] Weigh the following components according to the proportion: 22.5kg glufosinate, 0.5kg high-efficiency flurifop-pyl, 3.0kg cyclohexanone (solvent), 5.0kg isopropanol (co-solvent), 10.0kg fatty alcohol polyoxyethylene ether (first surfactant), 5.0kg ethylene glycol (antifreeze), 10.0kg ammonium dodecylbenzenesulfonate (second surfactant), 44kg water.

[0036] Glufosinate-ammonium was dissolved in water to obtain an aqueous phase mixture. Mix the remaining components and stir evenly to obtain an oil phase mixture. Mix the water phase mixture and the oil phase mixture, and stir evenly to obtain the product, which is a homogeneous transparent liquid.

Embodiment 3

[0038] Preparation of 12% glufosinate · beta-haloxyfop (1:3) microemulsion

[0039] In this embodiment, the mass ratio of glufosinate and haloxyfop-methyl is 1:3.

[0040]Weigh the following components according to the ratio: 3kg glufosinate, 9kg high-efficiency haloxyfop, 15.0kg C9 (solvent, C9 is trimethylbenzene), 8.0kg propylene glycol methyl ether (solvent), 15.0kg nonylphenol polyoxyethylene Ether (first surfactant), 5.0kg propylene glycol (antifreeze), 16.0kg calcium dodecylbenzenesulfonate (second surfactant), 29kg water.

[0041] Glufosinate-ammonium was dissolved in water to obtain an aqueous phase mixture. Mix the remaining components and stir evenly to obtain an oil phase mixture. Mix the water phase mixture and the oil phase mixture, and stir evenly to obtain the product, which is a homogeneous transparent liquid.

Abstract

The invention discloses a weeding composition with glufosinate and efficient haloxyfop methyl, and a preparation method of the weeding composition, and belongs to the agricultural field and aim to solve the problems that glufosinate has a poor prevention effect on perennial resistant plants, limitation of prevention and movement for perennial weeds, low weeding effect and high cost with exclusive use because of long-term massive use. The dosage form of the weeding composition is microemulsion and comprises glufosinate and efficient haloxyfop methyl. The ratio by weight of the glufosinate to efficient haloxyfop methyl is 1:5 to 45:1. The weeding composition prepared by the method has the characteristics of wide weeding range, high weeding effect and low cost. The pesticide effect is obviously better than any one of the glufosinate and the efficient haloxyfop methyl. The preparation method is simple and convenient to operate, and has the advantages of high feasibility, stable product quality and obvious market value. The composition still has good stability after being stored for a long time, thereby having obvious market values and being suitable for extensive generalization and use.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to herbicides, in particular to a herbicidal composition containing glufosinate-ammonium and high-efficiency haloxyfop-pyl and a preparation method thereof. Background technique [0002] Glufosinate-ammonium, also known as glufosinate, is a new phosphoric acid herbicide and a glutamine synthesis inhibitor. Its chemical structure is as follows: [0003] [0004] As a non-selective broad-spectrum contact herbicide with partial systemic action, it is mainly used to control annual and perennial dicotyledonous and gramineous weeds in orchards, vineyards, non-arable land, potato fields, etc. Oatmeal, crabgrass, barnyardgrass, wild barley, ryegrass multiflora, foxtail, golden foxtail, wild wheat, wild corn, creeping wheatgrass, grapevine bentgrass, whiskgrass, sedge, bermudagrass, two tassels Barnyardgrass, awn grass, fescue, reed, bluegrass, amaranthus, field chamomile, agarina, shepherd's ...
