Embodiment 1

[0045] 2 parts of glyphosate, 2 parts of giazolin, 2 parts of 2,4-D butyl ester, 6 parts of trifluralin, 35 parts of carrier and 5 parts of surfactant.

Embodiment 2

[0047] 3.5 parts of glyphosate, 4 parts of glyphosate, 2 parts of 2,4-D butyl ester, 10 parts of trifluralin, 70 parts of carrier and 12 parts of surfactant.

Embodiment 3

[0049] 2.5 parts of glyphosate, 5 parts of glyphosate, 2 parts of 2,4-D butyl ester, 10 parts of trifluralin, 65 parts of carrier and 11 parts of surfactant.

[0050] The herbicide prepared by using the above examples is suitable for weeds in rapeseed, and the weed removal rate is as high as 95%. Finally, the herbicide can be rapidly degraded in the soil, and the residual effect period is 7 days.

Abstract

The invention discloses a weeding composition. The weeding composition is prepared from the ingredients in parts by weight: 1-5 parts of glyphosate, 1-7 parts of haloxyfop-R-methyl, 0.5-3 parts of 2,4-D butyl ester, 2-12 parts of trifluralin, 30-70 parts of carrier and 5-17 parts of surfactant. The weeding composition disclosed by the invention is low in dosage and low in cost, has a good control effect on Gramineae weed, broad-leaved weed and sedge, is short in residual period and can be rapidly degraded in soil, and the residual period is 10-15 days.

Description

technical field [0001] The invention discloses a herbicide composition and belongs to the technical field of herbicides. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to destroy or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants, and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage, and disposable treatment agents with little environmental pollution have gradually beco...
