Embodiment 1

[0064] 3 parts of alachlor, 2.5 parts of metolachlor, 5 parts of promethazine, 4 parts of pendimethalin, 8 parts of methachlor, 11 parts of imazethapyr, 12 parts of fomesafen and 45 parts of carrier and surface Active agent 8 parts.

Embodiment 2

[0066] 4 parts of alachlor, 2 parts of metolachlor, 4 parts of promethazine, 5 parts of pendimethalin, 7 parts of methachlor, 10 parts of imazethapyr, 8 parts of fomesafen and 55 parts of carrier and surface Active agent 7 parts.

Embodiment 3

[0068] 2.5 parts of alachlor, 3 parts of metolachlor, 2~5 parts of promethazine, 5 parts of pendimethalin, 5~8 parts of pendimethalin, 8~11 parts of imazethapyr, 5~ of fomesafen 10 parts and 28~52 parts of carrier and 8 parts of surfactant. The herbicide formed by the above components is configured into a water dispersant, sprayed in a soybean field at 3.5% by weight of the original drug, and sprayed 1 hectare of soybean field with 50kg of the herbicide dispersant. The weed removal rate is 99%, and the weeds die naturally after one week, and have no effect on the subsequent soybean growth.

Abstract

The invention discloses a weeding composition, and particularly relates to a herbicide suitable for soybeans, and belongs to the technical field of herbicides. The weeding composition comprises the components in parts by weight: 0.5-5 parts of alachlor, 0.3-5 parts of metolachlor, 1-8 parts of prometryn, 2-7 parts of pendimethalin, 3-11 parts of MCPA, 5-14 parts of imazethapyr, 3-15 parts of fomesafen, 20-60 parts of a carrier and 7-10 parts of a surfactant. The weeding composition disclosed by the invention is specifically used for various weeds in soybeans, has a good removal effect and is short in residual life.

Description

technical field [0001] The invention discloses a herbicide composition, in particular relates to a herbicide suitable for soybeans, 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, and are a class of substances used to eliminate 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 t...
