Herbicide used before seeding

Abstract

The invention discloses an herbicide used before seeding. The herbicide containing the following components in percentage by weight: 1%-5% of 2,4-D-dimethylamine salt, 2%-8% of 2,4-D-ethyl acetate, 5%-10% of acetochlor, 2%-10% of ammonium sulfate, 20%-30% of bentazone, 5%-10% of 3,6-dichloroanisic acid, 5%-10% of chloridazon, 1%-2% of clomazone, 2%-5% of potassium dichloropyridine, 2%-5% of dicamba, 2%-5% of dichloromide, 2%-10% of dimethylphenyl thioxamide, 2%-5% of fluoroglycofen, 2%-3% of glyphosate and 2%-5% of 2-methyl-4-chlorophenoxyacetic acid. The herbicide can be used for removing multiple types of weeds, is efficient, low in toxicity, low in residue and free of pollution, and weeds do not need to be removed again in the growth periods of plants.

Description

technical field [0001] The invention belongs to the field of herbicides, and more specifically relates to a herbicide used before sowing. Background technique [0002] Herbicides are non-selective or selective removal of weeds or specific weeds in the field to ensure the growth of plants and prevent weeds or specific weeds from absorbing nutrients in the soil, resulting in reduced plant production. As people have higher and higher requirements for the environment, higher requirements for planting efficiency, and more and more attention to food safety requirements, in recent years, the research and development direction of pesticides and herbicides is mainly reflected in high efficiency, low toxicity, low Residual and pollution-free. In the prior art, there are many types of pesticides, but most herbicides can only remove a few designated types of weeds. During the plant production cycle, specific weeding or manual weeding is required, and the work efficiency is low. , It co...

As people have higher and higher requirements for the environment, higher requirements for planting efficiency, and more and more attention to food safety requirements, in recent years, the research and development direction of pesticides and herbicides is mainly reflected in high efficiency, low toxicity, low Residual and pollution-free. In the prior art, there are many types of pesticides, but most herbicides can only remove a few designated types of weeds. During the plant production cycle, specific weeding or manual weeding is required, and the work efficiency is low. , It consumes a lot of manpower, which is not conducive to improving planting efficiency and reducing labor intensity
