Abstract

The invention relates to a special herbicide formula for a corn field, belonging to the technical field of pesticide processing. The special herbicide formula comprises the following components in parts by weight: 1-5 parts of alachlor, 0.05-0.5 part of chlorimuron-ethyl, 0.1-5 parts of butachlor, 2-3 parts of pendimethalin and 100-200 parts of deionized water. The special herbicide formula for the corn field has the advantages of low cost, wide herbicide controlling spectrum, quick acting, high efficiency and no residue or harm, and has a good development and application prospect.

Description

technical field [0001] The invention relates to a special herbicide formula for corn fields, which belongs to the technical field of pesticide processing. Background technique [0002] Herbicides are agents that can completely or selectively kill weeds. Sodium chlorate, borax, arsenic acid, trichloroacetic acid have a deadly effect on any kind of vegetation, but because of their residual effects, they should not be used in the field. Selective herbicides, especially derivatives of nitrophenols, chlorophenols, and carbamic acids, are mostly 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 become the mainstream. [0003] Chemical herbicides developed rapidly in the 1950s due to their rapid action and ease of use. However, with the wide application of chemical herbicid...
