Abstract

The invention relates to the field of agricultural technology, and provides a safe herbicide and a preparation method thereof. The safe herbicide is composed of a herbicide active drug, a synergist, a safener, a surfactant and water, wherein the herbicide original 10-35% of drug, 2-5% of synergist, 3-8% of safener, 2-5% of auxiliary agent, 2-8% of surfactant, and the rest is water; wherein, the safener is phenylsulfone Acylurea substances; the herbicide active drug is selected from at least two of the following components: acetochlor, alachlor, butachlor, atrazine, 2,4-D butyl ester, metolachlor . The herbicide of the invention is safe, stable, reliable, low in cost and good in weeding effect.

Description

technical field [0001] The invention relates to the technical field of agricultural reagents, in particular to a safe herbicide and a preparation method thereof. Background technique [0002] Herbicide refers to a class of substances that can completely or selectively kill weeds, and are used to eliminate or inhibit plant growth. The development of herbicides has gradually stabilized, 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. Herbicides are divided into killing and selective herbicides according to their functions. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. Selective herbicides: Herbicides have different degrees of resistance to different types of seedlings. This agent can kill weeds but is harmless to seedlings. Selective herbicides ca...
