A herbicide is a type of substance that can completely or selectively kill weeds, used to eliminate or inhibit plant growth.

Sodium chlorate, borax, arsenate, and trichloroacetic acid have a withering effect on any type of plant, which is influenced by three factors: herbicides, plants, and environmental conditions. According to their effects, herbicides can be divided into bactericidal and selective herbicides. Selective herbicides, especially derivatives of nitrophenol, chlorophenol, and formic acid, are mostly effective. The development of herbicides in the world is gradually stabilizing, mainly developing high-efficiency, low toxicity, broad-spectrum, and low dosage varieties. Disposable treatment agents with minimal environmental pollution are gradually becoming mainstream.

The commonly used varieties are organic compounds, which can be widely used to control harmful plants such as weeds, miscellaneous irrigation, and miscellaneous trees in farmland, orchards, flower nurseries, grasslands and non cultivated land, railway lines, rivers, reservoirs, warehouses, etc.
