The Butachlor Amides Herbicide

Product Description:

Butachlor is an amide-based, conductive, selective pre-emergence herbicide, also known as noralachlor, machete, and alachlor. This product is a light yellow oily liquid with a slight aromatic odor. It is not easily soluble in water and easily soluble in various organic solvents. It has chemical stability under normal temperature, neutral and weak alkaline conditions. Its decomposition is accelerated under strong acid conditions and can be degraded in soil. Low toxicity to humans and animals, irritating to skin and eyes, and high toxicity to fish. It is mainly absorbed by the shoots of the weeds, followed by the roots. After plants absorb butachlor, it inhibits and destroys proteases in the body, affects the formation of proteins, and inhibits the normal growth and development of weed shoots and roots, resulting in the death of weeds.
