Description
A chemical used to kill or inhibit the growth of plants, especially weeds. Historically, sea salts, waste manufacturing products, and oils were used as weed killers. In the late 19th century, additional materials such as Carbon disulfide, Borax, Pyridine, Mercurials, and Arsenic trioxide were used to target weeds. By 1945, synthetic organic herbicides were developed which required very low dosage treatments. Weed killers are categorized as preplant, preemergence, and postemergence. Examples include amitrole, Picloram, 2,4-D, DDT, Atrazine, Glyphosate, diquat, and paraquat. Many herbicides do not decompose and have created long-term hazards to the environment.
