Alachlor is an odorless, white solid. The greatest use of alachlor is as a herbicide for control of annual grasses and broadleaf weeds in crops, primarily on corn, sorghum and soybeans. It has been the second most frequently used herbicide in Wisconsin. Only atrazine has been used more. A metabolite of alachlor, ethane sulfonic acid (ESA), is formed in soil and is subject to leaching. On the basis of the presence of ESA in monitoring wells downgradient of alachlor treated fields, DATCP and other state agencies decided that ESA should be included in the survey of alachlor in groundwater.

Alachlor is a selective systemic herbicide, absorbed by germinating shoots and by roots, for annual broadleaf control in crops such as beans, beets, cabbage, corn, cotton, ornamentals, peanuts, peas, potatoes, sorghum, soybeans, sugarcane, sunflowers, and tobacco. Selective systemic herbicide for control of most annual grasses and many broad leaved weeds in maize, sorghum, groundnuts, soya beans, lima beans, oilseed rape, brassicas, radish, oil radish, cotton, sunflowers, sugar cane, potatoes, peas, tobacco, some ornamentals. The compound works by interfering with a plants ability to produce (synthesize) protein and by interfering with root elongation .
