Dinoseb is an organic solid -- yellowish crystals with a pungent odor. Its greatest use is as a contact herbicide for post-emergence weed control in cereals, undersown cereals, seedling lucerne and peas. Dinoseb is also used as a corn enhancer and an insecticide and miticide. The major source of dinoseb in drinking water is runoff from herbicide used on soybeans and vegetables.
Some people who drink water containing dinoseb well in excess of the maximum contaminant level (MCL) for many years could experience reproductive difficulties.
