Title: Evaluation of Sulfometuron for Leafy Spurge Control and Forage Production
Author: Lym, Rodney G.; Swenson, Orval R.
Description: Leafy Spurge is an aggressive and persistent perennial weed that takes over untilled, noncropland habitats such a pastures, rangeland, roadsides, wooded areas, and waste areas. Areas where cattle can graze can be reduced by 50 to 75%. Picloram (Tordon), a herbicide, can reduce leafy spurge by 90%. Piclorum is expensive and the long soil persistence of it's residue make it an undesirable solution. Sulfometuron(Oust), a sulfonylurea herbicide,is used to many weed control applications in noncropland areas. Several trials were conducted to determine it's overall effectiveness against leafy spurge. It was sprayed onto the selected areas. Sulfometuron is the first herbicide know to directly inhibit leafy spurge root bud formation. It alone or applied with an auxin herbicide tended to reduce overall forage production. It shouldn't be applied annually as it may damage grass.
