Kudzu: Where did it come from? And how can we stop it?
Kudzu is spreading in the South and control measures are required on large acreages. Control can be accomplished by persistent applications of effective herbicides or by overgrazing for two to three years. Soil-active herbicides containing the active ingredient picloram or dicamba are presently most effective. Herbicide sprays should be applied in a mixture with 60 to 100 gallons of water per acre; complete coverage is best achieved with double application and right-angle spray passes when using ground equipment. Repeated applications are usually required to kill every root crown. The tender nature of kudzu leaves and the large tuber roots make kudzu difficult to control.
