Weeds - Leafy Spurge

Photo: Leafy SpurgeLeafy Spurge is a perennial with flowers borne in an umbel and are surrounded by yellowish-green bracts. These bracts turn yellow in late May, making them easier to identify. The plant has an extensive root system.

Leafy Spurge can reduce the cattle carrying capacity of rangelands by 50 to 75 percent. Once it is established, it requires an extensive program to eradicate.

Research at North Dakota State University shows a cost-effective option is a combination of picloram (Tordon 22K) and 2,4-D. In sensitive areas, use dicamba (Banvel) or glyphosate (Roundup). In all cases, repeat applications on an annual or semi-annual basis for three to five years. Always read and follow the label.
