Integrated Management of Leafy Spurge - W866
Leafy spurge is the most difficult noxious weed to control in North Dakota and infests all 53 counties in a variety of environments. Leafy spurge is found in pasture, rangeland, cropland, roadsides, shelterbelts, and other non-cultivated areas. Cultivation will control leafy spurge in conventional cropland, but the weed can become the dominant species in reduced-till cropland, pas-ture, and rangeland if not controlled.

Leafy Spurge Control Using Flea Beetles - W1183
Leafy spurge is an exotic perennial weed that infests over 800,000 acres in North Dakota. Although leafy spurge can be successfully controlled with herbicides, treating large acreages is not cost-effective. In fact, approximately 40 percent of the leafy spurge infested rangeland has a carrying capacity below the herbicide cost break-even point. Using biological agents to control leafy spurge has become an economic alternative in many locations in the state.

Leafy Spurge Identification and Chemical Control - W765
Leafy spurge (Euphorbia esula L.) is a widely established perennial weed in North Dakota, infesting approximately 990,000 acres of land in 2005 (North Dakota Department of Agriculture survey). The leafy spurge infestation in North Dakota seems to have peaked at about 1.5 million acres in 2000 and 2001. The decline thereafter has been a result of an effective control program initiated in the early 1980s. Prior to this control program, leafy spurge acreage doubled every 10 years from 1950 to 1985. Despite the decline in acreage, the widespread infestation continues to cost the state more than $75 million annually in lost production.

This publication is designed to help land managers identify the state- or county-listed noxious weeds. Other species included are those with the most potential to spread within the state or into North Dakota from bordering states.
