ASSESSMENT OF THE EXTENT AND SUCCESS OF LEAFY SPURGE BIOLOGICAL CONTROL AGENTS AgEcon
Hodur, Nancy M.; Leistritz, F. Larry; Bangsund, Dean A..
Leafy spurge is an exotic, noxious, perennial weed which is widely established in the north central United States and is an especially serious problem in the northern Great Plains. In 1997, the Agricultural Research Service and the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture (USDA), initiated a major Integrated Pest Management (IPM) research and demonstration project, TEAM Leafy Spurge (TLS), to develop and demonstrate ecologically based IPM strategies that can produce effective, affordable leafy spurge control. A key component of the project was to expand the use of biological control (biocontrol) agents, specifically flea beetles. To assess the level of insect establishment and the level of current and perceived...

PERCEPTIONS OF LEAFY SPURGE BY RANCH OPERATORS AND LOCAL DECISION MAKERS: AN UPDATE AgEcon
Sell, Randall S.; Bangsund, Dean A.; Leistritz, F. Larry.
A survey of 476 ranchers and 45 local decision makers (LDM) (521 total) was conducted to evaluate managerial, institutional, and social factors that may affect the rate and extent of implementation of various leafy spurge (Euphorbia esula L.) controls. The respondents represented a four-county region in Montana and North Dakota and are compared and contrasted to a group of ranchers and LDM from surrounding counties surveyed in 1998. The questionnaire focused on weed management in general and specifically on the perceptions and attitudes of ranchers and LDM who have been directly and indirectly affected by leafy spurge. Overall, the updated survey results reveal that ranchers and LDM had fewer problems with all noxious weeds, including leafy spurge than...
