Soilborne microorganisms of Euphorbia are potential biological control agents of the invasive weed leafy spurge
Leafy spurge (Euphorbia esula-virgata), a native of Eurasia, is a serious invasive weed of grasslands of the northern Great Plains of the U.S. and prairie provinces of Canada. Leafy spurge is very difficult to control with herbicides, insect biological control agents, and other cultural practices. Previous field investigations revealed pathogen–insect interactions on the roots of leafy spurge l...
متن کاملComparison of methods for selecting fungi pathogenic to leafy spurge
Studies were conducted to compare six inoculation methods for preliminary screening of potential fungal biocontrol agents for leafy spurge (Euphorbia esula). The six inoculation methods included 1) applying spore suspensions to surface-disinfested, detached leaves of leafy spurge in petri dishes; 2) applying spore suspensions to untreated, detached leaves of leafy spurge in petri dishes; 3) app...
متن کاملShort-term Disruption of a Leafy Spurge (Euphorbia esula) Biocontrol Program Following Herbicide Application
Integrated pest management (IPM) for invasive plant species is being advocated by researchers and implemented by land managers, but few studies have evaluated the success of IPM programs in natural areas. We assessed the relative effects of components of an IPM program for leafy spurge (Euphorbia esula), an invasive plant, at Theodore Roosevelt National Park, North Dakota. Effects of herbicides...
متن کاملTraining lambs to be weed eaters: Studies with leafy spurge
The objective of the study was to determine if exposure of young lambs to leafy spurge (Euphorbia e&u L.) would increase the consumption of this plant. Orphan lambs were exposed to leafy spurge from birth to 11 weeks of age as a water soluble extract mixed with milk replacer and as freshly harvested plants. Ewereared lambs were exposed to leafy spurge by grazing them on a leafy spurge-infested ...
متن کاملLong-Term Dynamics of Leafy Spurge (Euphorbia esula) and its Biocontrol Agent, Flea Beetles in the Genus Aphthona
Three flea beetle species (Aphthona spp.), first introduced into North America in 1988, have come to be regarded as effective biological control organisms for leafy spurge (Euphorbia esula). The black flea beetles (Aphthona lacertosa and A. czwalinae) in particular have been shown to cause reductions in leafy spurge stem counts in the northern Great Plains, while the brown flea beetle (A. nigri...
