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 کاملIntegrated Management of Leafy Spurge-Infested Rangeland
Leafy spurge is an invasive Eurasian weed on pastures and rangeland in North America where it reduces grass forage production. Our objective was to determine the effects of multispecies grazing combined with Aphthona flea beetles on leafy spurge-infested rangeland. On two westernNorth Dakota sitesdivided into four25to79-hapastures, two grazingduration treatmentswere applied: season-long with 7 ...
متن کاملOverwintering survival of Aphthona beetles (Coleoptera: Chrysomelidae): a biological control agent of leafy spurge released in North Dakota.
We evaluated the effects of snow cover and debris cover on overwintering success of Aphthona from 2001 to 2004 in southeast North Dakota. Chill degree-days, soil temperature, and duration of soil temperatures were monitored in field plots. Emergence of Aphthona from soil cores collected in October and held in the laboratory under simulated winter conditions did not differ across treatments. Fie...
متن کاملDetection of Flowering Leafy Spurge With Satellite Multispectral Imagery
The distribution and abundance of flowering leafy spurge (Euphorbia esula L.) can be determined with hyperspectral remote sensing, but the availability of hyperspectral sensors is limited. Hence, the Landsat 7 Enhanced Thematic Mapper Plus (ETMþ) and System Pour d’Observation de la Terre (SPOT) 4 imagery were acquired to test the ability of these sensors to detect leafy spurge. The green:red ba...
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...
