ERDC/EL TN-11-3 "Evaluation of Commercially Available Herbicide Mixes for Control of Rosette Stage Yellow Starthistle (Centaurea solstitialis L.)"

چکیده
PURPOSE: Yellow starthistle is one of most problematic invasive species in grass and rangelands in the western United States. It has expanded its distribution since the 1950’s threatening native species’ diversity and reducing the utility of rangelands for livestock. Control of yellow starthistle has relied heavily on the use of picloram and clopyralid. Although these herbicides have been widely used and provide excellent control both pre-and post-emergence, new herbicide options need to be identified for rotation in herbicide stewardship programs. This study evaluated commercially available herbicide mixes as well as some herbicides that typically are not used in management programs to control mature plants just prior to the bolting growth stage.

Release of Roadside Native Perennial Grasses following Removal of Yellow Starthistle
The ecological benefits of a roadside native perennial grass stand are :ompromised when invasive species become estab· lished. We evaluated the potential to regenerate existing native perennial grass stand5 populat~d with yellow starthistle (Centaurea solstitialis) on a roadside planting in the lowland hills of t1e interior Coast Range of northern California. The experiment was designed to dete...

A Structural Growth Model of the Invasive Weed Species Yellow Starthistle, Centaurea solstitialis L
Yellow starthistle (Centaurea solstitialis L.) is a summer-flowering annual plant of the family Asteraceae, and a significant weed of roadsides, pasture and grasslands in California. It is also distributed, though with less economic and ecological significance, throughout the US and in other temperate parts of the world. Yellow starthistle grows vigorously during the dormant period for most nat...

The noxious weed yellow starthistle (Centaurea solstitialis L.) can be controlled effectively at the seedling stage with foliar application of the auxinic herbicides picloram or clopyralid. Although resistance to these herbicides is rare, a yellow starthistle biotype resistant to picloram and cross-resistant to clopyralid was observed in 1989 near Dayton, WA, in a pasture that had been subjecte...
متن کاملEstimating Yellow Starthistle (Centaurea solstitialis) Leaf Area Index and Aboveground Biomass with the Use of Hyperspectral Data
Hyperspectral remote-sensed data were obtained via a Compact Airborne Spectrographic Imager-II (CASI-II) and used to estimate leaf-area index (LAI) and aboveground biomass of a highly invasive weed species, yellow starthistle (YST). In parallel, 34 ground-based field plots were used to measure aboveground biomass and LAI to develop and validate hyperspectral-based models for estimating these me...
