Life cycle of Puccinia acroptili on Rhaponticum (= Acroptilon) repens.
Russian knapweed (Rhaponticum repens) is a rangeland weed pest in the western United States. One candidate fungus for biological control of R. repens is Puccinia acroptili, which causes a rust disease. Understanding the life cycle of candidate rust fungi for weed biological control is an essential component in risk assessments and evaluations, and for P. acroptili such was unknown. For this rea...
متن کاملCercosporella acroptili and Cercosporella centaureicola sp. nov.--potential biological control agents of Russian knapweed and yellow starthistle, respectively.
Russian knapweed (Acroptilon repens [L.] DC.) and yellow starthistle (Centaurea solstitialis L.) are invasive weeds in the western United States, and both weeds are targeted for biological control. Cercosporella acroptili (Bremer) U. Braun was identified as a possible biological control agent for A. repens, and a morphologically similar Cercosporella sp. recently was found damaging to C. solsti...
متن کاملTransportable arrays in Wyoming, Colorado, and New Mexico
Introduction. Ps and Sp images of sub-moho negative arrivals beneath the intermountain region of western U.S. are made using dense (2-40 km station spacing) arrays shown to the left that recorded for 1-2 years: the CREST, RISTRA, SIEDCAR, LODORE, LARAMIE, BILLINGS array data combined with Transportable Array data. The nominal Sp interpretational zoo includes an LAB arrival thought to manifest t...

متن کاملRevegetating Russian Knapweed (Acroptilon repens) and Green Rabbitbrush (Ericameria teretifolia) Infested Rangeland in a Single Entry
The objective of this study was to test the potential for using a single-entry procedure to revegetate Russian knapweed– and green rabbitbrush–infested rangeland. I hypothesized that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. For Russian knapweed, treatments included three seeding rates (zero, low, and high...
