Revegetating 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...
متن کاملRestoring Species Richness and Diversity in a Russian Knapweed (Acroptilon repens)–Infested Riparian Plant Community Using Herbicides
Species richness and diversity are important indicators of ecosystem function and may be related to plant community resistance to invasion by nonindigenous species. Our specific objective was to determine the influence of clopyralid plus 2,4-D, glyphosate, and fosamine, at different application rates and timings, on richness and diversity of total species, total native species, and total nonnat...
متن کاملHost Range of, and Plant Reaction to, Subanguina picridis.
The host range of the knapweed nematode, Subanguina picridis (Kirjanova) Brzeski, under controlled environmental conditions was extended to include, in addition to Russian knapweed, Acroptilon repens (L.) DC., plant species within the Centaureinae, and Carduinae subtribes of the Cynareae tribe of the Asteraceae family. Examination of host response to nematode infection revealed that Russian kna...
متن کاملstudy of different techniques for breaking dormancy and optimum temperature for germination of russian knapweed (acroptilon repens)
abstract increased knowledge of russian knapweed biology would facilitate development of an optimum control program. to examine germination characteristic of this weed, several experiments were conducted in weed research department, plant pest and diseases research institute of tehran during 2003. first experiment was a factorial with 3 replications to break seed dormancy of this weed. first fa...
متن کاملBiology of Subanguina picridis, a Potential Biological Control Agent of Russian Knapweed.
The knapweed nematode, Subanguina picridis, forms galls on the leaves, stems, and root collar of Russian knapweed, Acroptilon repens. After being revived from a dormant, cryptobiotic state, second-stage juveniles required at least 1 month in a free-living state before becoming infective. Galls were induced on relatively slow-growing host plants that retained their apical meristems at or near th...
