Rattail Fescue Management in Winter Wheat Grant uri icon



  • Rattail fescue is difficult to control in direct-seed winter wheat cropping systems with current management tactics, which rely almost exclusively on herbicides (Ball et al 2007, Jemmett et al 2008). Over the past several years, populations of rattail fescue have increased in direct-seed dry land winter wheat production systems in the Palouse region of the PNW. It is not a new weed species in the region; however its incidence is expanding rapidly in circumstances where soil disturbance is minimized in direct- seed systems. Integrated management options for effective rattail fescue control in winter wheat cropping systems have not been adequately investigated and need to be developed. The proposed research will provide Palouse region winter wheat growers with up-to-date, cost-effective, management practices for rattail fescue populations in direct-seed dry land winter wheat cropping systems. Palouse region winter wheat growers will have effective management tools for rattail fescue, which will allow continued use of conservation tillage systems. This will improve farm sustainability, reduce soil erosion, and improve water quality.
