Beckie, H.J.Legere, A.Thomas, A.G.Juras, L.T.Devine, M.D.2018-09-092018-09-091998-02-19http://hdl.handle.net/10388/10131A survey conducted in 1996 indicated that one in nine fields has Group 1-resistant (R) wild oat and one in twenty fields has Group 1 -R green foxtail in Saskatchewan. However in the Parkland region, one in six fields has R wild oat and one in eleven fields has R green foxtail. One in five Group 1-R wild oat populations exhibits Group-2 resistance; these multiple-R populations greatly restrict chemical control options for producers. Results from this survey should alert producers to be more proactive in preventing, delaying or managing R weeds, by practicing herbicide-group rotation and integrated weed management.enAttribution-NonCommercial-NoDerivs 2.5 CanadaPresentation
