Options for glyphosate-resistant (GR) Palmer amaranth [Amaranthus palmeri (S. Wats)] control are becoming limited. Research was conducted in 2014 and 2015 to evaluate the effectiveness of rescue herbicide applications on glyphosate-resistant Palmer amaranth. Research was established to evaluate efficacy provided by new and current herbicide programs on GR Palmer amaranth that was larger than recommended at the time of herbicide application. Studies included a postemergence application of different herbicides used singly and in combination at different initial application timings; sequential postemergence application timing evaluating herbicide tank mix combinations at five different time intervals between applications; and postemergence evaluation of herbicide tank mix combinations at multiple application timings.
