Small diameter woody brush on forestlands and rights-of-way can be controlled with a basal bark application of either triclopyr or imazapyr. The purpose of this study is to evaluate the efficacy of triclopyr and imazapyr tank mixtures for a variety of rates and species. Imazapyr at the standard rate of 19 g ae/l does not have the broad-spectrum control of triclopyr at the standard rate of 96 g ae/l. Test mixtures adding various rates of imazapyr to the standard rate of triclopyr provided no significant benefit. This study documents effective basal spray treatments for 15 of 16 test species. Only eastern redcedar proved difficult to control.
