Comparison of herbicide mixtures for exotic shrub suppression in wildland settings

Glyphosate-free herbicide combinations were compared to the standard glyphosate plus triclopyr against burning bush (Euonymus alata), privet (Ligustrum obtusifolium), Morrow's honeysuckle (Lonicera morrowii), autumn olive (Elaeagnus umbellata), and Japanese barberry (Berberis thunbergii). Combinations of triclopyr and aminopyralid plus metsulfuron or aminocyclopyrachlor plus metsulfuron provided control equal to the standard treatment for all species.
