Once mesquite encroachment is initiated it is difficult to reverse and continually degrades grasslands, hindering grass production that benefits both livestock and wildlife.

We evaluated the effectiveness of Sendero herbicide in the treatment of western honey mesquite.

We compared two treatment types (Sendero and Sendero plus Remedy Ultra) and two application methods (individual plant treatment and aerial broadcast).

Percent cover of grasses and some forbs increased throughout our study sites post treatment.

All treatment types were successful at decreasing the percent canopy cover of western honey mesquite, and we found no difference between treatment types.
