Technical Presentation, 65th Annual Meeting and Trade Show of the Society for Range Management, Spokane, Wash.

Enhanced livestock grazing and wildlife habitat

Sendero offers best-in-class grass safety and has minimal impact on desirable forbs and certain wildlife browse species. Sendero controls mesquite but leaves behind guayacan, pricklypear, tasajillo, cenizo, torrey croton, leatherstem, coyotillo, oreganillo, riogrande beebrush and elbowbush. Sendero causes short-term canopy reduction on guajillo and kidneywood.

Timing is Key for Controlling Mequite

 

Sendero herbicide has proven to be more consistent and more efficacious than a mixture of Remedy® Ultra and Reclaim® herbicides.1 But even with this effective tool for mesquite control, land managers and applicators still need to make applications at the right times.

To control mesquite with Sendero, or any herbicide, soil temperature should be at least 75 F. Avoid treating in low humidity, during drought stress or after a big rain following a dry period. Avoid spraying during active bean elongation of mesquite trees.
