Thorough, more-complete control

Plants absorb Surmount® herbicide through roots, foliage and stems for greater uptake that provides lasting results.

Excellent weed control without 2,4-D

Surmount is an outstanding option for areas where 2,4-D use is restricted or where a non-2,4-D option is desired. Preemergence and soil residual activity controls weeds that emerge after application.

Safe to desirable grasses

Surmount is tough on broadleaf weeds, yet gentle on most forage grasses.
