StriCore Herbicide

Turf Program Recommendations

Successful Pre-Emergent Programs

  • For effective & long-lasting weed control, overlapping residual herbicides are essential.
  • Well-timed pre-emergent applications will significantly reduce the need for post-emergent treatments.
  • Use diverse modes of action to minimize the potential for herbicide resistance.
  • For season-long goosegrass control, apply pre-emergent treatments every 45 - 60 days.
  • Consider tank-mixing StriCore® with other pre-emergent herbicides to extend the duration of control
