Optimizing Performance

  • Apply to actively growing weeds and shrubs. Avoid applying to plants under stress.
  • For faster burndown of coniferous species, use Gateway adjuvant at 0.25% by volume (250 mL/100 L of water).For maximum rainfastness, increase the rate to 0.375% (375 mL/100 L of water). Gateway should be added after the herbicide is thoroughly mixed
  • Do not spray areas if injury to existing forage legumes cannot be tolerated.
  • Take appropriate measures to prevent application or drift onto plants and trees that are not intended for control.
