	Banvel/Clarity or Direx(Preplant)	Cotoran or Reflex + Prowl	Glyphosate + Staple + Dual Magnum (Dual should be applied 5 days or more before or after the glyphosate + Staple.)	Valor † + MSMA
	Treflan or Prowl PPI	Cotoran or Reflex + Staple	Glyphosate + Dual Magnum (if seedlings have not emerged.)	Valor + MSMA
Liberty Link	Valor or Reflex(Preplant)	Prowl + Staple or Direx	Liberty 280 +Dual Magnum (Liberty will control emerged seedlings)	Direx + MSMA
