Technical Specifications

  • Application Method
    • Ground or air; use coarse sprays to minimize drift.
    • Backpack applications to small areas: create a 0.67% solution of Grazon XC in water for weed and shrub control (e.g. mix 67 mL of Grazon XC in 10 L of water).
    • For all applications, coverage of the targeted foliage is very important.
  • Approved Use
    • Refer to the Grazon XC label for complete use instructions.
    • Refer to the Controlled Weeds and brush list for the full list.
  • Rates
    • 1.9 L/ac for broadleaf weed control.
    • 2.5 L/ac for tree.
    • Addition of a non-ionic surfactant such as Intake adjuvant is required to control certain tough to control weeds and trees. 
    • For rates specific to your desired result, please consult the label or call the Solutions Centre at 1-800-667-3852.
  • Application Timing
    • Target timing to the most problematic plants. For example,  if your primary target is absinthe wormwood, timing will likely be earlier (May 15 to June 15). If the primary target is Canada thistle, wait long enough for the majority of thistles to emerge (July 1 to 30).
    • Apply when the primary target plant is actively growing,  after emergence and prior to flowering.
    • Environmental stresses such as severe drought or extended periods of heat may decrease efficacy.
    • Grazon XC can only control weeds and root systems that   are treated; weeds that have not emerged will not have the same level of control as weeds that were fully emerged.
    • Initially, target plants will show limited visual activity following application; however, plant growth will stop. More effects can be observed 45 to 60 days following application.
    • Successful application provides at least two years of  improved grass production.
