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 Gateway™ 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 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 controls weeds and root systems that are present at time of application; weeds that have not emerged will not have the same level of control.
    • 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.
