  • Application Method

    Aerial: Apply Reclaim II Herbicide at the recommended rates in a minimum spray volume of 30 L/ha by air. For better coverage use 50 L/ha.

  • Approved Use
    Refer to the Reclaim II label for complete use instructions.
    Refer to the Controlled Weeds list for the full list of weeds.
  • Rates

    • One case treats 20 acres.
    • Apply a minimum of 20 gallons of water per acre by ground.
    • Apply a minimum of 5 gallons of water per acre by air.
    • Reclaim II requires the addition of a non-ionic surfactant such as Gateway™ adjuvant at 0.25% v/v for ground application or 1% v/v for aerial application.

  • Application Timing

    • Target timing to the most problematic plants. For example, if your primary target is buckbrush, timing will likely be earlier (June 1 to July 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.
    • Reclaim II 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.

    Removal of competing vegetation may result in new Canada thistle shoots emerging.

  • Mixing Instructions

    Mixing with Water
    1) Fill the spray tank 3/4 full of clean water.
    2) Add the required amount of Reclaim II A Herbicide with the agitation running. Pre-slurrying with water may be necessary where there is little or no agitation or an injection system is being used or where herbicide is first added to a tank other than the spray tank.
    3) Add the required amount of Reclaim II B Herbicide with the agitation running.
    4) Add the recommended surfactant (such as Gateway Adjuvant, AG-SURF, AGRAL 90 or CITOWETT PLUS) at 0.25% v/v or 2.5 litres per 1000 litres of spray solution.
    5) Add antifoaming agent, if required.
