  • Mixing Instructions
    When tank mixing Ultim™ 75 DF Herbicide with a broadleaf herbicide, always read the broadleaf herbicide label before using and follow all precautions.
    Always add components to the spray tank in the following order:
    a) dry formulations in water soluble packaging.
    b) other dry materials and finally c) liquid materials.
    1) Fill clean tank about 1/4 full with fresh water.
    2) Turn on full agitation.
    3) Add the proper amount of ULTIM 75 DF Herbicide to the water in the spray tank with the agitator running. Maintain full agitation until water soluble bags are completely dissolved and product is fully dispersed. Continuous agitation is required to keep the product in suspension.
    4) After ULTIM 75 DF Herbicide has been well mixed, add the proper amount (if applicable) of DISTINCT*, if applicable. Add slowly and agitate until completely dispersed.
    5) While the mixture is in suspension add the proper amount (if applicable) of BANVEL* Herbicide, BANVEL* II Herbicide, MARKSMAN Herbicide, PARDNER* Herbicide, CALLISTO* 480 SC Herbicide, or AATREX* Liquid 480, to the spray tank with the agitator running.
    6) After ULTIM 75 DF Herbicide (and tank mixed herbicide if applicable) have been well mixed and is (are) in suspension add a recommended non-ionic surfactant such as CITOWETT* PLUS, AGRAL* 90, or AG-SURF* at 2 L per 1000 L spray solution (0.2% v/v) or SIDEKICK* at 2.5 L per 1000 L spray solution (0.25% v/v).
    7) If the tank mix partner is DISTINCT* Herbicide add UAN at 12.5 L per 1000 L of water after the surfactant has been well mixed.
    8) Fill the remainder of the spray tank.
    On repeat tank loads, ensure that the amount of spray solution left in the tank from the previous load is less than 10% of the volume about to be mixed.
