  • Mixing Instructions
    1. Fill clean tank about 1/4 full with fresh water.
    2. Turn on full agitation.
    3. Add the proper amount of Accent 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 Accent 75 DF Herbicide has been well mixed and is in suspension add the proper amount of tank mix partner (if applicable) to the spray tank with the agitator running.
    5. After all products have been well mixed and are in suspension, add a recommended adjuvant (see “Spray Adjuvants” section for a complete list and use rate).
    6. If applicable, add 28% liquid urea ammonium nitrate (UAN).
    7. 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.
    Agitation is required for uniform mixing and application. The optimum water volume for Accent 75 DF Herbicide application is 140-190 litres of water per hectare (minimum of 100 litres of water per hectare).
    Use a spray pressure of 175 - 275 kPa. Flat fan nozzles are recommended. Use 50 mesh filter screens or larger. Use spray preparation of Accent 75 DF Herbicide within 24 Hours or product degradation may occur resulting in a loss of weed control. Use vigorous agitation to thoroughly disperse spray mixtures that have been allowed to stand in the tank.
