Monopoly Herbicide (MSMA) mode of Action:

  • MSMA is a foliar absorbed herbicide. It accumulates in root and leaf tips, where it rapidly kills leaf and stem tissue.
  • MSMA has multiple sites of action within the plant (Group Z herbicide), however it is thought to impact on weed growth by interfering with ATP production (energy storage) and cell division (growth process).
  • MSMA is typically more effective on grass weeds than broadleaf weeds. MSMA is generally rainfast within 3 hours of application and has partially systemic properties which allow it to move through the plant.
  • Susceptible weeds generally turn yellow to brown 3-7 days after  MSMA application.

Application Information:

  • Application rates are typically 6.6L/Ha in 400 – 1000 litres of water. Split applications of 3.3L/Ha in 400 – 1000 litres of water applied 7-10 days apart will reduce phytotoxicity. Weeds should be sprayed when they are young and actively growing. Repeat spray applications after 14 days may be necessary for difficult to control weeds.
  • MSMA products may cause some yellowing and discolouration of turf even when used as per label recommendations. High temperatures will increase this phytotoxic effect. Do not use on Bent, QLD Blue Couch, Fescue, Blue Grass, Kikuyu or Dichondra as damage may result.
  • With higher water volumes, the in-built surfactant within the formulation may be too diluted to gain optimal results. Hence, a non-ionic surfactant is recommended at the rate of 100 mL/100L of water.
  • Temperature plays a role in Monopoly performance. For best results, the application should be conducted when weather conditions are warm and dry, and when air temperatures are above 25°C. To limit phytotoxicity, the use of Monopoly should be restricted when temperatures exceed 35°C.

    Can I mix a MCPA chemical (Kamba M) with Monopoly, to control broadleaf weeds as well as burr grass in turf ?

    Asked by Mark on April 14, 2022 5:30 pm
    Answered by the admin

    Neither Monopoly nor Dicamba M state on the label that the other product is compatible in a tank mix.  As the product's label legally binds us, we can't recommend this tank mix be done.

    We often hear of 'off-label' tank mixes that combine broadleaf herbicides and MSMA; however, if you choose to do this, we recommend a jar test beforehand (mix the same chemicals/ratios in a small quantity) to test for antagonism. When tank-mixing different chemicals, do not add concentrate herbicides first.  Half fill the spray tank before the addition of any herbicide and agitate.
