Important Information


    Pasture Guard MCPB is very effective on an wide range of broadleaf weeds in new pasture, allowing the pasture to establish in the paddock. It is one of the few options for cereal weed control when undersown with clovers or ryegrass / clover mixes.

    At all times you should refer to the Pasture Guard MCPB label. Rates vary from weed species and whether the plant is a seedling or established plant.


    Susceptible plants convert MCPB to MCPA. MCPA then accumulates in the growing points of stems and roots where it interferes with cell division and enlargement. Plants such as clover and peas do not convert to MCPA and are therefore not affected.


    • Keep out of reach of children.
    • Store in accordance with NZS 8409 Management of Agrichemicals.
    • Store in original container tightly closed in a locked, dry, cool, well ventilated area away from foodstuffs, fertilizers and seeds
