Important Information


    ​Knockdown and residual non-selective herbicide

    Can be used pre-planting for forestry establishment or as a release treatment over newly planted trees

    Is used in some crops including lucerne, peas and maize to control certain grass and broadleaf weeds

    Terbaflo is the largest forestry release product sold in New Zealand because it can be applied over the top of seedling trees to control grasses and broadleaf weeds.
    In peas it is an extremely cost effective and easy chemical to use for controlling most common weeds.
    It is one of the few chemicals that can be used successfully for controlling clumpy grasses such as annual, perennial ryegrasses and cocksfoot in established lucerne crops.
    Terbaflo has a long half life, and is one of the mainstays in total vegetation control mixes.

    Application rates do vary from crop to crop so it is wise to read the label prior to use.


    Terbaflo is mainly root absorbed but some foliar uptake does occur. It is then translocated in the plant to inhibit photosynthesis at the growing point.


    • 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 area away from foodstuffs, fertilisers and seeds.
