Important Information


    Long lasting residual herbicide with no knockdown of established weeds

    Has no effect on established plants

    Useful for amenity areas, tracks and situations where a long lasting residual herbicide is required

    Where possible and if the weed species are known it is always best to control them with products such as Simaflo before they get established or even germinate. Simaflo is a cost effective option for this purpose.​

    As the weed spectrum is immense and rates do vary according to specific situations it is always best to refer to the label.


    Simaflo has very little effect on existing vegetation and is absorbed through through the roots of seedling weeds as they germinate. It inhibits photosynthesis with symptoms of yellowing and then death. Whilst being a residual herbicide it is has very low water solubility and therefore does not leech as much and does not cause as much leachate damage as other similar triazine products.


    • 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.
