Important Information


    Highly visual spray marker dye.

    Visible for up to 10 days post application.

    Assist Red Dye allows the spray operator to identify sprayed plants and areas for up to 10 days following application. This saves re-treatment, chemical wastage and labour. While spraying it shows the operator exactly what coverage they have on the target plant.


    Assist Red Dye can be used through most types of application equipment such as knapsacks, spot spraying systems including motorbike units and hand guns.

    Recommended use is at 100-200mL per 100 litres or 10-20mL per 10 litre knapsack. The actual rate of use depends on the visual response wanted by the operator. Consult the product label for more accurate rate required based on the target species.


    4 x 5L packs per outer (box).


    • 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

    Add Assist Red Dye to water in the spray tank first, agitate or mix thoroughly before adding any other product.

    Under most circumstances Assist Red Dye is compatible with most pesticides including phenoxy based products and brush weed herbicides.

    Several factors can affect this compatibility and therefore it is recommended to do a jar test prior to using products with alkaline chemistry such as Pasture Guard MCPA and Pasture Guard MCPB.
