Important Information


    Selective herbicide for the control of certain broadleaf weeds in all fodder brassica crops including bulb crops

    Cost effective option for controlling weeds in fodder brassicas

    Should be used with Collaborate Spray Oil for best results

    Purge is commonly used at very low rates (350mls/hectare) for post emergent broadleaf weed control in fodder brassicas in conjunction with a spraying oil such as Collaborate.

    Always refer to the label for application notes and use as directed.

    Always apply Purge to fodder brassicas in combination with Collaborate Spray Oil at 500 ml per 100 lt spray mix for aerial and ground spray use. For CDA applications use 500 ml per ha.


    Clopyalid and picloram are both absorbed by leaves, stems and roots; both then translocate through the plant, interfering with cell pision and stem elongation.


    4 x 5L packs per Outer (box).

    • Store in accordance with NZS 8409 Management of Agrichemicals.

    Half fill the spray tank and add the required amount of Purge. Add the remainder of the water, with the agitator running. If required add a spraying oil such as Collaborate. Maintain agitation during spraying. Only mix sufficient spray solution for immediate use and avoid storing.

    Purge is compatible with most other commonly used herbicides.
