Important Information


    A high concentrate, selective herbicide for the control of grass weeds in certain broadleaf crops, forestry, orchards, white clover and non-crop areas.

    Ideal in tree release and can be used as part of a tank mix with other commonly used herbicides for this purpose.

    Use with Collaborate Spray Oil for improved performance.

    Valiant® 520 will control annual grasses such as Poa annua and a range of perennial grasses such as couch, cocksfoot, paspalum and perennial ryegrass.​

    Please note: treated crops or residues should not be grazed. 


    Valiant® 520 may be applied using conventional ground or aerial equipment. If mixing with other chemicals they should be added before Valiant®520. It is always best to refer to the product label for application rates and details.

    Haloxyfop, the active ingredient in Valiant 520, does not have any grazing withholding period established in New Zealand for forage crops. Ravensdown does not recommend any use of Valiant 520 on forage crops.

    Mix required quantity in spray tank partly filled with water and maintain agitation through filling and spraying. When appropriate, spray oil such as Collaborate should be added once Valiant® 520 has been thoroughly mixed. When tank mixing with a compatible herbicide these should be thoroughly mixed and dispersed before Valiant® 520 is added to the tank.

    Valiant® 520 may be used in mixture with AtrafloSimafloTerbaflo and Multiple.

    WARNING: If broadleaf herbicides, particularly sulfonyl ureas, have been used at any time prior to applying Valiant® 520, ensure the spraying system has been thoroughly decontaminated in accordance with the relevant herbicide label directions prior to using the equipment to apply Valiant® 520. This is necessary to avoid the risk of crop damage from chemical residues that may be present in the spraying equipment from previous applications.
