Frequency®

Herbicide

Mode of action: Group 27 herbicide (formerly H)
Active ingredient(s): 60 g/L Topramezone 60 g/L Cloquintocet-mexyl 320 g/L Liquid hydrocarbons

 

Frequency® Herbicide adds new dimension to selective weed control as it's the first post-emergent Group 27 herbicide that isn't locked into partner chemistry. You can fine-tune the chemistry and rate of the tank-mix partner to find your perfect Frequency and maximise control of tough weeds.

Key benefits

  • Versatile new Group 27 chemistry
  • Freedom to choose the most appropriate second active
  • Excellent control of hard-to-manage broadleaf weeds
  • The flexibility to dial up tank-mix partners’ rates
  • Reduction of wild oats (Avena sterilis) seed-set in northern NSW & Qld
  • Very favourable plantbacks

How it works

  • Efficacy

    Frequency is a contact herbicide which provides excellent control of a wide range of broadleaf weeds, including hard to kill weeds such as fleabane. Target weeds will show symptoms in 3–7 days and will usually die in 14–21 days. BASF recommends applying Frequency with a tank-mix partner such as bromoxynil or MCPA, which can be ‘dialled up’ in the mix according to the size and spectrum of the target weeds. Choosing tank-mix partners from different MOA groups can also help overcome resistance issues.

  • Mode of action

    Frequency’s active ingredient, topramezone, has a Group 27 mode of action – it is an HPPD inhibitor (a “bleacher”).

  • Compatibility

    Frequency is physically compatible with Ally*, Associate*, Agritone* 750 and LVE, Axial*, Bromicide* 200, bromoxynil, Flight* EC, MCPA (LVE), metsulfuron, Jaguar*, Paragon* Xtra, Sencor* 480 SC, Tigrex* and Topik* 240 EC. Frequency is also physically compatible with Easy N* liquid fertiliser, but application of that mix may result in increased crop effect. Trials have shown mixtures with picolinofen or diflufenican can cause foliar burn without affecting crop yield.

  • Plantbacks

    Frequency has very favourable minimum plantback periods. Check the label of any product mixed with Frequency® Herbicide to determine any plant back periods or restrictions on use.
    6 weeks: wheat, barley, maize.
    4 months: canola, cotton, chickpeas, faba beans, field peas, lentils, lupins, mungbeans, safflower, sorghum, sunflowers.

  • Suppression

    Seed-set in wild oats in northern NSW and Queensland cropping zones where Avena sterilis is dominant in the targeted population.

  • Application method

    Ground application only.
    Use an appropriate tank-mix partner at a rate suited to the weed spectrum & size.
    Add Hasten at 1%.
    Ensure good coverage with medium spray quality using 80–150 L/ha water.
    Do not apply to stressed crops.
