GENERAL INSTRUCTIONS

FREQUENCY Herbicide is a post-emergence, contact foliar-absorbed herbicide and will not control weeds which emerge after application. FREQUENCY Herbicide will provide rapid bleaching of the target weeds. When mixed with bromoxynil according to the label, this additional activity will lead to rapid burning of target weeds. Both FREQUENCY Herbicide and bromoxynil are light activated herbicides. Faster and more complete activity will be seen in higher light conditions. Due to the contact nature of FREQUENCY Herbicide applications early in the season where better coverage is possible will result in better control. In some instances, complete control of weeds may not be seen; however, a significant reduction in biomass will be observed and weeds will likely be uncompetitive with the crop.

To ensure thorough weed coverage, FREQUENCY Herbicide should be applied in a minimum of 80L/ha water. Refer below to APPLICATION section for further details.

MIXING

Invert drums and shake well prior to commencing mixing. Half fill the spray tank with clean water. Commence agitation and add the required amount of product to the tank. Maintain agitation whilst filling the tank and throughout the spraying operation.

FREQUENCY Herbicide is a suspo-emulsion formulation. When using in a tank mix with other herbicides, the following mix order should be observed:

  1. Half fill the spray tank;

  2. Add any granule (WG) formulated products first and allow dispersion, followed by any suspension concentrates (SC/flowable);

  3. Add any water-soluble salts;

  4. Add FREQUENCY Herbicide and any EC formulations;

  5. Add any adjuvants as recommended.

Adjuvants

FREQUENCY Herbicide requires the use of an MSO type adjuvant such as Hasten to allow better uptake into the target weed for full efficacy. Use of non-ionic surfactants and mineral oil-based adjuvants will likely result in reduced efficacy.

APPLICATION

Ground application: Apply in 80-150 L of water per hectare using a nozzle that will deliver a MEDIUM spray quality. The use of flat fan, air induction nozzles is recommended. In advanced or dense weed infestations, or dense crop canopies and if tank mixing more than 2 listed products, increase the water volume to ensure adequate coverage.
