5.4 gr/acre (13.3 g/ha). 1 soluble bag treats 1 hectare or 2.5 acres.
Minimum 15 gal/ac (150 L/ha). Do not use liquid fertilizer as a carrier for Peak 75WG herbicide applications. Liquid fertilizer may prevent the water-soluble bags from dissolving properly.
For broadleaf weed control, Peak 75WG herbicide MUST be used only in tank mix with one of the following herbicides:
Field corn - Banvel® II herbicide or Banvel® Dry EG herbicide
Seed corn - Banvel® II herbicide
Winter wheat - Pardner® herbicide
Peak can also be tank mixed with glyphosate in glyphosate-tolerant field corn (as permitted by the PMRA tank mix policy of unlabelled tank mixes).
Field Corn: Apply Peak 75WG herbicide as a broadcast spray, with Banvel® II herbicide or Banvel Dry EG herbicide and a recommended surfactant, to field corn between the two and seven leaf stages.
Seed Corn: Apply Peak 75WG herbicide as a broadcast spray, with Banvel® II herbicide and a recommended surfactant, to seed corn between the two and seven leaf stages.
Winter Wheat: Apply Peak 75WG herbicide as a broadcast spray, with Pardner® herbicide and a recommended surfactant, to wheat up to and including BBCH Growth Stage 32 (beginning of stem elongation).
For optimum results, apply to actively growing weeds when they are in the one to six leaf stage.
Please refer to the label for detailed application instructions.

Do not use Crop Oil Concentrate if tank mixing with all Ultim® herbicide formulations or Accent® herbicide.
Ensure that the sprayer is totally clean.
Fill the spray tank three quarters full with water. Engage gentle agitation.
NOTE: Growers using a sprayer with by-pass agitation should allow the water-soluble bags to completely dissolve before engaging the by-pass. Otherwise, undissolved bags could be sucked into the by-pass and plug the main screen.
Ensure the agitation system is working properly and that it creates a rippling or rolling action on the water surface.
Add the appropriate number of water-soluble bags of Peak 75WG herbicide and Ultim® herbicide or Accent® herbicide, if being used, directly into the spray tank. Do not touch water-soluble bags with wet gloves. Allow eight (8) minutes for complete mixing. The water-soluble bag may become brittle with age and exposure to cold temperatures. Longer mixing time may be required if the bag is brittle or if the water is cold.
Ensure Peak 75WG herbicide and Ultim® herbicide or Accent® herbicide, if being used, is completely in suspension before adding the desired broadleaf weed tank-mix partner. Agitate an additional 2 to 3 minutes, then add a recommended non-ionic surfactant at 0.2% v/v (2.0 L for each 1000 L of water) or crop oil concentrate at 1.0% v/v (10 L for each 1000 L of water).
Do not use a crop oil concentrate if tank mixing with all Ultim® herbicide formulations, Accent® herbicide or Pardner® herbicide.
Continue agitation while completing the filling of the sprayer.
Continuous agitation is required to keep Peak 75WG herbicide in suspension. Do not allow the spray mixture to stand without agitation.
Use the spray suspension as soon as it is prepared.
Water soluble bags must be dissolved in clean water. After spraying a tank load, some of the mixture will remain in the bottom of the tank. For repeat tank loads, pre-slurry Peak 75WG herbicide in 10 litres of clean water (in a pail) prior to adding to the spray tank.
Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.
Effects of Weather
Do not apply Peak to winter wheat if cold, wet environmental conditions that stress wheat are expected within 1 week after application. Cold, wet weather following Peak applications to winter wheat may result in injury to the cereal crop; this injury is normally temporary and yields are not affected.
Under unfavourable environmental conditions such as drought, heat, flooding, prolonged cool temperatures or insufficient fertility, adequate control may not be achieved and re-growth may occur.
For maximum crop safety, do not apply Peak 75WG herbicide to corn which has been treated with an organophosphorus insecticide, such as Counter® (PCP 15268). If an IR corn hybrid is planted, organophosphorus insecticides can be used according to label directions without increasing the likelihood of injury to those hybrids when Peak 75WG herbicide is applied.
