FORMULATION & ACTIVE INGREDIENT: PEAK is a water dispersible granule containing 750 g/kg prosulfuron.
TARGETS: Annual broad-leaved weeds in grain and forage maize.
TARGETS: Annual broad-leaved weeds in grain and forage maize.
RAINFASTNESS: 2 hours
RESTRICTIONS
Do not apply to forage maize and grain maize grown for seed production.
Only treat healthy maize, preferably in good growing conditions, when the vegetation is dry, and not during periods of high temperature.
PEAK is generally highly selective of maize. In exceptional situations (cold, heavy rain), use of PEAK can temporarily slow down growth.
Do not apply with organo-phosphate insecticides.
Do not use during periods of frosty weather, when frost is imminent, or onto crops under stress from frost, water logging, insect attack or drought.
Special care should be taken to avoid damage by drift to broad-leaved plants outside the target area or land intended for cropping e.g. beet, sunflower, oilseed rape, vegetable crops.
Ensure spraying equipment is thoroughly washed out according to specific instructions after use. Do not allow washings-out to drain onto land intended for cropping or growing crops.
WEEDS CONTROLLED
PEAK can be used to control the following weeds between 2-4 true leaf stage in maize. PEAK is a post-weed emergence herbicide. It is absorbed by the leaves and roots of the plant and blocks weed growth by inhibiting the synthesis of amino acids.

WEED RESISTANCE
Resistance Strategy
Do not rely on sulfonylurea herbicides as the sole means of weed control. The use of mixtures or sequences with other herbicides with different modes of action, active against the same target weeds, is desirable. This will minimise the possible development of resistant weeds.
Contact your distributor or Syngenta UK Limited for further information.
CROP SPECIFIC INFORMATION
Timing and Rates of Use
PEAK should be applied to the maize crop from the 2 leaf stage and no later than the 10 leaf stage.
To obtain the best efficacy, it is preferable to use PEAK at the 2-4 leaf stage of the weed targets.
PEAK is used at a rate of 0.02 kg/ha (20 grams/ha) with an approved non-ionic type adjuvant.

FOLLOWING CROPS AND RECULTIVATION
Recultivation
In the case of failure of a maize crop treated with PEAK, it is recommended to wait four weeks after treatment and to plough before re-sowing. Maize can then be re-sown.
ROTATIONAL CROPS
Autumn
Winter wheat, winter barley and winter beans can follow a forage maize and grain maize crop treated with PEAK provided the soil has been ploughed to a depth of 15 cm
Spring
Spring wheat, spring barley, spring peas and beans may be sown in the spring following application of PEAK, do not sow any other crop at this time.
MIXING AND SPRAYING
Spray Volume
Use a water volume of 150-300 litres per hectare.
Spray Nozzles
A medium spray quality is preferred for application of PEAK (see BCPC guidelines). A spray pressure of 2-3 bar is recommended.
Mixing and Spraying
Make sure the sprayer is set to give an even application at the correct volume.
