Impede is a selective herbicide for postemergent control of annual and perennial broadleaved weeds in spring wheat, durum wheat, and spring barley.

DIRECTIONS FOR USE
Application Rate: 1.1 L/ha
Field sprayer application
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification. Boom height must be 60 cm or less above the crop or ground.
Best results are obtained when Impede is applied to actively growing weeds in the seedling stage and when Canada thistle is between 10 cm and up to but not including the early bud stage. Poor weed control may result under cool or dry conditions.

Spring Wheat, Durum Wheat and Spring Barley
Apply to the crop from 3 leaf to just before flag leaf. Apply Impede as a ground treatment using enough spray volume to provide adequate spray coverage. Apply a minimum of 100 L/ha total spray volume by ground. Higher spray volumes will provide better coverage and weed control, particularly when the weeds are not actively growing. Maximum 1 application per year.

Spray Preparation
1. Fill sprayer tank 1/2 full of water.
2. Start sprayer tank agitation.
3. Add the required amount of Impede and continue to agitate.
4. Add the required amount of tank-mix partner, if needed.
5. Fill the sprayer tank with sufficient water to spray 100 L of spray mixture per hectare.
Note: Add only the adjuvant on the tank-partner label and follow tank-mix partner label for order of mixing.

The use of flood jet or hollow cone nozzles is not recommended because of uneven and inadequate spray coverage. Ensure thorough and uniform spray coverage over the entire leaf area of the target weeds.
