"Apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre at two to three week interval for up to three applications. Apply with a NIS surfactant. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications."

Tenacity Herbicide can be applied at the same time as seeding (unless grass is more than 20% stand of fine fescue). If application cannot be done within 7 days of seeding you would need to wait a minimum of 30 days, or until the seed has emerged and been mowed at least twice before applying to the lawn.
Morning dew will not lessen the effects of Tenacity. It some circumstances a more moist soil will make for better root uptake. You are safe to make the Tenacity application in the cooler times of the day when temps are below 85 degrees. If temps rise above 85 degrees after the product has dried it should not reduce effectiveness.
