How long after application is Tenacity rainfast?
Applied 4oz/acre to 30 day old seedlings and got 1.5" of rain a few hours later. Rainfall was quick enough to cause flooding, 1.5" in about 2 hours. Will the Tenacity application be effective?
Tenacity Herbicide will be rainfast 4 hours after it has been applied or after it has dried.
