When is the best time for me to apply one or more treatments of Tenacity for preemergent purposes? I am in the immediate Pittsburgh, PA area. Following treatments, I'll want to spot-seed the areas where the Tenacity blasted some annual grasses last summer and fall.
Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees.
It is recommended that you wait 2-4 weeks after an application of Tenacity Herbicide to reseed.
