Billy from Broken Arrow Oklahoma writes

When is the best time of year to apply Tenacity Herbicide? In the Fall or in the Spring?

Answer:

Tenacity Herbicide can be used both in spring and fall for pre emergent control of weeds when soil temps are around 55 degrees. Tenacity is one of the top pre emergents for cool season turfgrasses in fall and can be applied at the same time as overseeding without inferferring with grass seed germiantion.  For post emergent control of actively growing weeds, a Non Ionic Surfactant is required to be added to tank mix. Post emergent applicaitons can be applied anytime the weeds are actively growing. Please refer to the list of Weeds Controlled on the product label for information on pre/post emergent control of targeted weeds.
