Product Q&A

Answer:

Tenacity Herbicide is not labeled to control orchardgrass. Unfortunately, we do not know of any selective herbicide that will kill orchardgrass without harming your desirable turfgrass.  It is usually recommended to spot treat the orchard grass as much as possible with a non-selective product like RoundUp QuikPro, and then replant in those areas in a couple of weeks when the orchard grass is gone.
