Tenacity Herbicide can be used as a pre-emergent or a post-emergent. A post-emergent application on Tenacity Herbicide would be to kill weeds that are already there.

It is recommended that you water the product in 1/2 inch after application to get the product into the soil.
Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications.

It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.
