Simazine 4L is a preemergence herbicide only for preventing weeds emerging from seed when applied before they germinate. It does not control anything actively growing and is not labeled for bentgrass control. Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/Fall applications will be more effective than Spring applications. If you are able to spot treat with RoundUp QuikPro, that is another option. 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.
