This product is used for warm season turf but what happens if I used it in Pennsylvania to cold season turf? Less effective but still works?
Surflan Pro Herbicide will harm cool season turf per the label; it could potentially damage these grasses or prevent them from growing. We would recommend using Prodiamine 65 WDG. It is a very good pre-emergent product that is safe for use on all established turf types. Also, please check out our Cool Season Lawn Schedule for information on when to use products.
