Arlyn....I think Grass Be Gone, Over The Top , and Post are similar products put out by different companies. How long ago did you spray? My sprayed grass actually looks greener but I'm confidant the GBG will work. I'm lazy and used a pre-mixed pump bottle. If it doesn't show results in a couple of weeks I'll get another bottle and respray. Did the OTT have a petroleum like smell. Keep us informed.
