Answer: Vigoro Ultra Turf Weed & Feed for Bahia & Mixed Lawns contains the broadleaf weed control 2,4-D. It is not a pre emergent but a post emergent weed control product. If you received lots of rain after the application, I suspect the 2,4-D was rinsed away. Check the label for recommendations about reapplication. I'm sure there's a waiting period. Good luck with your lawn!
