Product Q&A

Answer:

Nufarm Weedar 64 is not labeled for use on St. Augustine grass or for residential lawns.  You may be able to use a product like Hi-Yield 2, 4-D Selective Weed Killer instead.  It is a selective, post-emergent herbicide which controls dozens of broadleaf weeds and is safe to use on St. Augustine grass.
