Never, ever, ever use weed and feed or any preemergent mixed with fertilizer.
I use isoxaben (Gallery) and prodiamine (Barricade) in the fall and dithiopyr (Lesco) in the spring
You can just use prodiamine instead of dithipyr in the fall and spring; but dithiopyr is so widely available, it's easy to just drive to Lowes/HD and get a bag.

Feb 14th Valentine's day dithiopyr
