Ortho Weed-B-Gone. I've got a couple of acres so I bought this little handy dandy sprayer that I drag behind my tractor. It hooks up to the battery and has an electric pump. You've got to get'em early in the season when they're cranking and before the bastrds start spreading their demon seeds.

Weed and feed sucks. You have to put it down when the grass is wet so the granules will stick to the leaves of the broad leaf weeds. Plus, you ought to feed in the fall.
