re: Grass / Weed Identification thread and what kills it. (complete)

I know this is a random bump, but there is a lot of good info in this thread so I didn't want to start a new one.

I have a Bermuda grass lawn that was seeded back in April when we moved into our house. It took most of the summer to get a noticeable amount of Bermuda established. I have been fighting Dallisgrass most of the summer but it looks like I also have some Yellow nutsedge as well as some Virginia button weed that has exploded after the rains the past few weeks. Is there any single product that will take care of both the sedge, dallis and buttonweed but not totally burn out the Bermuda? I have read that Certainty works for the sedge and Celsius works for everything else, but that's over $200 worth of products.

I am trying to take advantage of the last two months of the growing period to try and establish as much grass as I can.
