Ted, this time of year is not too late to kill broadleaf alone and wait until next year. Here the KBG will fill in by fall as long as we don't dry out. Next year setting the deck higher stops those grasses for the most part. On big jobs, heck for me even smalll ones I can't sell Quinclorac this time of year. It's $50/lb(covers an acre) and that is out of the question for the folks I work for. I'm not making any customers promises of perfection at this point. They only see dandylions in the Spring. They are happy to wait as long as it is some shade of green they are happy. Bare dirt would upset them more it seems. OP? edit- this year we are still in the high 70s so I added some more N to accounts last week. That is crazy for this time of year here. We're only talking UAN32 at 2 gal/acre but it really worked nice with 45 gal of water/acre and some 2,4-d for some scragglers. The last 2 I did haven't got rain(it was in the forecast) and after a week they look better too. Nice and green. Great year here so far.
