When I first moved into my condo with huge grounds, it was infested with weeds throughout, despite PAR III application twice a year. Eventually some board members prevailed in reducing the pesticide application to once a year and allowing concerned owners to opt out. The substantial, weed-free lawn adjacent to my house has not been sprayed in many years. Yet it is completely weed free, in contrast to the lawns that have been sprayed religiously until the fall of 2006, at which time the owners voted to cease spraying altogether. I have been pulling dandelions by hand on the entire condominium property with substantial success. Not much is being said about plantain, which seems to be more persistent and difficult to get rid of than dandelions are.
