Dave the 24d products all work well on what you are targeting post emergence, spray before seeding at a young stage for best control. There are really good 24d products out there that are broad spectrum as well and have long residuals which will only have the need to spray once a year (Grazon is one) but may not be available in your area without licensing. Pre-emergence products are a good choice too and can go down to prevent the unwanted seed from sprouting. Atrazine is a good one. Get a handle on it for a couple of years and you may be able to skip a couple of seasons. Good luck...
