Can you identify this southern weed for me? I want to kill them without killing bermuda.?
http://i338.photobucket.com/albums/n440/bandoslav/... is a weed cluster that has started to spread out.
http://i338.photobucket.com/albums/n440/bandoslav/... is a weed plant that has not yet spread, but about to.
http://i338.photobucket.com/albums/n440/bandoslav/... is multiple weed clusters amongst bermuda. In the background is a border of these weeds.
http://i338.photobucket.com/albums/n440/bandoslav/... is a huge cluster of weeds let alone for a month, very tall (24") and I'm holding a seed cluster in front. They don't seed out until they are very large.
General characteristics: very dense & moisture retaining. Easily clogs mulching mowers. Very fast growing, on the order of 1/2" to 1" per day. Very tollerant of full sun to full shade, overpowers bermuda. Roots are a thin cluster.
Location: Tennessee & Mississippi.
What doesn't kill it: Ortho weed b gone, trimec w/MSMA, Scotts weed n feed, Bayer broadleaf weed killer.
I ran out of character space to finish...
What doesn't kill these: Image lawn weed killer, Tractor Supply brand broadleaf weed killer, MSMA from local co-op.
The only way I've found to kill these is to pull up manually by the root. Unless the soil is extremely moist (or unless there is a thick layer of mulch), the root ball will bust and the weed will regrow. Even roundup takes multiple applications to truely kill a plant.
How they spread: Mostly by extending a long leaf and sprouting a new plant where it touches the ground. Only neglected weeds left to grow to adulthood actually create seed stems.
The only weed I have found that can come close to competing with this weed's growth rate & spreading capacity is crabgrass...which is very easily controlled.
Growing season: all of them. Stays green year round, but does not spread as fast during the winter months.
On the lawn service...I've used & fired Trugreen -and- Scotts lawnservice for the sole purpose being their inability to control this weed.

Looks to me like its quack grass. The reason you broad leaf killers didn't work is because its not a broad leaf, its a type of grass. You might try something with crab grass killer. If that doesn't work then you have quack grass, and about the only way to get rid of that is to physically get rid of it. You might also want to take a sample to your local cooperative extension office and see what they say. Thats what they are there for. Good luck.

I'm not sure if you have TRUGREEN up there, but they are a lawn treatment service that comes around once or twice a month depending on your service selected. They will spray certain chemicals to kill weeds and put down fertilizer for the type of grass you have. The only downfall is they can be kind of expensive, but it's worth it.

Judging from the pic, it looks like either dallisgrass or goosegrass. Or, could be both. are you sure each pic is of the same type? You can kill dallisgrass using glyphosate. It may be necessary to have to apply it a couple times though.Goosegrass wil usually have a silver looking center. Glyphosate or something containing calcium acid methanearsonate will kill this weed. Go with the glyphosate and it will kill either types.
good luck

I totally empathize with you. I have the same weeds growing in my yard. But, mine is in the grass so it's really hard to distinguish the weed from the St. Augustine. I wish I could help you with the name of the weed. You could take one down to your garden store and they'll probably be able to tell you. Good luck!
