Smooth crab grass? Leaves are tender and velvety. Pulls up by these fragile, stringy pieces. I can never find a root/base. Intertwined in St. Aug.

Sure looks like crabgrass

Looks like Dallisgrass to me (but it may be Crabgrass too). You can tell by the slim stalk with the black seeds on it. It's a PITA to get rid of. I put a glove on and rub straight 41% glyphosate on the blades to kill the patch because my grass is St. Augustine. When you mow it, the seeds fly and new Dallisgrass pops up in other areas. Need to eradicate all of it or it will keep popping up.

Googling Dallisgrass it just looks so much like a head of normal crabgrass. This stuff is low profile. Grown horizontal along the st. Aug. Not up & out. You have to hunt to find it.

Outstanding id. That is smooth crabgrass.

Thanks! Celsius, roundup, napalm?

Le bump.

Unfortunately for St Aug, the best herbicides Available that kill crabgrass aren’t really compatible (To my knowledge). Image and Atrazine are some of the better options that are available but it’s getting too hot to use them. The best thing will be to put down a good pre-emergent this fall and then again in the late winter to prevent it from showing up in the first place. As far as this year, feel free to pull it or roundup it

Celsius will supress it and so will Blindside. Tenacity will kill it but you're only supposed to use Tenacity on sod farms. I'm only assuming because it will turn the grass white. You can use Tenacity on other residential lawns but just not st aug residential lawns.

Ok. Thanks guys. I'll used Celsius to knock it down for the year and then pre-emerg. it this fall and late winter. I've got a Celsius battle coming up for the spurge, VBW, and now this & a sedgehammer battle for the green kyllinga.
This stuff ONLY grows in the bottom left corner of my front yard. Nowhere else. It comes back in the same spot every year. I even put down pre-emerg from Fertilome that was supposed to handle it. Guess I was too late.

That green kyllinga is hard to get rid of. Seems like my first pass with sledgehammer didn’t do anything.

If you have celsius use that with sedgehammer.

You're such a boss. Can we seriously get Ronk and CrawDude some beers somehow? They have been super helpful to everyone. I bet they're so tired of answering the same ole shite.
Posted on 5/21/20 at 8:55 am to TheWiz
I love it and I know Craw does too. Sometimes I just feel repetitive in my answers but it doesn't bother me if it doesn't bother yall.
Posted on 5/24/20 at 6:36 am to ronk
Wow! Y'all weren't kidding. 3/4tsp to 1gallon pump sprayer and I ran out of weeds to spray in the front and back yard. This Celsius will last me an eternity.

It’s less expensive over time than many other “cheaper” herbicides for this reason.
On the crabgrass, obviously you are limited to post-emergent treatment b/c of the St Augustine, live with it this year, and focus on the late winter application (early Feb if in southern LA if we have another warm winter) of pre-emergent. Seeds germinate at soil temps of 55 F. Three years ago, prior to my using pre-emergents, I had a serious issue with crabgrass in an area of the lawn - I estimate the first year of using pre-emergent I eliminated 80-90% of the crabgrass, now - I can’t find a crabgrass plant in the lawn.

Have i been torpedoed by my new silt, or is this something i can selectively treat?

Sorry to hear that. What type of lawn grass?
Centipede - Sethoxydim
Bermudagrass/Zoysia - Quinchlorac
St Augustine - ?????

If the area isn’t sodded yet I suppose repeated applications of glyphosate.

Honestly I don’t what people can do now days in south LA with regards to river silt fill. Used to be you just had to avoid buying it from areas known to be contaminated with torpedograss, but based solely from posts on this board that doesn’t seem to the case anymore.
I’ll buy only mason sand now for filling low spots in the yard to avoid torpedograss but I really don’t know what people can do that need large amounts of fill material for a lawn if you live in many areas of south Louisiana.
