which product for Japanese stilt grass

Japanese stiltgrass is 1/2 of a sprawling lawn of 1 acre. What product to use without killing the lawn? Anyone.

Acclaim Extra works well for me, but it's getting pretty late in the season for full effectiveness. I've heard that Ornamec works, but I haven't tried it since the Acclaim Extra has worked. Don't forget to add a surfactant. I use MSO.

You should also put down a pre-emergent (Barricade).

Im not allowing it to seed. The tops get mowed off once a week. Is it still too late? Im understanding the Acclaim will kill the lawn too.

I have a little of this in a little piece of lawn I have (near a creek). If what I'm reading is correct, I don't see a post-emergent (selective) that will work and not kill cool season grasses. It's possible the site I got my info. from doesn't have knowledge of all postM's. Conceded.

If you have any bermuda, the ornamec will kill that, too.

Interested to hear what others have to say.

Acclaim Extra does not kill cool season grasses. It has worked on my lawn of fescue and KBG.

Heres my stiltgrass or crabgrass

I was told by Lawn Doctor that this is a type of early crabgrass. He insisted upon it and he is the only one who says this. Who do I listen too. He also said that Acclaim will brown everything up. He uses it but would not in my case. I dont know what to do.

joelcoqui - That's japanese stiltgrass. 100% guaranteed. Most of the big LCO guys will tell you there's nothing you can do if you get it in your lawn. Lawn Doctor in my town said, "Use Roundup and then re-seed." That's BS. Acclaim Extra will kill japanese stiltgrass and will NOT kill normal cool-season grasses. It's a tough weed and you need to keep up with it year after year, though. I'll try to post a picture of my dying stiltgrass when I get home. Just read the Acclaim Extra label... Lastly, I emailed Dr. Dernoeden at the University of Maryland and he confirmed that japanese stiltgrass can be controlled by Acclaim Extra. You need to use a fan spray nozzle (mist) and you need good soil moisture. Also, use Barricade as a pre-M next spring.

Here's another thread on this site about stiltgrass.

Good Luck!
