View Full Version : Is this Dallis or Crab Grass? Need Help

What type of weed is this?

I need some recommedations on the procedure for getting rid of this type of weed? What do you think of Drive, Acclaim or Green Light MSMA Crabgrass killer. The latter says it takes care of Dallis and Crabgrass and can be ordered online?

Will any of this stuff yellow my lawn or kill it? I have read many people putting liquid iron in their mix.

Thanks alot of your help.

Doesn't look like crabgrass. This lawn is too thin. Is it a new lawn? Is there any chance it was started with a wheat straw mulch? Is it wheat?

This lawn is new over the past few years, new property. I dont think its wheat.

What kind of grass is that lawn? Dallisgrass grown in tight, short, wideleave clumps. Any chance of a closer photo? Looks close to orchardgrass.http://www.agry.purdue.edu/ext/forages/publications/grasses/orchardgrass.htm

can you get a picture of the seed head?

Its a fescue, rye mix...Scotts Premium Blend. I am in PA by the way. Someone in another forum said it might be Johnson grass, it looks more like this than Orchardgrass.

does not look like dallis grass at all, a pic of a seed head would help

looks like Timothy or Johnson Grass, from the growth that can be seen. A closer pic might be able to distiguish better. By the way, NICE PATIO too, lol.

Orchard grass??

Sure does not look like crabgrass to me but I can't help you on what it is.

Is that Italian Rye? Better for making hay than on a lawn. I've seen it pretty often in Scotts and other junk seed mixes for quick germination. It usually craps out on it's own come summer.

Looks like annual rye, common on new construction. Does it have clasping auricles? It'll die out on it's own eventually.

I see Dallisgrass on a daily basis here, so it definitely is not that.

Could be Poa Trivialis.

In another thread I already told you that Dalis grass doesn't grow in PA.


It's looking more like rough-stalk bluegrass to me (Poa Trivialis). But it could be any number of undesirable perennial weed grasses.

Roundup & start over.

Man Scott's Premium blend huh? Looks like when I put down contractors mix to get grass up quickly. Look at all the clover too. Premium it is not.

Dallisgrass, or paspalum, definitely grows in southeast Pa. You won't see it until mid summer usually. Two apps of msma spaced 3 weeks apart cleans it up nicely, as well as any crab or nutsedge thats in the lawn.

Will MSMA hurt my good or young grass? I have read it turns it yellow?

Thanks for your help.

MSMA can injure turf. I spray it with 90 to 120 gallons of H2O per acre, along with iron to minimize yellowing, and a good surfactant like LI700. What you are seeing is not dallisgrass, and msma will not kill it.

I found out this is wheat. My house was built on a very farm 2 arce horse farm. How do you get rid of wheat? and keep it gone?

Best way to get rid of wheat ( if it is wheat, looks like grain rye grass to me) is to keep it mowed so it doesnt produce seeds and it will probably die by the middle of next month on it own. Same cure for annual rye.
