Crab grass

[vhdawg]

My yard at the house we've been in the last year has enough of it that it's a nuisance. I'm sure it's too late for this year, but how can I exterminate this stuff?

ETA: the predominant actual grass is centipede.

MSMA. Well depends on the type of grass you wish to have.

 

[DesotoCountyDawg]

If you can't find MSMA, find any kind of yard spray that has quinclorac in it.

We spray it on rice and it is absolute death on crab grass plus it doesn't discolor your yard.

Most people say pre-emergent really knocks out the crabgrass best. Problem for me is, I had fescue and due to its high maintenance, I'm often re-seeding it in the early fall and early spring (which is about the same time you're supposed to put down pre-emergent. So I never get to use it either.

I get decent results with the stuff you buy at Lowe's. If it's widespread, you might just be dealing with it for the rest of this year.

The MSMA will work on zoysia and bermuda, it hurts just about all other grasses around here.

It's a colloquial term coaches use to disparage and motivate young men who are more interested in horsing around with each other rather than the task at hand during practice.

Oh, crab grass. I misunderstood.***

MSMA will kill centipede grass, about your only option is 24D but start with a weak mixture and work up because too much 24D will kill centipede also.

Come on man, if you don't know what your talking about just don't type a response!!!
2,4-D will not repeat will not kill crab grass (read a label) 2,4-D will work on broad leaf weeds and not on grassy weeds. As mentioned in previous post Quincloroc will work on crab early, 2-3 three leaf stage. It will slow older crab but the plant will recover in a few weeks.
Your best defense is to pre-emerge, but that is past you now.

 

[DesotoCountyDawg]

If it's Bermudagrass you can spray a pretty heavy rate of Quinclorac and come back about 3 weeks later and hit it again.

 

[moturfdog]

Agreed
the sooner you spray the better also if you can stand it it will take out mature, seed head stage crab better than mid season, idk why maybe something to do with amount of carbohydrate reserves in the plant

 

[DesotoCountyDawg]

It functions the same as Johnsongrass. In the summer you can't completely kill Johnsongrass because you can't kill the rhizome but if you spray it in the fall with the seed head on it, it will be gone forever. It takes in the roundup all the way to the rhizome and kills it completely.

I realize it's too late for this year. What sort of pre-emerge should I use, and when?

 

[DesotoCountyDawg]

For your area I would probably do a preemerge in February (or whenever you see trees and bushes starting to bud). Something with pendimethalin in it is pretty good for crabgrass. I think Scotts has some different products you can buy in the store that have it.

I just put out Scott's summer(post emergent) weed and feed on my Bermuda. Great results after about 10 days. All of my broad leaf weeds were killed and I can see my bare spots are filling in. I would reccomend giving Scotts a try especially if you have a small yard.

Also so if your yard is nice and thick it helps choke out a lot of crab grass.

I know I'll get hammered for this but if you've got a small area that's really bothering you in particular....pull the **** up by the roots while it's wet like it is when you have a few minutes. You'll be surprised how much area you can cover in 4 or 5 15 minute sessions. The stuff is just hard to deal with period.

 

[DesotoCountyDawg]

I pull up Dallisgrass. It's just easier than trying to spray it.

 

[thekimmer]

Just get you a bunch of these.

 

[WilCoDawg]

Thanks!

I pull up Dallisgrass. It's just easier than trying to spray it.

I had to google that grass to see what it was. My yard was infested with it last summer almost overnight. I sprayed it with 3 weed spray applications to no avail. Then I spot treated w roundup which pretty much put a dent in it but it was still around. I gave up and sprayed my entire front due to that crap.

Marinate in Dales for 24 hours. Quickly sear and then put on the grill to lock-in flavor. Serve with mole crickets.

As DesotoCountyDawg said, use Quinclorac 75 DF on it this year. Will wipe out this year's crabgrass. Then, start spraying Prodiamine pre-emergent every early fall (to prevent winter and spring weeds) and early spring (to prevent summer invasive grasses and weeds) in subsequent years. It's generic Barricade. You don't have to use a surfactant with the Prodiamine, as it needs to get down in the soil. Make sure you apply it right before a rain, as it needs water to enter the soil to stop germination. The longer period of time between when you spray it and when it gets water, the less effective it will be. A jug of Prodiamine ( you can order it online at doyourown.com) for $63, but that jug will last you a long time.

I did that a good but this year and it has done wonders for my yard. It really is the easiest way to get rid of crab grass. I have a small lot though. It only works for small areas unless you acquire some serfs.

 

[thatsbaseball]

I started doing it because if you kill it and leave it in place your desirable turf struggles to fill in where the dead crab grass plant and roots remain. Crab grass is a ***** to deal with.

Keeping it in the same thread at

May I ask what this is...

Evidently it's a tough *** weed because it laughs at pre emergent and shrugs off everything you spray on it. The crap is all in my front yard too.

 

[ShrubDog]

You have a case of crabs

This is the seed head to what this thread is about. Crabgrass

Meh. If it's green mow it. Wise advice I got from an older gentleman many years ago. Now, I am an older gentleman and I pass it on.
