Crab grass!

[Chas Hurst]

The crab grass slipped in on my lawn this spring. I have sprayed Ortho crab
grass killer on it with very dissapointing results. It was left over from
last year. Does it have a shelf life once opened? Are there other brands of
crab grass killer that work better?

Where do you live? It seems very early for crabgrass in most of the US.

To answer your question, there are a number of varieties of crabgrass
killer. The one I like is Image. I had a huge amount of crabgrass in my new
zoysia last summer. I sprayed it with Image in one of the hose end
applicators and the crabgrass was noticably damaged in a week or so and
completely gone in 3 weeks or so.

UC Davis has great info even if you're not in CA... most of the info
applies.

My experience is that crabgrass killers work very slowly. And, they
are weak. I need about 3 applications, 2 weeks apart. And even then,
it takes a few weeks for the crabgrass do whither.

I agree that it's too early for crabgrass for most of the US.
Crabgrass needs soil temps in the 70s to germinate, which is why it's
not a problem most places until 2-3 months from now.

If it is crabgrass, Aclaim is the best product I've found. It's not a
typical retail product that you'll find at home centers. You need to
buy it at an agri supply type place, like Lesco.

Same here, I've had the same experiences like that too. I was
told.... if it was stronger, the regular grass would die too.

I just get mad and pull the stuff up by hand now. If I'm in a rush, I
run around spraying, and come back later, since the crab grass
'yellows' so I can find it later when I have time.

later,

Thanks for all the replies. I live in SE PA and did not expect to see crab
grass this early, but there it is.

I kind of doubt it. Can you post a pic of it here?
