Unseasonably Warm Weather - Crabgrass Prevention?

DCTepper

Like many other areas we have had unseasonably warm weather for more than a week now (in the 80's when we should be in the 50's). I've received mixed advice on whether or not to apply the first treatment to my lawn (Scotts Turf Builder With Halts Crabgrass Preventer). The weather looks like its going to turn back to "normal" in the 50's-60's in the upcoming weeks, should I do this now or should I continue to wait?

I put pre-emergamt down in Jan. Personally, i would not wait, I would have put it down weeks ago. The longer you wait, you are just wasting money.

Thank you for the advice! My only concern was that if I put it down too early that, should the crabgrass not germinate until it's "normal" time, that the product's effectiveness would wear out before it could do it's job.

You should have put pre emergant down in the fall and early early spring. This will not kill any crabgrass that has started to sprout. For that you really need MSMA but good luck finding it, its been pulled of store shelves. I have had luck finding it online, you just have to search. It works like a charm, I am getting more to stockpile before its gone forever.

This is Fertilome's replacement for MSMA + a broadleaf weed killer. We have been told that it is a better chemical than MSMA.

you can try and let us know, all other msma replacement products do not work, at best they turn the crabgrass a purple brown color and it grows right back. Not sure about this stuff but msma kills nutsedge as well. We have a lot of it here as well.

I haven't tried it but I am tempted.

Reading your post made me google MSMA (never heard of it before)...
I posted it what I found.

Maybe someone else has used it and had success?

The product lasts 8 weeks, so I usually put mine down the first week of March (iowa)

This is what you want http://www.solutionsstores.com/Produ...203620506c7573

However it is banned from being sold in many states and now is only used on cotton farms and sod farms. Although it says you need a license to purchase, it can be found if you look hard enough. Make sure you know what type of grass you have bc you could end up killing your lawn.

Thanks!

Local place has it in stock.
The man said the coverage rate is one pint per acre.

I'm going halfsies with the guy next door.
I'll write up a report in about a month.

Yea I think it calls for 2-4 tbs per gallon, Ive always used 3 with no issues, maybe a little yellowing of the grass but it quickly goes away in a week.
