    With this unusual winter/spring development, it would be interesting to note when, the CG actually shows itself, in your Zone...

    Everybody has areas they come across, that grows CG, i.e.,,, in a ditch or something...

    PLZ post your findings as they begin... :)

    Already found some here in N.E. Ohio. Soil temps. are in the low 60's . Was out treating on Saturday and have a customer that has only done a couple treatment per season. I usually hit him on round 2 and 4, as he just wants the weeds controlled and some green. Last year his lawn was loaded w/ crabgrass and wanted a pre-emerge put down this year. I found some crabgrass already germinated in a few bare spots. I'm using Dimension this year so I guess we will see how good it works as a post-emerge. After all the record highs last week, we are going to have a low in the low 20's, so I'm thinking that will take out any early crabgrass.

    I could not believe it Sunday March 25th. But today on the 26th of March I checked again. I checked at the foreclosed house which had a poor, neglected yard. Heavy crabgrass last year.
    Its about a 3/8th inch tall at maximum; it definitely looks like crabgrass. Michigan 2112. Photos soon.

    Temps of 29 expected tonight--its 39 degrees now. Soil temps about 60 last week. Mowed once.

    The weed weather chart shows crabgrass control requirement way ahead of 2112. It shows treatment dates as "late" but not yet "Done".

    This is very interesting information...
    I just started seeing the cool season grasses emerge last week or so, but now with the cold snap in place, I don't expect CG to emerge just yet, in this area... we'll see?!!??
    thanx for the replies... :)

    I've mowed a couple of accounts the past few days. I've never had to mow in March for the 30 years I've been at this gig !!! This is a first for me.... I need to get at least 75% of my accounts mowed in the next few days. Well I guess this will help to make up for a non-existent winter !!!!! I only got one mowing in last April due to the cold and overly wet conditions....So I guess I'm getting a little payback for a lame 2011 spring !!!!!

    I can hardly believe it. Weather has been at record warmth most of the last two weeks. It hit 87 at one time a few days ago.

    Crabgrass has appeared on a neglected lawn across the street. Soil temperature is about 50 today, even though we had temps of 33 last night, and soil temp was warmer a few days ago.

    A few dandelions have also bloomed.

    my yard was invaded with those dandelions last year. They sold me some Escort XP this year. I hope it helps.

    no crab here yet, and this most recent cold snap helped for sure. That said, I bet dealers are kicking out WAY more dithopyr product this season than prodiamine.

    Its been a few years since I have used Dimension but man do I love the clean spread without the yellow.

    Dont make me more nervous than I already am, this is my first year using prodiamine, usually go with dimension. had planned on switching to dimension later in the round, hope we can get to the 3rd week of April with prodiamine....otherwise my plan is screwed....

    I think you'll be fine. I decided to split app Dimension this season cause the season is like 5 weeks longer than normal. Not even sure Barricade would last as long as we need it to...perhaps....but I went safe route with Dimension.
