Looking for some advice and input regarding bentgrass varieties.  We are planning to gass (with methyl bromide) and regrass our greens next year and are considering using one of the following:

A1;
A4;
A1/A4 mix;
T-1; or
007.

Most of the courses around us in St. Louis are using A4, but there are a couple that have gone with T-1.  We are experimenting with different varieties on some of our practice holes and in the nursury to see how they work out. I just wanted to see what the collective wisdom of the board is on the subject.

Thanks.

I assume you were snickering when your typed this.

Hazeltine is undertaking the same project next year.  You may want to check with Jim Nichol to find out what they are using. 

Also, I think Butler National gassed and regrassed a few years ago.

Prairie Dunes did as well...

I spoke with Stan at PD recently about their grass choice.  Since some NTEP trials label the "A's" as most poa resistant, his members wanted to go with those.

If its any help, in Topeka we are seeding with a more moderate maintenance L93, based on success of other supers in the area. We also considered T-1/007, LS44/L96 a few other choices.  There are so many choices now, it really depends on what is important to you.  And, most choices result in variations so minor that most of your members won't really know the difference without you telling them. 

But, the discussions can go on for weeks, months and years.  I mean really, I hear more discussion on grass varieties at the country club now than I ever heard back in my college dorm days.

No sniggering, I guess I am too used to speaking like a lawyer!  Thanks for the bump.

Jeff:

Thanks for the input.  Many of the private courses have gassed and regrassed and most stripped the greens and went A4.  One went T1, but kept the thatch, or at least some of it.  They have had some problems filling in problem areas and have tried to include some A4 mixed with the T1 to fill in.  That in and of itself would make me somewhat cautious (we will be stripping our greens, however).  I wasn't sure if the mixes how you could be consistent (not that I could ever tell), but it would seem you might have variations from green to green as the mix could never be completely the same.  Until our Greens meeting, I hadn't heard of 007 before.

We gassed and regrassed with A-1 last year.  The greens were gassed the 1st week of Aug. 2008 and the last green was seeded on Sept. 11th.  We had a pretty short window (reopened May 29th 2009) but the greens turned out excellent and remain so today.  So far so good with A-1. The key with any grass you go with is to manage it properly.  The book Creeping Bentgrass Management by Dr. Dernoden is an excellent source.

Steve,
We are using A1-A4 mix and have been for the past couple of years. Not sure where your located but all the greens where we have used this mix are in excellent shape. You gotta abuse them with consistent verticutting and light topdressing and maintain an eighth or lower but if these practices are incorporated you can create some pool table quality greens.
