It's always great to get an opinion from someone who knows the biology of the plant.<br /><br />Just for clarification - we had no reports of Anguina nematode problems at Pebble before the open.<br /><br />Work by Giat et al.

The green ones were better adapted.Typically we may have thousands of biotypes on a green, although many of them may be related to each other, especially since Poa annua tends to self pollinate. As the greens age you get less biotypes Leah Brilmannoreply@blogger.comtag:blogger.com,1999:blog-7286908067123639659.post-11334784168075536872010-06-21T00:43:41.577-04:002010-06-21T00:43:41.577-04:00OK, to throw more of a monkey wrench into the mix....OK, to throw more of a monkey wrench into the mix.<br /><br />The PGA and sometimes the USGA in the past had allowed green filters to be used during the televised coverage. It is my understanding that at this year's US Open at Pebble Beach the USGA had it in its contract that NO FILTERS could be used.

Since the Poa comes from natural invasion into the greens over time, you'd have a few dozen to a few hundred different biotypes of Poa in those greens. You may also have some surviving bentgrass in low amounts here and there in the greens. <br /><br />My best guess is that in drying down the greens and firming them up, the different Poa biotypes (and Frank Wonghttps://www.blogger.com/profile/05334691162923341125noreply@blogger.comtag:blogger.com,1999:blog-7286908067123639659.post-32366686004377399592010-06-20T22:18:25.672-04:002010-06-20T22:18:25.672-04:00But surely the mottled greens are caused by someth...But surely the mottled greens are caused by something?<br /><br />Does the poa normally grow with this mottled effect? <br /><br />Apart from the hardness of the greens which has caused problems, the mottled nature of the greens does not seem to have affected the event but it would be nice to hear a reason for the patched look.Michael Greenhttps://www.blogger.com/profile/10757422314821368376noreply@blogger.comtag:blogger.com,1999:blog-7286908067123639659.post-81154085993006185062010-06-20T22:05:09.219-04:002010-06-20T22:05:09.219-04:00Sorry for the spelling...that's what happens w...Sorry for the spelling...that's what happens with my junkie crackberry!Anonymoushttps://www.blogger.com/profile/09513481244872476309noreply@blogger.comtag:blogger.com,1999:blog-7286908067123639659.post-27885437287416041232010-06-20T22:04:33.579-04:002010-06-20T22:04:33.579-04:00from my Facebook page...

The USGA is trying to show everyone that they can have great conditions without worrying about the look of the turf. I think they suceeded this week!
