September 7, 2012 Scouting Report
Everything: Anthracnose, Bipolaris of Bent, Brown Patch, Dollar Spot, Pythium Blight, Summer Patch, and Tim's Data Says Brown Patch and Dollar Spot
Chicago/Northern Illinois Update: Derek Settle - DSettle@cdga.org / Weather Blog
September begins to Lights, Camera, Action. In other words this summer didn't quite stop when I said so! We would see everything in a week and along the way we just kept on learning more and more. And do you know what I decided? It appears that the MOST impressive fungus on planet earth is arguably Sclerotinia homoeocarpa or dollar spot. In just a few days we saw it's developement double in untreated research plots on our creeping bentgrass greens at Sunshine Course in Lemont (30-40% blighted area became 60-80%). Furthermore, any creeping bentgrass varieties which lacked genetic resistance to dollar spot were observed to light up like a Christmas tree. Only it's not December though Santa Claus early sounded really good to most of us back in July.
Still, golf courses remain on a relatively smooth road to recovery as roots continue their deligent downward return to home (a moist and nutrient-rich rootzone is waiting). "Good health" are recent reports of greens and fairways and it means core aerification can begin on schedule for many (nothing promotes root growth/penetration more than poking holes). We continue to round what feels like the last quarter lap of the longest marathon ever run and continue to be tested. Our brains, experience and artistry has gotten a workout in 2012. I cannot remember seeing more fungal disease varieity in a week...I just relearned turf plant pathology 101, everything in 4 days!

Have a nice cooler feeling weekend. I for one will be listening to the roots grow!
