September 21, 2012 Scouting Report

It's Fall: Residual Dollar Spot of Bentgrass and Summer Patch of Bluegrass, Animals/Grubs Rough Up the Rough, and Tim says Cultivar A B C D E F G

Chicago/Northern Illinois Update: Derek Settle

Midweek, a light frost on Chicago's blades of turf. I would take a look at my weather archives only to discover we hadn't been that cold since the 3rd week of May. So now the growing season works in reverse as we lose day length by about 3 minutes a day - it all happens too quickly. To be clear we had wished for our first fall day of September 22nd months ago. For most (those in the growing season trenches of 2012) that wish was about mid-July when extreme weather events had brought us to our knees both mentally and physically. Olympics weren't just on TV because we were living it! It was record pace stuff - an early green up in March segue into extreme summer drought/heat and later meteorologists would report clocking the hottest summer month ever in the United States. If you ask some they will say we were just fine.

Actually we had begun to panic, but of course we can never publicly say so. Nevertheless by about late summer (regardless of year) both human beings and plants seem to say, "What summer?" Our human mind is forgetful and plants in the landscape are just amazingly resilient. Still we should know otherwise - the watchful superintendent continues to monitor and report surface water levels are still quite low. But alas we are now well progressed into our end of season project phase. In a week a certain camera was focused less on being a scout in the name of integrated pest management (IPM). Click would follow the hum of engines that propel heavy equipment to renovate areas. Click would follow the silent germination and emergence of turf. Yep, it's fall.

Enjoy your cool, with a dash of a little wet, weekend.

Scouting Report for September 14

September 14, 2012 Scouting Report

Cool Nights Mean Normal: Dollar Spot, Rust, White Grubs, Sod Rolling Up (animals search for said grubs) and Tim says Festuca arundinacea

Chicago/Northern Illinois Update: Derek Settle

This week, temperatures were both warm and cool. Plants said Huh? Actually it meant our season was acting right again for a change as the calendar is now pretty much between summer and fall. Our jaws would drop wide open when lows dropped to 47° twice in Lemont - we've now experienced our first really cool period since June. It's a real joy when nights hold the mercury to 50° or less. The surprise/enthusiasm if you manage turf? Well if jackets are on, the trend of FEWER issues will only accelerate. Rewind. Just a week ago the landscape looked and felt like a lot of trouble. Midsummer had briefly returned to 5th gear when our nights remained warm and humid. My Everything word last week meant all major fungal diseases of turf were banging their pots and pans - should've said Yikes as eyes get real big seeing nuclear dollar spot.

But it's September and so fast-forward to normal. Normal would be dealing with moderate levels of foliar rust and dollar spot affecting Kentucky bluegrass roughs. Normal would be root damage from things like annual white grubs. Normal would be waking up to see the amazing sod rolling ability of hungry animals - grubs!?! Normal would be catching up with paperwork. Ahh, normal.

Enjoy normal and what is to be a beautiful weekend of weather!

Seedling Update


September 16, 2012
Germination is well underway on fairways 8 and 18 with the first wave of green leaf tips finding the sun and more on the way. Mild weather and a steady supply of rain have meant that irrigation from our system has not been needed as much as we originally anticipated. This is a mixed blessing however: while mild temperatures mean less moisture lost from the soil, they also mean lower soil temperatures and less heat for the plants. Remember that our time frame for a full scale re-seeding of fairways would be undertaken three to four weeks sooner than this project was, in order to provide maximum heat and sunlight for our seedlings.

I have been asked on several occasions why the turf killed with Roundup prior to seeding was not removed prior to seeding. While it may appear counter-productive, this layer of material serves multiple vital functions. This layer forms a barrier against erosion should we receive heavy rain or wind, and predators who would make a meal of our precious seed. It also holds moisture and keeps it available to the infant plants as they develop. Anytime you've seen seed covered with mulch or straw, (the thriving seed to the left of 18 approach is a prime example) the material was added to serve these very same purposes. To strip this layer only to replace it with another material to serve the same purpose would cost unneeded time, money, and effort.

See you on the course!

Scouting Report for September 7


~~The following is the C.D.G.A. scouting report as posted by Derek Settle, PhD. Don't forget to follow the link!~~

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

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!

Aerification Update


Nelson aerifys one fairway.

As aerification week comes to a close it is in now way hyperbole to call it a success. In spite of repeated rains and temperatures in the nineties, the greens were deep-tined, topdressed, dragged and fertilized. Cores were pulled on every tee, the cores were broken up via drag mats, and the tees were fertilized. The time consuming process of aerifying fairways began yesterday with holes one, two, nine, and the main body of eight. This process will continue throughout the next week and amidst play and only one fairway will be worked on at a time. Should you find your ball surrounded by pulled cores, simply clear enough area around your ball for you to swing and have at it.

The eighteenth fairway and number eight approach fairway were seeded Wednesday and Thursday! I must remind everyone that both of these areas will be closed to carts until further notice.  This is being done for the safety of our seedlings; players should also be aware that both of these areas will be irrigated every hour on the hour. Seedlings have very little root structure, and must have near constant access to water to survive. Remember that our irrigation program runs heads in a progression from green to tee. So if you're facing the green, standing over an irrigation head and there's a head on in front of you, you have less than five minutes to decide whether you'd like to stay dry.

See you on the course!
