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 - DSettle@cdga.org / Weather Blog
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.
