The dollar spot study at North Shore Country Club in Glenview has now ended. The final months of the fairway fungicide study was interesting from the standpoint that ideal conditions for rapid foliar disease development pretty much only occurred in early October. A time when rain, high humilities and cloud…


Each growing season is different. For me it will be the 8th in total I’ve experienced in Chicago. On that, I count 2006, 2007, 2008, 2009, 2010, 2011, 2012 then… 2021! I took a sabbatical?

This one turns out to be more about inconsistencies than anything else. We started off…


It turns out at least one insect had a pretty good go this summer. Enter the fall armyworm. How bad did it get? Considered by some the worst they had seen in about 20 years (Atlanta, GA golf course superintendent). …


Recently, the diagnostic samples of greens were not exactly the usual. We are experiencing a warm stretch of weather into fall. It has been dry, except for an occasional rain shower. However, a leaf spot of creeping bentgrass can and does occur during warm periods.

Red leaf spot of creeping…


The growing season of 2021 is now entering a “shoulder season”. Hello fall. Days are shorter. Temperatures are cooler. And dollar spot (usually) takes off like a rocket. That hasn’t happened yet. Why? Well, look at your Midwest landscape. It’s pretty dry. And that has been the story of this…


It’s that time of year in Chicago. One of the things you realize when you get to the upper Midwest (the Great Lakes to be exact) is that it can get wet. When does it see the most rain? Well it turns out to be in the months of July…


Golf greens with a high proportion of annual bluegrass or Poa annua are susceptible to a fungal root disease known as summer patch (Magnaporthe poae). This is the same disease that can be problematic in Kentucky bluegrass lawns each summer. There’s a famous photo (if you are a turf disease…


Dollar spot activity has officially begun. How do I know? It’s called research.

Objective: Evaluate fungicides and programs for efficacy and turf quality.

Sponsor: Matt Giese, Syngenta

Data: Visual quality (1–9 scale, with 6 or greater acceptable), Reflectance using NDVI (Normalized Difference Vegetation Index), Dollar spot number per plot, Dollar…


My first sighting of a fungal disease called anthracnose, Colletotrichum cereale, occurred earlier this week. This is not an old friend. It’s the enemy of Poa annua or annual bluegrass. It is the primary reason Poa was sent on its way. Chicago golf courses began an intensive overhaul of her…


Its’s Frisky Fairy Ring Friday! Well, at least that’s become a popular thing on Twitter hasn’t it? (for those with fairy rings in the myriad of turfgrass environs) Which brings me to the point of this alert. We have begun to see more and more fairy ring activity in Chicago…
