It’s been distinctly non-diseasey so far this year, but dollar spot is revved up and ready to go with this forecast for next week

Watching the drone app in our study this morning had me envisioning a not-too-distant future where AI monitors local conditions and uses disease predictive modeling to send out drones to apply pest mgmt tools with minimal input from humans. Interesting and exciting times ahead!

Brown patch (on green) and Pythium blight (on collar) have been seen at the OJ Noer. And in true research fashion, none of it is on our brown patch or Pythium blight studies of course. Get some appropriate fungicides down if you haven’t already.

We know that the N fert decreases dollar spot, but we don't know why. Our most recent paper led by Shashi Welmillage suggests that N influences the microbiome, specifically increasing oxalic acid-degrading bacteria, which leads to reduced disease. Give it a read! doi.org/10.1094/PHYTO-…

Can’t thank this crew enough for all the excellent work they’ve put in this summer. Congrats to mustache boy (aka ⁦Kurt Hockemeyer⁩) on his sudden death victory in the lab championship mini golf outing today. Time to start wrapping up summer trials and prep for snow mold!
