Kentucky Bluegrass Disease Diagnosis
I have struggled to diagnose the disease in my Midnight Kentucky Bluegrass since May. The problem partially subsided during the summer, but started getting worse again in late August. Dollar Spot is my best guess, but the characteristic lesions are not present and I have not observed mycelium at any point. The green color of the blade just quickly fades to white.
Any thoughts would be greatly appreciated!
Please excuse the weeks. The KBG was slow to establish and is less than a year old, so I'm not applying herbicide until fall.
