Pest Alert № 1 — Pythium Blight
Pythium blight, P. aphanadermatum, was found today while scouting a creeping bentgrass fairway and tee with a history of this disease on the Bob Berry Sunshine Golf Course in Lemont, IL. This is perhaps the most feared disease of golf course superintendents because damage (turf infection then death) occurs very rapidly. Associated with overly wet conditions during summer periods = Chicago is currently experiencing.
Areas where drainage is lacking are most susceptible to damage by Pythium blight. Of turfgrasses we use, perennial ryegrass is highly vulnerable, whereas creeping bentgrass can recover if blight is caught early.
It’s time to have preventive programs in place. Pythium-specific plant protectants required. It’s time to Scout!
