Category: Diseases Subject: Gray Leaf Spot
The first sample of gray leaf spot was diagnosed on 7/20/01 in the Rutgers
Plant Diagnostic Laboratory from a ryegrass turf area at the New York
Botanical Garden in the Bronx. Be alert for new leaf spot activity if
you have perennial ryegrass. Diagnosis is unreliable in the field.
