Description: Diamond?shaped lesions occur near the base of the stem. Lesions are tan with dark brown borders. Infected stems wilt, producing the characteristic "shepherd's crook" symptom. When crowns are invaded the inner tissues turn bluish-black and the plant dies.
Location: Anthracnose occurs throughout Ohio on susceptible alfalfa varieties.
Time of attack: Anthracnose occurs during relatively hot weather, from June through September. The spores are spread from plant to plant by splashing rain or by means of infested harvesting equipment.
Management:
