Do not starve the turf during the summer months. Very light fertilizations with a balanced fertilizer during the summer may help the turf withstand stresses and recover quickly from anthracnose damage. Low, frequent mowing enhances disease development. Areas prone to localized dry spots are more susceptible to anthracnose damage. Follow a rigorous program to reduce damage from localized dry spots.
All products work best when applied on a preventive or early curative schedule.
Applications after development of severe damage to putting greens are not very effective. Preventive applications of reduced rate tank mixes of a DMI fungicide and chlorothalonil at two-week intervals have provided good control of anthracnose in studies conducted in Kentucky. Fungicides listed in the table are labeled for anthracnose control.
