This presentation will aid consultants, growers, and practitioners understand how to identify and manage early blight of potato in the field and storage. Key symptoms are described that help to differentiate this disease from other common diseases. Important details of the pathogen, host, and disease cycle are discussed. Managing early blight in the field requires careful integration of cultural and chemical methods, including rotation, choice of cultivar, plant nutrition, and fungicide application. Understanding the roles of these elements in managing early blight helps to reduce losses in yield and tuber quality and to reduce reliance on weekly application of fungicides.
