The Problem

Early Blight

Early blight (sometimes called target spot) is a fungal disease that most often affects tomatoes and potatoes. It starts by causing distortion of the new growth, followed by brown or black spots. Gradually the whole plant withers, yellows and dies. The disease is difficult to treat once established but its entry into the plant can be prevented by spraying with a protective fungicide. Early blight often occurs during humid weather and is most likely to attack plants under stress. Remove dead or damaged leaves and make sure there’s good air movement around the plant.
