Black Rot (Macrosporium tomato) : This fungus produces roundish, black velvety areas on the fruit of the tomato. The spores are many-celled, and sooty-colored, and are borne on threads covering the diseased spots. Sometimes the leaves and stems are also affected. Treatment: Spray with Bordeaux, beginning when the flowers open, and repeat at intervals of ten days or two weeks.. Cut Worms (Agrotis ypstton). After Riley.

Treatment : Spray with Bordeaux a week after transplanting, and again at intervals of two weeks. Scab (Cladosporium fulvum) : Olive-brown, felt-like areas occur on the under side of the leaves and brown discolorations on the upper surface.
