Strawberry-growing is often handicapped by pests of one sort or another. Among these the Leaf Spot and Powdery Mildew, and at times the Botrytis Rot, are important. Growers of strawberries do not rely on spraying alone for the control of their strawberry enemies, but practice sanitation, rotation and cultivation. These measures of eradication are, of course, to be supplemented by protecting the plants with some good fungicide.
