Apple growers in the Southeast should be familiar with the diseases that commonly strike apple trees in this region. Fire blight begins with wilting twigs, cedar apple rust with a fungus on the tree's leaves, apple scab appears as raised black spots on new apples, and powdery mildew causes a powdery substance to appear on the leaves.
