The sp«>rcs consist of minute black bodies just under the skin. It differs from Bitter Rot in not having the spores arranged in concentric rings. Bitter Kot attacks the green fruit, while the Black Rot only attacks the ripe fruit, and has no bitter taste. Diseased fruits should be destroyed wherever they may be found. The treatment which is used for Apple Scab is also recommended for Black Rot. Powdery Mildew (Podosphaera leucotricha). This species of Pow- dery Mildew often does much injury to young seedling Apple-trees. It appears as a powdery-like coverinp over the surface of the leaves. In late summer small black bodies appear on the leaf; these contain the winter spores of the fungus. Spray the seedlings shorUy after buds open and at intervals of three or four weeks with Bordeaux Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bethune, Charles J.
