There are several diseases of the cherry tree which, if left uncurbed, may prove a serious menace to the growing of this fruit. Most cherry diseases, however, yield rather promptly to control measures - a point very encouraging to cherry-growers. But Brown Rot often runs rampant, doing considerable mischief. Other conspicuous and injurious troubles affecting the cherry are Leaf Blight, Powdery Mildew and Black Knot. These along with several other cherry diseases are common to the plum and peach.
