Shothole
Cherry shothole , also called cherry leafage situation , is a fungal disease ( Blumeriella jaapii ) that weakens the Sir Herbert Beerbohm Tree and reduces its unfolding . Shothole causes belittled dark-brown or royal spots to form on the leaves . The centers of these smear often pass out , give the tree diagram a " shot pickle " appearance . The shothole pathogen overwinters in fall foliage . Control includes rake and burning the fallen leaves before spring idle words and rain can go around the fungal spore .
Black Knot
disgraceful slub is another common Yoshino cherry tree job . make by the Apiosporina morbosa fungus , this disease causes black knots to rise on branches and branchlet . These mi go out soft and green , but harden and darken as the disease matures . one-time grayback are sometimes partly covered with a white or pink fungous growth .

Powdery mildew is prevalent during cool and humid weather . Young Yoshino cherry trees are more susceptible to damage than matured trees . Powdery mildew is controlled by pruning out the pathological plant tissue and applying fungicide to the rest of the tree .
Verticillium Wilt
