What causes a tree to die?
Galls and cankers often infect fruit trees. Some of these diseases are caused by fungal pathogens, which cause branches to die and may lead to tree death. Black-knot galls, caused by the Apiosporina morbosa fungus, are warty growths on trees that commonly affect cherry and plum trees. Although young branches may die within a year of infection, larger branches may live much longer before they succumb. Cytospora, leucostoma and valsa fungal pathogens cause cankers to form on fruit trees. Bark and branches ooze a gummy residue from cracks that widen and expose diseased tissue. As the disease progresses, cankers girdle stems until branches die.
