Since about 1957 increasing numbers of apricot trees in coastal and central California counties have suffered from a limb dieback disorder that, until recently, was confused with the bacterial canker disease. This disease is now known to be caused by a fungus called Cytosporina, or in the sexual stage, Eutypa armeniacae, that had been previously reported as causing a serious limb dieback disease of apricots in Australia.
