A Technical Report from The Bartlett Tree Research Laboratories
Shot-hole disease pathogens cause some of the most common and damaging issues for ornamental flowering cherries. While the disease can be caused by numerous plant pathogens including fungi and bacteria, the fungus Blumeriella jaapii is the most common causal agent on flowering cherries. This disease can reduce the value of Prunus species in the landscape by diminishing appearance, flower set, fruit production, and fall color.
