Erysiphe platani, also known as sycamore powdery mildew, is a fungus native to North America that now infects sycamore tree species worldwide.[2] Infections may spread rapidly in urban settings with large groups of young trees or in plant nurseries.[3] This mildew thrives when there are high humidity conditions during the growing season.[4]
Symptomatic trees show leaf discoloration and puckering as the mildew spreads across buds and leaf surfaces.[5] The most visible effects, which include "leaf curling, stunting, and distortion,"[6] appear on vulnerable newly emerged leaves.[4] This infection only appears on leaves, it has no obvious effect on stems and branches.[5] Fertilization and pollarding increase the number of young shoots, which are the parts of the trees most vulnerable to infection.[6]
