Pests and diseases[]
No other specific information available, but the species generally is highly susceptible to Dutch elm disease and Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola,[2] and highly preferred for feeding by the Japanese Beetle Popillia japonica [3][4] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[5][6]
