Pests and diseases
The resistance of 'Jackson' to Dutch Elm Disease has not (< 1995) been confirmed by artificial inoculation.[1] The species is highly susceptible to 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] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[4]
