Pests and Diseases
Natural populations of Japanese Elm have a low to moderate resistance to Dutch elm disease. In trials in the Netherlands, susceptibility to disease was found to be commensurate with rate of growth, the more vigorous specimens exhibiting far more foliar damage after inoculation with the causal fungus. Careful selection in North America has produced a number of cultivars highly resistant to disease (see Hybrids, hybrid cultivars and cultivars below). The tree is resistant to the Elm Leaf Beetle Xanthogaleruca luteola but is moderately susceptible to Elm Yellows.

Famous quotes containing the words pests and/or diseases:
“How we love sequestering, where no pests are pestering.”
—Lorenz Hart (1895–1943)
“The fantasies inspired by TB in the last century, by cancer now, are responses to a disease thought to be intractable and capricious—that is, a disease not understood—in an era in which medicine’s central premise is that all diseases can be cured.”
