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)
“But what is quackery? It is commonly an attempt to cure the diseases of a man by addressing his body alone. There is need of a physician who shall minister to both soul and body at once, that is, to man. Now he falls between two stools.”
