The US National Elm Trial is a cooperative effort to evaluate Dutch Elm Disease-resistant, commercially available American and hybrid elms for suitability for urban forest usage across a range of environmental conditions. Field trials were planted in 15 states, including Kentucky. That allowed us to evaluate elms of differing parentage, including American (Ulmus americana), Asian (U. parvifolia, U. propinqua, U. wilsonia), and hybrid cultivars, for relative susceptibility or resistance to multiple pests, including scale insects, aphids, weevils, leaf miners, gall makers, and defoliators, over seven years. Marked differences and patterns of resistance to key pests were found. This information can help city foresters, landscapers, and others to select elm varieties requiring minimal inputs for insect control, and help to support successful return of elms to streets and landscapes being impacted by serious invasive pests of other tree species.
