Pest Resistant Landscape Plants
Richard E. Bir and Thomas G. Ranney
Reducing pesticide usage while utilizing attractive landscape plants has been the goal of many research programs. At the Mountain Horticultural Crops Research and Extension Center, we have been evaluating landscape plants for pest resistance under the high pest pressure conditions of the southern Blue Ridge Mountains. Resistance to Japanese beetle foliar feeding and depredations from eastern tent caterpillar on flowering trees plus disease resistance on Cornus kousa and allegedly pest-resistant shrub roses revealed plants displaying a wide range of pest resistance.
Eighty-five different taxa of woody plants were included in these tests. Tables shown here include a representative sample of those plants. For a complete listing of these plants as well as experimental methods, please consult the research papers referenced. The relative terms: poor, fair, good, and excellent were developed for ease of comparison. Poor resistance to disease indicates that the test plant became
