Abstract
Relative damage due to juniper blight under field conditions was recorded on 188 species, varieties, and cultivars of juniper, cypress, false-cypress, and arborvitae during 2 out of 3 years of epidemic conditions in Illinois. Wide variation in relative susceptibility to blight was observed among the various hosts examined. No blight damage was recorded on 5 of 7 false-cypresses, 27 of 146 junipers, and 4 of 37 arborvitae examined in 1967 and 1968 at the Morton Arboretum, Lisle, Illinois, and at 3 large commercial nurseries in the state.Keywords
