Sweetfern blister rust caused by Cronartium comptoniae Arth. has been found on young loblolly pine, Pinus taeda L., on Maryland's Eastern Shore and in Delaware. This paper is apparently the first report of the organism in Delaware and on loblolly pine in Maryland. Only one of the two known alternate hosts was found: sweetfern, Comptonia peregrina (L.) Coult., seemed to flourish on droughty soils following intensive site preparation for planting. In one 4-year-old plantation, 21 percent of the trees had single or multiple branch infections and an additional 25 percent had stem infections.
