Borer Damage in Green Ash Trees from Different Provenances    (View PDF)

Frank S. Santamour, Jr. and Kim C. Steiner

Abstract: Young trees of green ash (Fraxlnus pennsyivanica) from 43 geographic origins throughout the species' range were heavily attacked (81 %) by the ash borer (Podosesia syringae) or its sibling species P. aureoclncta, with no differences among provenances. Faster growing trees were attacked more often than weak trees. The few fast-growing, borer-free trees remaining are being vegetatively propagated and used in controlled crosses to develop populations for further testing.
