First report of the oak wilt fungus, Ceratocystis fagacearum, in New York State
Plant Disease 93 (4), 428-428
Abstract: During 2008, red oak trees (Quercus rubra) growing in New York State, U.S.A. were observed with symptoms of oak wilt, caused by Ceratocystis fagacearum. The endoconidial state of the oak wilt fungus, Thielaviopsis quercina, was isolated from the diseased plants. The identification was based on morphological characteristics and ITS sequence analysis. Prior to this discovery, north-central Pennsylvania was considered to be the northeastern limit for oak wilt occurrence in the United States.
