Boxwood Blight: New Disease Is On the Move

Author
Daughtrey, Margery
Abstract
Boxwood blight, caused by the fungus Calonectria pseudonaviculata (also known as Cylindrocladium buxicola or C. pseudonaviculata) was first detected in the New York state in December of 2012, from samples in Westchester, Nassau and Suffolk counties at retail businesses by NYS horticultural inspectors. It then began its spread to New York landscapes. Recently installed boxwood were generally the culprits for initiating the disease outbreaks.
