White Rust was identified by Professor L. P. Nichols, Extension Plant Pathologist, Penn State University last September. The sample originated from an amateur chrysanthemum grower in Lehigh county. This was the first report of this disease occurring on growing chrysanthemum plants in the U.S. Plant pathologists at Rutgers University, New Brunswick, New Jersey also had received specimens of white rust from an amateur grower about the same time. New Jersey officials reported 14 separate outbreaks of white rust on amateur chryanthemum plantings.
