Article: Dingley, J.M. (1969). Records of plant diseases in New Zealand. New Zealand Department of Scientific and Industrial Research, Bulletin 192: 298 p. Wellington:. Notes: Cunningham (1931a) stated that chrysanthemum rust was common in New Zealand wherever the
host is grown. Only the uredospore stage has been recorded in this country. In some seasons it can
be of considerable importance in commercial plantings grown for cut flowers. Hudson (1946)
suggested that the disease was carried on the old stools. At the end of the season, if the plants have
been heavily infected, they should be dug up and destroyed. Salinger (1956) recommended the
application of sprays of thiram, lime sulphur, or colloidal sulphur for its control. Zineb could also
be used.
