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.
