Epidemiology and host morphology in the parasitism of rush skeletonweed chondrilla juncea by puccinia chondrillina

Epidemiology and host morphology in the parasitism of rush skeletonweed chondrilla juncea by puccinia chondrillina

P. chondrillina was released in 1978 in the Spokane River Valley near Spokane, Washington [USA], in an attempt to control rush skeletonweed (Chondrilla juncea). The pathogen spread 3, 5 and 10 km from the original release site by 1980, 1981 and 1982, respectively. About 5, 11 and 10% of the leaf and stem surfaces were covered by uredia in 1980, 1981 and 1982, respectively. The rust significantly reduced number of flowers, seed viability and plant size each year but to date has not significantly reduced the population of rush skeletonweed.
