Notes: Both rust and host [Cirsium arvense] are introduced. The host is a troublesome weed
throughout New Zealand. Experiments have been carried out without success to use this
rust as a biological control of this weed (Cunningham, 1927a) but it has always proved
impossible to establish a heavy enough infection to eradicate the weed.
