Examples of Puccinia rusts and the diseases they cause:

The rust species Puccinia obtegens has shown some promise for controlling Canada thistle, but it must be used in conjunction with other control measures to be effective.[4]

Another leaf rust species, Puccinia myrsiphylli, has been used as an effective biocontrol agent for infestations of the common form of bridal creeper (Asparagus asparagoides) in Australia since 2000.[5]
