Puccinia is a genus of fungi. All species in this genus are obligate plant pathogens and are known as rusts.[1] The genus contains about 4000 species.[2]


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.[3]

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.[4]
