Puccinia striiformis
''Puccinia striiformis'' var. ''striiformis'' is a plant pathogen. It causes stripe rust on wheat, but has other hosts as well. The species is common in Europe and in more recent years has become a problem in Australia. Infection can cause losse ...

Puccinia punctiformis'' - Canada thistle rust
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.
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.
