Taxonomy

Examples of Puccinia rusts and the diseases they cause:

• Puccinia asparagi - Asparagus rust
• Puccinia graminis - Stem rust, also known as black rust
• Puccinia horiana - Chrysanthemum white rust
• Puccinia mariae-wilsoniae - Spring beauty rust
• Puccinia poarum - Coltsfoot rust gall
• Puccinia psidii - Guava rust or eucalyptus rust
• Puccinia recondita - Brown rust
• Puccinia sessilis - Arum rust and Ransoms rust
• Puccinia striiformis - Stripe rust, also known as yellow rust
• Puccinia triticina - Wheat leaf rust, also known as brown rust
• Puccinia punctiformis - Canada thistle rust[3]

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]
