Canker

Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease.

Examples

• Apple canker, caused by the fungus Neonectria ditissima (formerly Neonectria galligena.)
• Ash bacterial canker, now understood to be caused by the bacterium Pseudomonas savastanoi, rather than Pseudomonas syringae. After DNA-relatedness studies Pseudomonas savastanoi has been instated as a new species.
• Butternut canker, caused by the fungus Sirococcus clavigignenti-juglandacearum
• Bleeding canker of horse chestnut, caused by the bacterium Pseudomonas syringae pv. aesculi
• Citrus canker, caused by the bacterium Xanthomonas axonopodis
• Cypress canker, caused by the fungus Seiridium cardinale
• Foamy bark canker of oaks in California, caused by the fungus Geosmithia putterillii
• Dogwood anthracnose, caused by the fungus Discula destructiva
• Grape canker, caused by the fungus Eutypa lata
• Honey locust canker, caused by the fungus Thyronectria austro-americana
• Larch canker, caused by the fungus Lachnellula willkommii
• Mulberry canker, caused by the fungus Gibberella baccata
• Oak canker, caused by the fungus Diplodia quercina
• Pine pitch canker, caused by the fungus Fusarium circinatum
• Plane anthracnose, caused by the fungus Apiognomonia veneta
• Poplar canker, caused by the bacterium Xanthomonas populi
• Rapeseed stem canker, caused by the blackleg fungus Leptosphaeria maculans
• Rose cankers, caused by the fungus Leptosphaeria coniothyrium and Cryptosporella umbrina
• Scleroderris canker, caused by the fungus Gremmeniella abietina
• Southwest canker, caused by environmental conditions (frost damage and sun-scalding)
• Strawberry anthracnose, caused by the fungus species complexes Colletotrichum acutatum and C. gloeosporioides (incl. C. fragariae)
• Tomato anthracnose, caused by the fungus Colletotrichum coccodes
• Willow anthracnose, caused by the fungus Marssonina salicicola
