Citrus canker is a bacterial disease which requires wet conditions for it release from a lesion and later entry to citrus plants through the stomate cells on the leaves, fruit and twigs of citrus plants.
Although citrus canker has been studied by plant pathologists for at least a century, the biological knowledge of citrus canker is continually evolving. My book in Chapter 3 covered just the very basic and well established information on citrus canker. Certain topics such as microbiology and laboratory testing were beyond the scope of my book.
This webpage provides supporting documents on the biology of citrus canker. Also, more recent events are posted on this page.
Many excellent articles can be found through browsing the internet. It may be helpful to include the scientific name for citrus canker:
Xanthomonas axonopodis pv. citri
or Xac for short. Xanthomonas is a large genus of bacteria that cause disease in hundreds of plant hosts. It also has commercial value, as certain species produce polysaccarides (xanthum gums) used in food products including ice cream, salad dressing and sauces.
The Americn Phytopathology Society has excellent technical information on citrus canker, and many of the older articles are provided free of charge.
