Bacterial Canker of Tomato, (A Commercial Growers Guide) 

Bacterial canker is a serious tomato disease caused by Clavibacter michiganensis subsp. michiganensis (Cmm). The disease was first discovered in 1909 in Grand Rapids, Michigan, USA but is currently reported in tomato production areas worldwide and outbreaks occur annually. However, preventive measures can be taken at all stages of production to avoid losses from bacterial canker.

These guides have been developed and published by ASTA, with sponsors from the seed industry and contributions from public and private researchers.  They are available for download on the CSA website in English and Spanish.
