First report of Clavibacter michiganensis subsp. michiganensis on pepper in Indiana (US)
Clavibacter michiganensis subsp. michiganensis (EPPO A2 quarantine pest) has been isolated on sweet pepper (Capsicum annuum) from a commercial production field in northern Indiana (US). Although bacterial canker has been a common disease of tomatoes in Indiana for the past 10 year, this is the first time C. m. michiganensis is associated with pepper in this State. Symptoms on fruit are similar to those on tomato, but ;there were no conspicuous symptoms on the foliage of affected plants. There was no apparent yield losses attributable to this pathogen in the Indiana field. A similar report of C. m. michiganensis on sweet pepper was made in 1976, in California.
