Survival of Clavibacter michiganensis subsp. michiganensis
In Iowa, US, the dynamics of epiphytic populations of Clavibacter michiganensis subsp. michiganensis (EPPO A2 organism) were studied regarding their survival and dissemination. C. m. michiganensis survived for at least 24 months in infested debris at the soil surface. The survival was only 7 months in buried debris. Overwintered, infested debris served as as a primary inoculum for establishment of epiphytic populations of C. m. michiganensis on a subsequent tomato crop.
