Epidemiological aspects of bacterial canker of tomato

Rifampin-resistant strains of Clavibacter michiganensis subsp. michiganensis (CMM$\sp{\rm rif+})$ were used to study the epidemiology of bacterial canker of tomato (Lycopersicum esculentum Mill.). Clipping tomato seedlings in transplant beds with a rotary mower transmitted CMM$\sp{\rm rif+}.$ The incidence of systemically infected plants in production fields increased about 10% for each 0.1% increase in incidence of infected seedlings in the transplant beds. When healthy and diseased seedlings were harvested and mixed in bundles at various rates, CMM$\sp{\rm rif+}$ was spread from diseased to healthy seedlings. Incidence of systemically infected plants in production fields increased about 3-5% for each 1% increase in the percentage of diseased seedlings.
