Bacterial canker of tomato caused by Clavibacter michiganensis subsp. michiganensis (Cmm) causes significant yield losses on tomatoes. It is newly observed bacterial disease in mid hills of Himachal Pradesh, India. Few or less work has, therefore, been done on this disease in the state. This study was conducted to find optimum growth conditions for the bacterium. Under present investigations, five isolates of Cmm were thus isolated and maintained in pure cultures. |
