Abstract
Infection of pruning wounds by epiphytic populations of the bacterial canker pathogen, Clavibacter michiganensis subsp. michiganensis, incre ased the amount of diseased foliage and vascular colonization in field -grown tomato plants in 1991 but not in 1990. Pruning significantly re duced yield from inoculated plants compared with nonpruned inoculated plants in 1991 but not in 1990. Inoculation significantly reduced esti mated yield in both years. Pruning had no effect on disease developmen t or yield in noninoculated tomato plants.
