Summary Studies on the survival ofPseudomonas solanacearum, the causal agent of bacterial wilt of tomato, under laboratory conditions showed that soil amendments had little effect on the population of the pathogen. When the host plant was grown in amended soil there was a positive influence on growth of the pathogen. The population level of the pathogen incorporated into the soil was reduced to one-half within a period of 46 days. The pathogen survived in the rhizosphere of non-host plants belonging to the families Acanthaceae and Leguminosae even in the absence of the natural hosts, but its incidence in the rhizosphere of plants belonging to Graminae and Cyperaceae was comparatively low indicating possibilities of reducing the inoculum potential of the pathogen in tomato fields by allowing such plants to grow during fallow periods.
