Sandy loam soil having 27.3% field capacity (FC) and 34.6% water holding capacity (WHC) harboured minimum number of population of Ralstonia solanacearum PST4 (21.77 X 10 5) inciting 32.2% wilt in tomato crop. High sand content and low silt or clay content of soils was found to be unfavourable for this pathogen and wilt incidence. Effect of WHC and FC of soil on the pathogen was more evident in clay soil. The clay soil having 66% WHC and 36.2% FC harboured more pathogen causing more disease (63%) as compared to clay soil having WHC and FC.
