Experiments were conducted both in the laboratory and screen house to study the effect of soil amendments on the population and incidence of Ralstonia (Pseudomonea solanacearum). Treatments used are soil amendments with urea, poultry manure, bagasse and ash at 0.2%, 0.6%, and 1%. Result of laboratory studies showed significantly lower populations of the pathogens in all concentrations of urea amendments, while ash amendments (0.6%, and 1%) and bagasse (0.2% and 0.6%) increased significantly the soil population of the pathogen. Result from the screen house studies showed complete control of the incidence of bacteria wilt in all concentrations of urea used. Also poultry manure at 1% amendment showed 50% survival of tomato plants while ash and bagasse showed no control of the incidence of wilt.
