Abstract:

This study assessed the occurrence and severity of Ralstonia solanacearum (E. F. Smith) Yabuuchi et al. in the soil of seven tomato growing areas in Lantapan, Bukidnon. Soils collected at 20cm, 40cm, and 60cm depth were assessed for the presence of Ralstonia solanacearum (E. F. Smith) Yabuuchi et al. using Kelman’s Tetrazolium Chloride (TZC) medium. Result of the study reveals that the seven communities were infested with R. solanacearum (E. F. Smith). The highest bacterial plate counts were observed at 20 cm soil depth that differed significantly from 40cm and 60cm depth in all barangays. Among the barangays, Basak had the highest bacterial count that also differed significantly from that of the other barangays. It is recommended that solanaceous crops not to be planted while the bacterium can still be recovered in the soil. A follow-up study should be conducted to determine if the strains of R. solanacearum (E. F. Smith) Yabaguchi et al. are presently affecting tomato in Lantapan, Bukidnon.
