| Abstract:
Bacterial wilt of tomato (Solanum lycopersicum L.), a soil-borne disease caused by Ralstonia solanacearum, has evoked interest due to its destructive nature worldwide. This study investigated the possible effect of pH on disease development, and plant growth parameters of tomato cv. FL 47 in the hydroponic culture. Seedlings were grown for 28 d in nutrient solution with three pH levels (4.5, 6.0, and 8.0) and analyzed for wilting, shoot lengths, and root length at 14 d and 28 d after inoculation. R. solanacearum caused wilt and inhibited shoot and root growth under all pH conditions. There were no significant differences between pH treatments for inoculated plants. Overall, these preliminary results highlight the role of pH on bacterial wilt and needs to be verified in the field for further studies. | |
