Abstract

In Nigeria, most strains of Ralstonia solanacearum, the causative agent of tomato bacterial wilt disease; belong to race 1 biovar III (RIB3). Control strategies to assuage its destructive effect are highly necessary. A randomised complete-block design (RCBD) was used for the experiment. Thymol (0.7%) and Acibenzolar-s-methyl (ASM, 30 and 15 µg/ml) were used. Results indicated that the combination of thymol and ASM recorded the highest numbers of days for fruiting in Beske which were 74 and 75 while 59 and 60 days were recorded for UC82-B in both early and late seasons, respectively. When thymol and/or ASM were applied, bacterial wilt disease incidence and disease severity were significantly reduced and this was translated to a significant yield increase when compared with the untreated control plots. The results suggested that the combined application of thymol and ASM could be advantageous to tomato-growing farmers where R. solanacearum is prevalent.
