dc.description.abstractFusarium oxysporum f. sp. lycopersici is the pathogen of tomato wilt, a disease of great economic importance worldwide. Although application of synthetic fungicides such as thiophanate methyl and mancozeb can prevent the occurrence of this disease, their effects on the physical environment especially, is a limiting factor. Botanicals, i.e. plantbased fungicides are now being preffered for controlling fungal pathogens because they have minimal environmental impact and are less dangerous to consumers in contrast to synthetic fungicides. Teak leaves have been reported to possess a very great antimicrobial activity because of their high content of phytochemicals. In an effort to develop eco-friendly chemical strategy for control of Fusarium wilt disease of tomato plants, in vitro effect of 10, 30 and 50% (w/v) concentrations of the aqueous and ethanolic leaf extracts of teak (Tectona grandis L.) on the radial growth of the mycelia of Fusarium oxysporum f. sp. lycopersici was investigated using the pour plate method. Results of the study revealed that both extracts retarded the radial growth of mycelia of F. oxysporum f. sp. lycopersici compared to that of the control, with the ethanolic extract having a greater effect at the concentrations tested in this study. It is therefore recommended that an in vivo study of effects of the same leaf extracts on wilt – infected tomato plants be conducted.
