S36 and S37: Isolates from stems; S38, S39 and S40: Isolates from flowers; S41: Isolate from leaves. S43, S44, S45 and S55: Isolates from roots. NIC: Uninoculated with the pathogen and untreated control. IC: Inoculated with FOL and untreated control. (a) and (b): Fusarium wilt severity parameters; (c) and (d): Tomato growth promoting ability; (e): FOL isolation frequency noted after 6 days of incubation at 25°C. Bars sharing the same letter are not significantly different according to Student Newman Keuls test at P ≤ 0.05.
