Fusarium oxysporum f. sp. lycopersici causing tomato wilt is a common soil borne fungus. Bio-control agents could be used as an eco-friendly approach to effectively control the disease and may be advised to the farmers for profitable organic farming. The fungal (Trichoderma harzianum) and bacterial (Bacillus subtilis and Pseudomonas fluorescens ) biological control agents were tested for their compatibility in vitro to determine whether they can be used in combination. Absence of inhibition zone indicated that the biocontrol agents were compatible with each other. Trichoderma harzianum, Bacillus subtilis and Pseudomonas fluorescens were tested in-vitro for their antagonistic activity against Fusarium oxysporum f.sp. lycopersici. The antagonistic potentiality of Trichoderma harzianum was determined by 25.4% percent inhibition of the growth of the fungal pathogen (F. oxysporum lycopersici) in presence of bio-control agent (T.harzianum) and the antagonistic activity of bacterial bio-control agents revealed maximum Zone of Inhibition (ZOI) with Bacillus subtilis (29.9 mm) followed by Pseudomonas fluorescens (25.6 mm).
