The potential of biocontrol agents Purpureocillium lilacinum (Paecilomyceslilacinus) and Trichodermaharzianum was evaluated against tomato wilt complex, caused by a combination of Meloidogyne incognita and Fusarium oxysporum f. sp. lycopersici, under both laboratory and field conditions. Biocontrol agents at spore concentration of 1 × 106 spores ml−1 were applied alone and in combined treatments. The results of combined application revealed maximum mortality and inhibition of hatching of M. incognita under in vitro conditions. Combined application of both antagonistic fungi was found to be more effective in mycelial inhibition of Fusarium oxysporum f. sp. lycopersici. In glasshouse trials, application of T. harzianum promoted overall plant growth, followed by combined application of P. lilacinum and T. harzianum; nematode development parameters and fungus damage were significantly reduced. Under field conditions, the combined application of P. lilacinum and T. harzianum increased the number of leaves, shoot length, shoot weight and root length, and decreased root weight, with minimum number of females and egg masses of M. incognita per root system and mycelia inhibition of F. oxysporum.
