Abstract
Use of biocontrol agent not only provide effective disease control, but it is safe and environmental friendly and being widely used against plant pathogens including Fusarium spp. Antagonistic fungi inhibit plant pathogens either directly through mycoparasitism, or indirectly through antibiosis, promoting plant growth and enhanced plant defensive mechanism. In present study, different antagonistic fungi viz., Trichoderma pseudokoningii, T. polysporum, T. harzianum, Paecilomyces lilacinus, P. variotii and Gliocladium virens were tested against Fusarium oxysporum f. sp. ciceris under in vitro and in vivo conditions. In dual assay, all the antagonistic fungi inhibited the growth of test pathogen. However, P. lilacinus produced the least inhibition of test pathogen while, G. virens produced maximum inhibition. Variations observed in the interaction between the used antagonists and F. oxysporum. The use of antagonistic fungi remains highly effective to enhance seed germination and plant growth, to reduce plant mortality and root infection as well as application of antagonists remarkably enhanced the grain yield in treated chickpea plants.
