Abstract

Rhizospheric fungal antagonists activity against phytopathogen by production of volatile and non-volatile metabolites. In vitro assessments revealed their antibiosis and mycoparasitic ability to affect growth of the pathogen. Soil borne fungi, bacteria and actinomycetes were identified and used as antagonistic microbes against some soil borne pathogens. The efficacy of volatile and non-volatile metabolites produced by 14 selected dominant microbes against the common fungal test pathogens (F. oxysporum f. sp. ciceri & lini) were suppressed with colony interaction, volatile, and non-volatile metabolites emanated from different leaf surface microbes like Aspergillus niger, A. terreus, A. luchuensis, Trichoderma harzianum, Penicillium citrinum, Streptomyces rimosus, and S. aureofaciens and prior application of these antagonists effectively reduced the development of Fusarium wilt in chick pea and linseed.
