Abstract

Abstract: Trichodrema is considered to be the most beneficial fungal genus for protecting crops in organic systems. The present study focuses on isolation, screening and identification of salinity tolerant Trichoderma isolates from eastern Uttar Pradesh, India. Among all the Trichoderma isolates, BHUT6 and BHUT8 were highly salt tolerant under in vitro condition and showed good growth up to 1400 mM NaCl concentration. The highest salinity tolerant Trichoderma BHUT8 isolate was selected for further study. This isolate was identified as Trichoderma asperellum (accession number KU533735). T. asperellum BHUT8 also possessed temperature tolerance showing good growth up to 38 °C. The BHUT8 isolate also showed biocontrol potential against major soilborne phytopathogens namely Scletotium rolfsii, Fusarium oxysporum, C olletotrichum capsici, Rhizoctonia bataticola, and Sclerotinia sclerotiorum in dual culture assay. Amylolytic, proteolytic and chitinolytic activities of BHUT8 were also high, and produced IAA, HCN, siderophore and solubilised phosphate.
