Antagonistic potential of UV induced mutants of Trichoderma pseudokoningii against Rhizoctonia bataticola causing root rot of deccan hemp (Hibiscus cannabinus L.)

Total 35 mutant isolates were obtained from wild Trichoderma pseudokoningii after exposure to UV rays at different time intervals. Among these mutants Tpuv-M showed highest per cent inhibition (74) of Rhizoctonia bataticola causing root rot of Deccan hemp as compared to wild T. pseudokoningii. Thus mutations can induce more antagonistic potential in T pseudokoningii.
