Abstract:

All the three bicontrol agents were found to be compatible with each other. Among the various oilcake extracts tested, mahua cake (10%) inhibited the mycelial growth of F. oxysporum to an extent of 60.77 per cent. The crude antibiotic extracted from Pf1 showed maximum growth inhibition of F. oxysporum up to 63.33 per cent. The diffusible non-volatile metabolite of Tv1 was effective in retarding the growth of the pathogen up to 91.44 per cent. The volatiles released by Tv 1 reduced the growth of the pathogen by 87.55 per cent. Production of HCN was observed to be in higher quantity in Pf1 and Pf2 while isolates of B. subtilis did not produce the same. Two isolates of P. fluorescens (Pf1, Pf2) and T. viride (Tv1 and Tv2) produced siderophore whereas the isolates of B. subtilis (Bs2, Bs10) were negative for the same.Pf1 and Pf2 produced more SA than Bs2 and Bs10
