Abstract
Verticillium chlamydosporium isolated from eggs of Meloidogyne incognita, root knot nematode, inhibited the growth of Macrophomina phaseolina, Rhizoctonia solani Fusarium solani and F.oxysporum in vitro. In a field experiment v.chlamydosporium was found more or equally effective than Paecilomyces lilacinus, Talaromyces flavus and Bradyrhizobium japonicum in controlling the infection of M.phaseolina, R.solani, F.oxysporum and F.solani in chickpea. Combined use ofv.chlamydosporium and B. japonicum showed betler control of F.oxysporum than their separate use. Combined use of B.japonicum and T.flavus produced greater plant height and fresh weight of shoot in chickpea.
