Abstract
A significant increase in growth parameters in terms of shoot length, shoot weight and a significant reduction in infection of Fusarium spp, Rhizoctonia solani and Macrophomina phaseolina was observed where Rhizobium meliloti treated seeds of mash bean and sunflower were used in Melanothanus afaqhusainii amended soil. Combined use of Pseudomonas aeruginosa with sea weeds viz., Melanothanus afaqhusainii, Padina tetrastromatica, Cystoclonium purpuraeum and Hypnea valentiae significantly reduced the infection of M. phaseolina and R. solani on mash bean and sunflower followed by R. meliloti and B. subtilis in combination with C. purpuraeum and M.afaqhusainii respectively on mash bean and sunflower. Seed treatment was found more effective method in controlling the root infecting fungi as compared to soil treatment.
