Abstract


Pseudomonas aeruginosa and Paecilomyces lilacinus used alone or together significantly (P 0.05) reduced infection of Meloidogyne javanica root knot nematode and root infecting fungi viz., Macrophomina phaseolina, Rhizoctonia solani, Fusarium solani and F. oxysporum on pumpkin (Cucurbita pepo), guar (Cyamopsis tetragonoloba), chilli (Capsicum annuum) and watermelon (Citrullus lanatus). P. aeruginosa was more effective than P. lilacinus in reducing the M. javanica root knot nematode infection. Combined use of P. lilacinus and P. aeruginosa was more effective in reducing the infection of root knot nematode in guar, M. phaseolina and F. oxysporum on pumpkin and F. solani on guar and watermelon than either used alone.
