Use of Pseudomonas aeruginosa alone or in combination with fungi viz., Verticillium chlamydosporium, Paecilomyces lilacinus, Talaromyces flavus, Trichoderma harzianum and Stachybotrys atra significantly (P 0.05) reduced infection of Meloidogyne javanica root knot nematode and root infecting fungi viz., Macrophomina phaseolina, Rhizoctonia solani, Fusarium solani on mungbean and mashbean. Soil treatment with P. aeruginosa and V. chlamydosporium reduced gall formation mostly on mungbean, whereas P. aeruginosa mixed with T. harzianum showed greater reduction in gall formation on mashbean. P. aeruginosa used alone or in combination with V. chlamydosporium or P. lilacinus also significantly reduced egg mass production and number of juveniles in soil. P. aeruginosa used with fungal antagonists also significantly enhanced plant growth.
