Five rhizospheric bacterial cultures and cell free culture filtrates (CFs) (one strain of Gluconacetobacter diazotrophicus (35-47), two strains of Azotobacter chroococcum viz. AVK-51, HT-54: two strains of Bacillus spp. viz., RKB-91, RKB-65) were evaluated for larval mortality and egg hatching against rice root-knot nematodes (Meloidogyne gramincola) at CCS HAU Hisar. | In vitro effect of rhizobacterial strains against rice root knot nematode Meloidogyne graminicola
