In vitro Screening of Different Rhizobacterial Strains against Egg Hatching of Rice Root-Knot Nematode, Meloidogyne graminicola

Meloidogyne graminicola is an economic yield loss causing major pest of rice globally. For managing this pest, biological control practices act as alternate strategy, it the most effective and economic. Plant growth promoting rhizospheric bacteria (PGPR) are significant because they benefit plants both directly indirectly by enhancing plant provides long lasting antagonistic effects against parasitic nematodes. Considering in vitro efficacy research experiment nematoxicity native rhizobacterial strains was conducted, egg hatching M. at S/2 S/4 concentration levels intact bacterial culture cell free filtrates (CFCs). The behavior root-knot nematode eggs observed on days for ten which resulted inhibition all cultures levels. When compared to untreated control, Bacillus spp. showed i.e,86.8% 84.8%. Similarly, level concentration, hating such 83.7% 79.8% recorded filtrates. rate inversely proportional exposure time, decreasing increased. results revealed potential makes more feasible environmentally safe approach management graminicola.
