Abstract
Plant growth promoting-rhizobacteria (PGPR) contributes a significant part in crop health improvement including pest management. It also protects plants from parasitic nematodes damage by exhibiting biocontrol activity besides improving the growth of plants by supplying nutrients, producing phytohormones and inducing modification of plants metabolisms. PGPR decreases or inhibits the hatching of nematode juveniles and suppresses the nematodes development and reproduction by exhibiting various mechanisms such as hyperparasitism, antibiotic synthesis or antibiosis, substrate competition, synthesis of lytic enzymes and induction of resistance in plants. Hence, PGPR could be an efficient biological protective agent that protects agricultural and horticultural crop plants from the infestation of parasitic nematodes.
