Influence of two Pasteuria penetrans bacterial isolates at different application types on root -knot nematodes (Meloidogyne spp.) [electronic resource].

Includes references.

Two P. penetrans bacterial isolates namely: Pp Japanese and Egyptian were used at different three types: pp infected root powder, spore suspension and attached larvae as a biocontrol agent against root-knot nematodes, Meloidogyne spp. on tomato plants under greenhouse conditions. Results revealed that the effective treatment obtained with Pp Japanese isolate as a pp root infected powder, where all nematode parameters significantly reduced compared to plants treated with nematode alone. Egyptian isolate appeared promise result when applied also as a pp root infected powder and as a spore suspension. The lowest effect was noticed with Japanese isolate when applied as attached larvae. Results indicate that the highest Pp infected females recorded with Japanese isolate as a root powder, followed by Egyptian isolate as a spore suspension, whereas the lowest Pp infected females recorded with Japanese isolate as a attached larvae. Key words: Root-knot nematodes Meloidogyne spp.; Pasteuria penetrans; Tomato (Lycopersicon esculentum Mill).
