Abstract

The effcacy of the bacterial spore parasite, Pasteuria penetrans (Thorne, 1940) Sayre and Starr, 1985 in combination with four oil cakes viz ., castor ( Ricinus communis L.), gingelly ( Sesamum indicum L.), groundnut ( Arachis hypogaea L.) and neem ( Azadirachta indica Juss.) was tested under greenhouse conditions for the control of Meloidogyne javanica (Treub, 1885) Chitwood, 1949 on tomato cv. Pusa Ruby. The bacterium as well as oil cakes reduced nematode infestation and improved plant growth, but the combination treatments were significantly superior. Among these, P. penetrans applied in combination with neem cake was the best treatment giving 75. reduction in final nematode population.
