Abstract

Experiments were carried out under greenhouse conditions to test the efficacy of Pasteuria penetrans (Thorne, 1940) Sayre and Starr (1985) in combination with five nematicides viz., aldicarb, carbofuran, miral, phorate and sebufos for control of Meloidogyne javanica (Treub, 1885) Chitwood, 1949 on tomato var. Pusa Ruby. Results revealed that the application of P. penetrans in combination with nematicides significantly improved plant growth characteristics and the increase in growth was more than additive when compared with their individual effects. Combined application resulted in additive reduction of M. javanica galling. When P. penetrans and nematicides were applied together, there was a high degree of nematode control wherein a maximum of 89.37 per cent reduction in final nematode population was recorded with P. penetrans and carbofuran combination.
