Abstract

The biocontrol agents (Pasteuria penetranx and Trichoderma viride) and botanicals  (neem and castor cakes) were evaluated either singly or in combination (at 1/2 and 1/3 of the  dosages) for the management of root-knot nematode. M. incognita, infecting tomato under  glasshouse conditions. Combined application of R penetrans, TI viride and neem or castor cake at  1/3rd dosages was significantly superior compared to their .individual applications in terms of  increased plant growth and reduced root galling, egg mass production and final populations of M.  incognita. Similarly, total parasitisation by bioagents was higher in plants treated with these  treatments, in terms of number of juveniles encumberred and adult females infected with the  bacterium, and egg masses parasitised by T viride, compared to their individual applications.
