Abstract
Neem cake, bacterial biocontrol agent, Pasteuria penerrans and fungal biocontrol agent, Paecilomyces lilacinur were evaluated either singly or in combination (at half the dose) for the management of root-knot nematode, Meluidogyne incognita infecting tomato under nursery and main field conditions. Integration of all the three components gave maximumincrease in plant growth parameters and number of seedlings per bed. Parasitism of Mincognita females was maximum when neem cake was integrated with Rpenetranr, while egg parasitism was highest when neem cake was integrated with P. lilacinur. Under field conditions, planting of tomato seedlings (raised in nursery beds amended with neem cake + R penetrans) in pits incorporated with R lilacinus at 0.5 g inoculum per plant gave least root galling and nematode multiplication rate. The above treatment was also effective in increasing fruit weight and yield of tomato
