Laboratory experiments were conducted to evaluate the effect of Tomatine on subterranean termites, nematodes and soil borne pathogens. At 12 HAT (Hours After Treatment) Chlorpyriphos 1000 ppm recorded the highest mortality (100 %) of subterranean termite, Odontotermes wallonensis followed by Tomatine 1000 ppm (99.00 % mortality). Cent percent mortality of Meloidogyne incognita juveniles (j2) was observed in Tomatine (1 g / lit) at 36 HAT. Tomatine 1.0 g / lit recorded nil percent hatching of eggs upto 30 HAT. The same treatment recorded the lowest egg hatching of 1.45 percent at 36 HAT. Lowest mean mycelial growth of soil borne pathogens, Sclerotium rolfsii (5.10 %), Fusarium solani (4.00%) and Pythium aphanidermatum (5.60%) was recorded in Tomatine 1.0 % treatment
