Field experiments were conducted thrice during at Tamil Nadu Agricultural University on a Sandy clay loam soil to study the bioefficacy of dazomet in tomato nursery. Application of dazomet at 60g m⁻² effectively controlled the root knot nematode Meloidgyne incognita and the weed species Echinochloa colonum, Trianthema portulacastrum, Gynondropsis pentaphylla and Dactyloctenium aegyptium. The dehydrogenase activity of the soil was also significantly affected by the application of dazomet; however the population was slowly building up at five days after dazomet application. Dazomet 30 g m⁻² was also effective against root knot nematode and weeds, although to a lesser extent than 60 g m⁻² and was significantly superior to control.
