Determination of effective doses and time of application of nematicides and castor leaves for controlling Meloidogyne javanica in tomato

Proper dose and time of application of aldicarb, carbofuran and chopped castor leaves were determined to control Meloidogyne javanica in tomato. Both the nematicides, at the rate of 2 kg a.i/ha, applied at transplanting, and chopped caster leaves, @ 40 and 60 g/kg soil, 7 days before transplanting, were effective. Application of aldicarb and carbofuran at transplanting and chopped castor leaves, one or two weeks before transplanting, significantly reduced number of galls and enhanced plant growth.
