Studies were conducted during May 1984 on estimation of losses in okra under field conditions naturally infested withMeloidogyne javanica.The yield of okra was reduced at population levels of 296 ± 5Meloidogyne javanicalarvae per 250 g soil. Percentage avoidable losses in yield ranged from 20.2 to 41.2% by using carbofuran and aldicarb at 2.0 and 4.0 kg. a.i./ha respectively. Aldicarb gave better results than carbofuran at both the doses. Cost‐benefit ratio was found maximum (1:11.7) with aldicarb at 2.0 kg a.i./ha whereas it was minimum (1:1–8) in carbofuran treated plots at 4.0 kg a.i./ha.
