Studies on avoidable losses in mung bean (Vigna radiata) due to root-knot nematode, Meloidogyne javanica and its control under field conditions

In mung bean (Vigna radiata) avoidable losses under field conditions due to Meloidogyne javanica ranged from 42.1 to 93.4 per cent by use of carbofuran applied @ 1.2 and 4 kg a. i./ha. Out of 34 genotypes screened for resistance to M. javanica, none exhibited resistant response. Control of M. javanica by seed treatment alone, soil treatment alone, or a combination of both practices showed that the yield per plot and plant height were maximum when seed treatment with carbosulfan (Posse 25 ST) @, 1% a.i. (w/w) + soil application with phorate (Thimet 10G) @ 1.0 kg a.i./ha were combined.
