Efficacy of nematicidal seed treatment in the control of root-knot nematode, Meloidogyne incognita on mungbean Vigna radiata
Abstract
The efficacy of seed treatment with three nematicides viz., aldicarb sulphone, carbofuran and thimet @ 1, 2 and 3 per cent a.i. (w/w) was studied for mungbean in 4 sq.m field plots infested with Meloidogyne incognita at initial density of 5 second stage juveniles per cc of soil. Aldicarb sulphone @ 1 per cent was found to be most effective in increasing grain yield. Aldicarb sulphone at 2 and 3 per cent and carbofuran and thimet at 3 per cent did cause marked reduction in nematode population but failed to cause proportionate increase in yield due to phytotoxic effects and decreased germination percentage.
