Abstract

The effect of humic acid against hatching, longevity and mortality of root knot nematode, Meloidogyne incognita was investigated. The study revealed that increase in concentration of the extract of humic acid inhibited egg hatch and caused mortality of second stage juvelines of Meloidogyne incognita by 93 per cent at 0.4 per cent concentration.
