Effect of different plant products on the hatching of Meloidogy ne incognita eggs

The nematicidal properties of fifteen plant products viz., leaves of Albiuia amara, Aristalochia bractiata, Tagetes erecta, T. patula, Origanum majorana, Azadirachta indica, Butea monosperma and Calotropis gigantea, roots of Acorus calamus, bulbs of Allium sativum, seeds of Citrullus lanatus, Areca catechu and Anona reticulata, latex of C. gigantea and Carica papaya were screened against root-knot nematode, Meloidogyne incognita for egg hatch. The seed extract of Areca catechu recorded the highest inhibition rate at 0.1% concentration. Latex of Carica papaya caused 98.22 and cent per cent inhibition of hatching at 1.0 and 10.0% concentrations respectively. Latex of C. gigantea also caused cent per cent inhibition at 10.0% concentration.
