Effect of chopped leaves and namaticides on the interaction of Glomus Fasciculatum with Meloidogyne Incognita on cowpea

The experiment on the effect of different chopped leaves and nematicides on the interaction between Glomus fasciculatum and Meloidogyne incognita was laid out in earthern pots on cowpea in glasshouse. Among the chopped plant leaves, Prosopis juliflora gave the highest growth of the plants followed by Catharanthus roseus, Leucaena leucocephala, Calotropis procera and Azadirachta indica. The chopped leaves gave better biomass production than the chemical treatment, but the chemical treatment recorded high reduction in the namatode population. Among the nematicides, phorate (10G) was more effective than carbohran (3G). The chopped leaves increased the VAM spore production and colonization and reduced nematode population.
