Comparative Studies on the Nematicidal Properties of Typhonium Trilobatum and Melia Azedarach

Corm powder of Typhonium trilobatum and seed dust of Melia azedarach were tested in pot soil against Meloidogyne incognita to compare their nematicidal activity. T. trilobatum not only exhibited potentiality as nematicide than M. azedarach but acted as a better growth promoter also. In preplant application, T. trilobatum at highest dose controlled 18 per cent more nematode than that of M. azedarach while in residual toxicity test, it was 34 per cent higher when compared with M. azedarach.
