Abstract

Organic materials such as neem oil smearing (1% w/w) of okra and soil amendment with Datura stramonium and Calotropis procera leaves 5% (contained alkaloids like Scopolamine/Hyocin) alone and in combination with kalisena (a commercial formulation of Aspergillus niger) bio-agent and biofertiliser, AN 27 SD egg parasitic and toxin producing facultative fungi and Trichoderma harzianum as seed treatment (1% w/w) against M incognita showed that Calotropis sp. and neem oil alone mitigated root knot galls by 62%. In combined application, reduction in nematode multiplication was not enhanced than the alone treatments. Neem oil, T. hazianum and Calotropis in combined application affected maximum galling by over 58%. While kalisena in the same combination was not so effective in reducing the number of galls. Plants growth such as shoot length, root and shoot weight was improved in treated soil.
