Studies were carried out to evaluate the efficacy of various nematicides: aldicarb (Temik 10G), and carbofuran (Furadan 3G) at 3 kg a.i./ha, mocap (Ethoprop 10G) at 5 kg a.i./ha and oilcakes ofcastor ( Ricinus communis L., 4.2% N), groundnut ( Arachis hypogea L., 7% N), linseed ( Linum usitassimum L., 4.7% N), neem ( Azadirchta indica Juss, 5.4% N) and mustard ( Brassica compestris L., 4.8% N) at 1 g N/kg of soil in the form of soil amendments for the management of Meloidogyne incognita (Kofoid & White) Chitwood infesting Egyptian henbane ( Hyoscyamus muticus L.). All the treatments resulted in a significant increase in length, fresh and dry weights ofhenbane plants as compared with untreated inoculated plants. The maximum improvement in plant growth parameters was observed in plants treated with mocap followed by neem cake, aldicarb, carbofuran, castor, mustard, groundnut and linseed cakes respectively. Application of nematicides and oilcakes suppressed the pathogenic effect of M. incognita on Hyoscyamus muticus and resulted in significant reduction in gall intensity and population density ofroot-knotnematode in roots and soil. In comparison to untreated inoculated plants the highest reduction in root-knot index was noted in plants treated with mocap, whereas the lowest reduction was observed in plants treated with linseed cake.
