Control of root knot nematode, Meloidogyne incognita by certain botanical soil amendments on eggplant [electronic resource].

Includes references.

Nine medicinal and aromatic plants viz., santonia, Artemisia cinae; neem, Azadirachta indica; calotropis, Calotropis procera; stramonium, Datura stramonium ;eucalyptus, Eucalyptus globulus; melia, Melia azedarach; hamd, Mesembryanthemum forsskalie; geranium, Pelargonium graveolens; schinus, Schinus terebinthifolius were evaluated as botanical organic soil amendments against root-knot nematode, Meloidogyne incognita activity in natural and sterilized soils on eggplant under greenhouse conditions. All of botanical organic amendments satisfactory reduced (pSO.01) the total number of galls, females and egg-laying females as well as the total number of nematodes in eggplant roots compared with non treated check. Pots receiving hamd. schinus and stramonium performed the best minimizing females number with percentage of redaction 97.9, 95.5 and 94.6% respectively in sterilized soil com paired with Mocap (99.1%). While, powder of geranium, neem, calotopis and eucalyptus had comparatively lower effects. In non sterilized soil the best reduction in galls number induced by nematode infection performed with santonia (9), hamd (13), and neem (30.5) compared with Mocap (7) and untreated check {700.0 galls).therefore, the best minimizing female number was recorded when pots received these materials. The best of the percentage of female reduction were 98.8, 98.6 and 97.8 for hamd, santonia and schinus respectively compared with Mocap (99.7). While, powder of calotopis, eucalyptus, neem and geranium had comparatively lower effects. In sterilized soil, nematodes multiplied greater on eggplant than in natural one. The plant growth of eggplant as measured by length of shoot and root and weight of fresh and dry shoot and number of leaves showed an improvement over healthy plant in some treatment. As results, there was a positive reaction, in most cases, between botanical soil amendments treatment and plant growth.
