Abstract
In this research four plants i.e. Moringa (Moringa oleifera), Cabbage (Brassica
aleracea), Cassia (Cassia nodosa) and Chinaberry (Melia azedaroch) were mixed, at
three levels 1, 2 and 4% of soil weight to manag root-knot nematodes, Meloidogyne
spp. under greenhouse conditions. Results revealed that chapped leaves of the four
evaluated plants significantly, reduced all related nematode parameters i.e. number
of galls, egg masses, females and developmental stages / root system, eggs / egg
mass and number of juveniles / 250 g soil, in comparing with nematode alone. The
highest significant reduction in galls, egg masses and J2 / 250 g soil (93, 92.8 and
89.6%, respectively) obtained with moringa at 4% of soil weight, followed by
cabbage chapped leaves at 4% (90.8, 88.9 and 85.8%, respectively), whereas the
lowest one observed with cassia chapped leaves at 1%. Generally, the effective
dose was 4% regardless the plant species and the effective plant was moringa
regardless the rate significantly enhanced all vegetative plant growth parameters i.e.
fresh shoot and root weight (g), dry shoot weight (g), plant height and root length (g).
Results showed also all treatments significant increase antioxidant enzymes activity
i.e. peroxidase and phenoloxidase, total sugars, total phenols and proline
concentration. Membrane leakage showed also highly significant decrease with all
treatment compared with the plant treated with nematode alone.
