Abstract
A pot experiment was conducted to evaluate the influence of certain oil-seed cakes i.e. fennel, sesame, anise or plant dry seed powder of red pepper as soil amendments in comparison with oxamyl or urea on controlling Meloidogyne incognita infecting eggplant seedlings under greenhouse conditions at 27 ± 5°C. Results indicated that all tested materials significantly improved the growth of eggplant and suppressing the number of galls, females and egg masses of M. incognita as compared to nematode alone. Moreover, anise oil-cake gave the best growth of total plant fresh and dry shoot weights as percentage increase (160.8 and 64%) followed by sesame oil-cake (143.5 and 64%), respectively. However, the highest values of percentage reduction for number of galls (64.2%), females (58.5%) and egg masses (55.7%) on eggplant roots were achieved by sesame-oil-cake application, followed by anise-oil-cake treatment with values of 63.0, 59.6 and 51.1% for the same nematode criteria, respectively. Meanwhile, oxamyl or urea treatment showed remarkable reduction percentages for nematode parameters tested.
