| Abstract | ||
| The effect of root dip-treatment with aqueous leaf extracts of pomegranate. Punica granatum; olive, Olea euroba; castor. Ricinus communis; Mango, Manfjfera indica and peach. Prunus persica either alone or integrated with Oxamyl were carried out under greenhouse conditions to compare their effectiveness against R. raniformis infecting tomato CN. Strain-B3 as well as plant growth response. Results illustrated that most treatments proved to be more effective in improving tomato plant growth to certain extent, exceeded that of nematode alone (2.63). R. communis Integrated with Oxamyl treatment proved to be the best in promoting the fresh weight of the whole plant followed by R. communis alone, P. granatum + Oxamyl and then M. indica plus Oxamyl treatment. Their percentages of increase were 63.56 %. 63.14 %, 55.08 % and 54.66 %, respectively. All treatments showed significant reduction in total number of reniform nematode in soil and roots of tomato with rate of nematode build-up ranged from 0.180 for Oxamyl to 0.256 for P. persica. Egg-masses numbers of R. reniformis on tomato plant were significantly reduced in all treatments as compared with nematode alone. | ||
