Abstract

Greenhouse as well as micro plot (out door) experiments on the efficacy of certain plant oil extracts i.e. garlic 1%, sesame 5% and Egyptian lupine 1% or sesame oil cake applied singly and/or mixed with oxamyl for controlling Meloidogyne incognita infecting sunflower c.v. Eurofloura revealed that all treatments improved sunflower growth, and reduced root galling. Sesame either at 5% or oil cake singly achieved the highest values of percentages of increase for whole plant fresh weight and shoot dry weight for greenhouse plants; and for micro­plot, respectively. Concomitant treatments using any plant oil extracts tested or sesame oil cake integrated with oxamyl showed better increase of plant growth parameters than those of oxamyl alone. Sesame 1.5% plus oxamyl at recommended (half dose) application surpassed other plant oil extracts applied singly or with oxamyl in suppressing of juveniles (J2) number per 250 g soil as well as nematode galls. Moreover, great suppression in number of nematode galls per root system of sunflower was recorded with sesame oil cake mixed with oxamyl for micro­plot plants. Obviously, seed weight/head, weight of 100 seeds and seed oil percentage were significantly increase in micro­plots receiving concomitant treatment with values of 75.2, 160.87 and 22.8% as compared with single application, respectively.
