Greenhouse as well as micro plot (or t door) experiments on the efficacy of
certain plant oil extracts i.e. garlic 1 %, sesame 5 Yo and Egyptian lupine 1 % or sesame
oil cake applied singly and/or mixed with oxamyl for controlling Me/oidogyne incognita
infecting sunflower c.v. Iroflora revealed tha all treatments improved sunflower
grow1h, and reduced root galling. Sesame either at 5% or oil cake singly achieved the
highest values of percentages of increase for v; hole plant fresh weight and shoot dry
weight that were accounted to 40.0% and 31.6% for greenhouse plants: and 24.17
and 32.4% for micro-plot ones, respectively. Concomitant treatments. using any plant
oil extracts tested or sesame oil cake integrated with oxamyl showed better increase
of plant grow1h parameters than those of oxamyl alone. Sesame 2.5% plus oxamyl at recommended (half dose) application
surpassed other plant oil extracts applied sing y or with oxamyl in suppressing of
juveniles (J2) number per 250 g soil as well 3S nematode galls with percentage
reduction of 91.9 and SO.7%, respectively. Moreover, great suppression in number )f nematode galls per root system of
sunflower was recorded with sesame oil cake nixed with ox amyl (74.3%) for micro-
plot plants. Obviously, seed weighVhead, weight of 100 seeds and seed oil
percentage were significantly increase in micro-plots receiving concomitant treatment
with values of 75.0, 160.91 and 22.S% as compared with single application,
respectively.
