Abstract
The present study is a relative contribution to the study of the effect of powders of different date palm organs
(penins, seeds, horns and lif) of three cultivars (Ghars, DegletNour and Tafzouin) on phytopathogenic nematodes.
The results obtained show that the nematodes behave differently with respect to the applied treatments.
DegletNour and Tafzouin organ powders showed the best results. Indeed, mortality rates of 95% to 100% in 48
hours have been reported. Nuclei have the fastest and most effective toxic potency; a dose of 0.5g will be enough
to kill the nematodes. The larvae are the most sensitive and the males are the most resistant. Analysis of ANOVA
showed that the effect cultivars is significant, and the effect of doses not significant.
