Etude de l’effet de la poudre de quelques organes du palmier dattier (pennes, cornefs, lif, graine) sur nématodes phytopathogènes

Abstract

The possibility of controlling phytopathogènes nematodes has been tested using dental palm organ powders. The powder of three cultivars (Deglet Noure, Ghars and Tafsouine). The results show that the nematodes behave differently to the organ powders used (penne, lif, cornf, seeds (nucleus).) These data show that the corrected mortality rate increases with increasing concentrations of d The tests carried out to treat nematodes in the cultivated soil of radish, penny powders, lif, cornf and nuclei of Deklet Nour and Tafzouin which are the most effective in giving a high mortality of nematodes. The correlated mortalities obtained in the two treatments (in the aqueous medium and at the level of the cultivated soil) are very close. The organs of Deglt Nours (pennes 73%, lif 93% cornef 50%, nuclei 90.3% after 2 days). Tafzouin organs (pena 70%, lif 80%, cornf 50%, nuclei 89%) with respect to the organs of Ghars (pennes 40%, lif 60%, cornf 22% and nuclei 87%).
