This work consists of an inventory of plant-parasitic nematodes which  can be dependent on the 
date  palm  For  the  three  cultivars  (Adala,  Timjouhert  and  Ghars)  at  the  two  depths  (35cm  and 
60cm) at two periods (December and March ) in the three farms ( EL-Atteuf, N'tissa, boulila) in 
the Ghardaïa region. The nematological analysis showed the presence of 187 individuals of plant-parasitic  nematodes,  revealing  17  genera  of  nematodes belonging  to  11  families with  a 
dominance of Pratylenchidae , Longidoridae , Anguinidae , are classified belonging to two orders 
( Tylenchyda and Dorylaimida )  the  physical  characteristics -chemical  characteristics  of  the 
sampled  soils  (sandy  texture  and  medium  to  low  organic  matter  content)  are  favorable  for 
nematode activity. And for the analysis of the phytopathogenic mycoflora we allowed 9 species 
 
59 
 
to  be  phytopathogenic  : Verticillium  sp, botrytis  sp,  trichodorma  sp,  Fusarium  oxysporum  , 
Fusarium solani , Fusarium sp, Aspergillus sp, Verticillium dahlia and Altirnaria sp. , the plant-parasitic nematode - phytopathogenic fungus complex of the date palm present by plant-parasitic 
nematodes such as ( Meloidogyne sp ) with the mushroom complex ( Fusarium oxysporum ) from 
the date palm.
