Abstract<\/strong><\/p>\n\n\n\n

This research aimed to study several isolates of pathogenic fungi\ncausing root rot phenomenon on wheat and barley. Six fungal isolates of Rhizoctonia<\/em>,\nFusarium<\/em> and Helmenthosporium<\/em>, were used in this study. These\nisolates were treated with four chemical fungal disinfectants, in addition to\nfungus Trichoderma harzianum<\/em>. The laboratory experiment was achieved\nwith incubation the isolates within petri dishes at a temperature of 22 \u00b1 2 \u00b0C.\nThe diameters of fungal colonies above the culture medium were measured daily\nfor a period of six days. The pot experiments were achieved on durum wheat (Bohooth\n5) and barley (Tadmor) which were known with their sensitivity to the\ninfection. The germinated seeds were treated with the fungal disinfectants and\nthen they were planted in the pots within the incubator. After the formation of\nthe two first leaves, the experimental pots were subjected to the natural\nenvironmental conditions. The pots were watered and fertilized as needed.\nConcerning the laboratory dishes within the incubator, the results of\nstatistical analyses clarified that the treatment with fungicide Vetavax and\nthe fungus T. harzianum<\/em> were more performed. While, concerning the pot\nexterminates, the results showed that Vitavax was more effective in the\nreduction of the infection rates for both wheat and barley. Although the\nbeneficial fungus T. harzianum<\/em> had a limited efficacy, its efficacy was\nhigh in controlling the isolate R1 of the pathogen Rhizoctonia<\/em>. The\nobtained results lead to investigate the causes of the limited efficacy of Trichoderma<\/em>\nin the pot experiments.<\/p>\n\n\n\n
