Integrated control of head blight in wheat caused by the Fusarium graminearum in the Laboratory

          The results showed that the most common isolates of the Fusarium spp. in these samples is F.graminearum. It is one of the main pathogen that caused wheat head blight. The results of the experiment showed the effect of different variations and their interactions in Pots contaminated with the pathogen in the wheat variety Ibaa 99, where The highest yield was recorded in the Trichoderma viride, Penicillium commune,  Pseudomonas fluorescens Pf-DS  and fungicide( PcTvPfB) , which reached 70 g, compared to the pathogen treatment , which reached  to 6.00 g. The same treatments were also completely successful, completing 5.00 tiller/plant compared to the control treatment specified for the pathogenic fungus, which amounted to 0.67 tiller /plant. The lowest severity of infection appeared in treatment ( PcTvPfB)  when recorded at 30.67% with compared to the pathogen treatment  of 95%, followed by the treatments PcTvB, PcPfB, and TvPfB, where 48.66, 52.33, and 53.00 g . respectively, and the number of tiller/plant was 3.67, 4, and 4.33 tiller/plant, and the infection severity reached to  37.00, 42.67 and 43.33% respectively.
