Results of isolated fungi from seedlings of three Strawberry varieties Sweet Charlie, Hapil and Festival showed that the root zone in the three varieties contained the largest number of fungi. The fungus F. culmorum was the highest existence in three areas roots and runners and crown. The isolation percentage was 66.15% in the runners zone of Hapil and 36.15 % in the root of Sweet Charlie, while the existence percentage of the fungus above was 55.76% in the crown area and 35.79% in the root zone of Festival, while the fungi Cylindrocarpon spp. appeared at 38.60 % in runners of sweet charlie and 35.91% in the root of Hapil, while fungus isolated from Festival in 23.60% in root zone, and the lowest rate was in fungus A. alternata in the root of sweet charlie with 2.32% and the fungus Phytophthora spp. in Hapil. In Festival fungi St. herbarum appeared lowest ratio 3.47 % in the root, the different percentages for the isolation of the fungi differed with the differentiation of varieties studies of Strawberry plant and isolation areas. The testing biological agent Trichoderma harzianum Indicates that his high efficiency against fungi F. culmorum and Cylindrocarpon spp. and Bipolaris spp. its degree antagonistic to 2, 2 and 2 respectively. Inhibition percentage was 88.88% and 87.77 % and 86%, respectively, for three fungi. For ability of bacterial biological agent Pseudomonas aeruginosa showed significant inhibition to the growth of three fungi. The study of the bacterial biological agent and fungus Cylindrocarpon spp. showed significant inhibition as well as bacterial biological agent and fungus Bipolaris spp. with inhibition percentage 100% Finally the results showed that the fungicides Azadirachtin in concentration 5cm 3 /liter inhibited significantly the growth of three fungi, and the highest percentage inhibition was with the treatment of fungicides and fungi Cylindrocarpon spp. with inhibition percentage 80 % while the lowest percentage of inhibition was 21.87% in Fungi F. culmorum.
Quantitative estimation of growth regulators results Indol Acetic acid (IAA) and Gibberellic acid (GA 3) using technology high performance liquid chromatography (HPLC) in strawberry plants (variety Hapil and Festival) treated with three fungi Fusarium culmorum, Cylindrocarpon spp. and Bipolaris spp.The results varied depending on the variation of ments, as the level of the growth regulators IAA and GA 3 increased in fungal biocontrol Trichoderma harzianum and bacterial biocontrol Pseudomonas aerogenosa and chemocontrol Azadarachtin, compared with the nontreatment plants infected with three fungi above, the highest concentration of the growth regulator IAA was 921.81 ng/g wet weight in plants treatmed with fungal biocontrol and less concentration in the plants treated with fungus F. culmorum alone, the level was 10.20 ng/g wet weight in strawberry variety Hapil while Festival variety was the highest concentration of plant growth regulator in fungal biocontrol and less level was in the treatment with Cylindrocarpon spp. the concentrations in the rest of the transactions between the two in both varieties. The concentration of the growth regulator GA 3 differed with the differentiation of the concentration of the growth regulator IAA in strawberry variety Hapil and Festival and all the transactions studied, the highest concentration of it in strawberry variety Hapil were treated bacterial biocontrol, the level was 341.97 ng / g wet weight while the level in strawberry variety Festival is 897.62 ng / g wet weight in plants treatmed with fungal biocontrol while the less level of the growth regulator GA 3 in strawberry variety Hapil and Festival was 30.29 ng / g wet weight and 20.34 ng / g wet weight in the treatment with the fungus Cylindrocarpon spp. alone, the concentrations in other treatments ranged between the two in both varieties.
