| Abstract | ||
| This study is aimed at the effect of t types of bacteria Azotobacter chroococcum & Bacillus thuringiansis in protection of sour orang seedlings from F.s that causes root rot of citrus trees in babil governorate the result of this test show the infection ability of fusarium isolated ; the isolated varied in their effect in germination percentage of cabbage seeds .the germinetien percent varied from 0 – 4 % which it wan 100% in the control treatment (without infection ) . on the other hand , the results reflects the feasibility of the experiment factors A. chroococcum and B. thuringiansis . under the lathhous conditions as well as the pultary manner in reducing the infection intensity of (Fs.1) for one – year old citrus seedling , that it cause reduction up to 8.27% and 9.5 % infection intensity . this however caused an increment in growth characters (fresh weight , dry weight , plant height and root length for 16.20 26.50 , &gm/plan 4.60, 10.00, t cm/plant 86.30,51.70 respectively as compared with the control treatment (the fungi com ) which recorded 30. 70 10.33, 19.80 , 50.10 & gm/plant 10.80, 5.00 , cm/plant respectively | ||
