| Abstract A series of laboratory and field experiments to test the efficiency of the bacteria Bacillus circulans in controlling wheat root rot disease caused by Pythium aphanidermatum . The results showed that seed of wheat treated with B.circulans gave a high seed germination percentage reached 91.3% with the lowest number of seedling death of 5.1% for control treatment (wheat seed alone), which amounted to 80.3% and 12% respectively. The results of this experiment confirmed the ability of bacteria to provide high protection to plant wheat against the influence of P. aphanidermatum where treatment bacteria gave the highest percentage of germination of seeds of wheat planted wheat planted Petrb contaminated with pathogenic fungi, which amounted to 86% while the percentage of germination in the control treatment (62%) and the plant death percentage was at lowest level at same treatment which were 17.96% compare with control ( 58.03%) The results showed in significant increase in the growth indicators (plant height , tellaring number ,fresh weight and dry shoots and roots weight ) as well as production parameter including number and length of spike, grain / spike and weight of 1000 grains. | ||
