Laboratory experiments have showed the virulent ability of the R.solani and the percent of the decayed seeds reached to 57% in PDA media.When examining the effect of pathogenic fungus in the percentage of germination in the soil of pots and growth indicators there was a decrease in the percentage of germination was 74% compared with the control treatment 96% as well as the pathogenic fungus has led to a decline in the dry weight of shoot and root and height.The pots experiment in the greenhouse showed that the three irrigation amounts 50, 100 and 150 ml (water stress) have no effect on the percentages of seeds germination which were72.92and 71.25 and 70.83%, respectively, but they effected on the growth indicators (leaf area , stem diameter , plant height and number of leaves) .for leaf area was the highest area of paper rate in the irrigation level of 150 ml, amounting to 70.62 cm2 while gave the irrigation 50 level ml less leaf area amounted to 16.45 cm2 As for stem diameter the highest rate recorded in the level of 100 and 150 ml for irrigation, reaching 0.46 and 0.43 cm respectively, while the lowest rate at the record level of 50 ml for irrigation reaching 0.28 cm2The results showed also that there are significant differences for the rates of plant height between the level of 50 ml for irrigation, and levels of 100 and 150 ml who were very close in as the rate of plant height to them, 13.74 and 13.91 cm amounted respectively, while plant height rate at level 50 ml for irrigation dropped to 10.85 cm . and also there were significant differences in the average number of leaves of the plant between the irrigation water levels which gave the irrigation level of 150 ml highest rate of the number was 3.54 with significant differences and clear all levels of 100 and 50 ml, which was the average number 2.13 and 2.33 respectively . but there were no differences morale among the treatments in the case of R. solani or no to the previous growth indicators to plant maize .The study also showed ,in pots experiment in the greenhouse, when using three levels of Glomus mosseae (2.5, 5 and 7.5) gm Pot have had the same impact on growth indicators of maize plant and all those levels effected on the activity of pathogenic fungus R.solani . and inhibiteded by its impact on the plant.
