In recent years, due to the ever-increasing population, the supply of quality food has become a major concern worldwide. Phytopathogenic fungi cause severe damage to crops worldwide and thus significantly reduce the quality and quantity of agricultural products. On the other hand, reducing the use of chemical pesticides in agriculture is a global goal. Meanwhile, different biological control methods, strategies and approaches are used in the management of plant diseases. Biological control is one of these critical techniques that is currently in priority. Biological control is an environmentally friendly and effective way to reduce the effects of plant diseases. In fact, the rhizosphere of plants supports the development and activity of a large and diverse community of microbial organisms, including plant growth promoting organisms. That these organisms can be used in the biological control of plant diseases. Fungi can be mentioned among these growth enhancing factors. Antagonists of fungi play an important role in the control of pathogenic and plant diseases and are used as biological control agents (BCAs) worldwide. These biological agents use various mechanisms such as activating defense reactions, antibiosis, plant growth stimulation, antibiotic production, and increasing the absorption of nutrients to control plant diseases. Finally, it can be said that the use of these factors significantly reduces the use of chemical fertilizers and pesticides.

The study was conducted on Al-Khosur River basin passing through the city of Mosul from the waterfalls region to its confluence with Tigris River at the Old Bridge. Six sites were selected along the river. Water and sediment samples were collected from there. The study was carried out at the laboratories of Mosul University, through the period from September 2021 A.D. to May 2022 A.D. The concentrations of heavy metals (lead, cadmium and zinc), in water and sediment were measured quarterly. The results indicated that the heavy metals in the water had the highest concentrations in the fourth site in three elements Pb, Cd and Zn, which amounted to (0.64, 0.62 and 0.49) mg/L, respectively. This can be attributed to the bad quality of the civilian subtractions and estuaries discharged in the river which contain high concentration of heavy metals. The results also indicated high rates of heavy metals in the sediments at the fourth site as it reached the concentration of (3.18, 0.92 and 2.85) mg/kg, for Pb, Cd and Zn, respectively. The concentrations of heavy metals in the sediments increased four times for lead and zinc and two times for cadmium due to the increment in water and the contact period between water and sediment due to undecomposition for heavy metals.

Some of the physical and chemical properties of Al-Khosur river water were studied in the city of Mosul. Samples were collected seasonally from 6 sites distributed along the banks of the river and at a rate of 3 replicates per site. Samples were collected and then taken to the laboratory and tests were carried out. Tests included the temperature, pH, electrical conductivity were measured in the site. Turbidity, total alkalinity, chloride, sulfates and phosphates were measured in the Laboratory. The results of the study showed that the temperature values ranged between (10.23-25.86) Co and pH value ranged between (7.12-8.13), while the value of electrical conductivity ranged between (844-2425) μs/cm and the turbidity was with values ranging between (31.73-87.40) NTu. As for the values of total alkalinity, sulfates, chloride and phosphates, their ranges were (126.0-228.7), (74.1-147.8), (61.83-126.27) and (0.15-1.98) mg/l respectively. The variations in the values of water characteristics were due to the differences in locations and the human activities through the river.
