| Abstract | ||
| Two types of pesticides were selected as organic matter for their negative influence on human health and aquatic life. Two aquatic fungi Saprolegnia parasitica, Achlya sp. were used to examine their ability to degradation the insecticide Diazinon and herbicide Glyphosate with initial concentrations 50, 60, 70, 80, 90 and 100 ppm in water, of laboratory conditions of 20 Co and pH 7.2-7.6 in batch culture system for 6 days treatment period. Saprolegnia parasitica showed high capability to reduce Diazinon concentrations by 66.6%, 62.3%, 43.7%, 34.1%, 23.8% and Glyphosate concentrations by 75.4%, 61.8%, 47.8%, 37.5% and 30.5%.While, Achlya sp. showed lower ability to reduce Glyphosate concentrations by 62.2%, 52.3%, 42.4%, 32%, 23% and Diazinon concentrations by 43.2%, 39.3%, 25.1%, 24.6% and 21.8%. This study proved that aquatic fungi Saprolegnia parasitica, Achlya sp. have no ability to survive in pesticides concentration of 100 ppm. | ||
