Ability of Aspergillus flavus to degradation of herbicide Topik EC 100 (Clodinafop-propargyl)

Aspergillus flavus was isolated from the soil field cultivated with wheat crop (Triticum astevium L.), which treated Topik EC 100 (Clodinafop-propargyl) herbicide in Al-Fuhud city, southeast of Thi-Qar Governorate-Iraq. samples were collected at a depth (0-15) cm for period 17 weeks, and fungus by dilution method, pH, electrical conductivity, organic matter texture measured. results showed that dominant this study, where percentage appearance 86%. active ingredient Clodinafop-propargyl solid liquid media (Mineral salt medium). its ability to grow medium containing substance. could biodegrade ingredient. substances measured Fourier Transform Infrared spectroscopy Gas chromatography- mass spectroscopy, biodegradation concentration 0.01 ppm 80%.
