Abstract

Pesticides that are used to control mold, grass, and pests on agricultural land are highly toxic pesticides. In vitro Study of biodegradation was performed to monitor the biodegradability of fungicides, herbicides, and pesticides using native taxa of Egyptian fungi isolated from sandy loam agricultural soils. Supplemented with Esfenvalerate, Tribenuro-methyl, and Actamiprid 20% SP 3 times and irrigated for 45 days. The effectiveness of organophosphate pesticides was evaluated on soil fungal populations. The results showed a clear difference in the number of fungi between no treatment (control) and pesticide treatment. When treating the soil; fungicides, herbicides, and pesticides; Fungicides revealed 19334 colonies, herbicides 19130, and pesticides 40572 total colonies. Control soil (untreated) showed a total of 16666 colonies.
Three types of fungi (Fusarium oxysporum, Aspergillus terreus, and Penicillium chrysogenum) isolated from soil treated with various pesticides were selected to evaluate their ability to degrade tested pesticides in laboratory conditions. Data show that (Aspergillus terreus) and (Fusarium oxysporum.) accelerated the decomposition rate of all pesticides mentioned in this study and had the greatest effect by comparing with Penicillium chrysogenum. Present study, help to develop suitable environmental strategy to remove pesticides from polluted environments.
