Fenitrothion - Organophosphate insecticide is a cheap and widely used Insecticide throughout worldwide since 1959 and play an important role in modern farming and food production. It is commonly used in Paddy, Cotton, Fruits and Vegetables for controlling beetles, borers, fruit flies, foliar-feeding larvae, nematodes. Fenitrothion is dangerous to all living ecosystem, Excessive exposure to Fenitrothion effect the brain and peripheral nervous system of humans. Fenitrothion is an Acetylcholinesterase inhibitor and Carcinogenic. Fenitrothion with complex structure has high persistence in ecosystem and biosphere. The target aim of this study is to eliminate FEN residues from contaminated sites specifically in Paddy soils with Fungi. Isolate the Fenitrothion degraded fungi by the Screening process and check the potential degradation levels in both solid & liquid media’s and here the potential isolate uses phosphate as an energy source, examine the fungi under the microscope. The Pure fungi are subject for Molecular characterization with 26S rDNA gene sequencing and phylogenetic analysis and identified as Aspergillus parasiticus.
