In this field experiments, sandy loam soil was treated with different concentration of herbicide (Quizalofop-ethyl) 0.5, 1.0, 1.5 and 2 per cent. Sesbania sesban L. seeds were sown in all treated soil. The germination percentage, morphological and enzymes activities were measured after 20, 40 and 120 days. The results indicate that the germination per cent, morphological parameters were increased in control then it was gradually decreased with increasing the herbicide concentration. The enzymes like catalase and peroxidase activity were increased in control then it was decreased with increasing the concentration. Whereas the polyphenoloxidase acticity was lower in control and it was increased with increasing the herbicides concentration. Hence, after 120 days plants were harvested and the plant powder was analyzed for absorption of herbicide by plant with the help of Gas chromatography mass spectrum (GCMS). The obtained data showed that herbicide absorption was concerned in quiazalofop-ethyl treated plant when compared to control. This study expose that herbicide reduced by Sesbania sesban L.
