- Abstract
Presence of herbicides residue in the soil not only damages the succeeding sensitive crops but also adversely affect human and animal health due to bioaccumulation of residues in crop produce. Thus an experiment was conducted to evaluate persistence of sulfosulfuron residues applied in wheat crop as post-emergence at 25, 50 and 100 g ai ha−1 application rates to control weeds. Residues were evaluated in surface and subsurface soil by HPLC using Photo diode array detector. Sulfosulfuron residues were dissipated rapidly in surface and subsurface soil at initial period. After150 days residues were found below 0.001 μg/g in soil samples collected from 25 to 50 g ha−1 treated plots. However, at 100 g ha−1 dose residues were not detected after 200 days in surface and subsurface soil.
