Abstract
Leaching potential of metsulfuron-methyl herbicide was evaluated under laboratory conditions in Mollisol soil of Pantnagar, Uttarakhand with simulated rainfall. Metsulfuron- methyl was applied at recommended dose (4 g/ha) on 60 cm long soil columns. After seven days of experiment, maximum concentration was observed in 30-35 cm column depth and some amount of herbicide leached out and was detected in leachates. Study indicated high mobility of metsulfuron-methyl under saturated moisture conditions which may pose significant ground water contamination.
