Leaching potential of oxyfluorfen in soil Tandon Shishir*,1 1G.B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand, 263 145 *Email: shishir_tandon@lycos.com
Abstract Leaching potential of oxyfluorfen herbicide was evaluated in clay loam soil under laboratory conditions with simulated rainfall. Oxyfluorfen was applied at 240 and 480 g/ha on 60 cm long soil columns. Oxyfluorfen leached upto 10 cm soil depth but, maximum concentration (84.5%) of the total herbicide applied was observed on upper top soil. Residues were not detected in leachates. Study indicates low mobility of oxyfluorfen in clay loam soils under saturated moisture conditions and may not pose ground water contamination problem if not used indiscriminately.
