Leaching behaviour of halosulfuron-methyl in sandy loam soil


Author(s): Ritu Devi, Anil Duhan and Satbir Singh Punia

Abstract: Halosulfuron-methyl is a new frequently used sulfonylurea herbicide however there is lack of published information on its leaching potential in soil. The mobility of halosulfuron-methyl at two application rates 50 and 100 µg in sandy loam soil was studied under laboratory conditions. Residues of halosulfuron-methyl in soil and leachate were estimated by HPLC-QDA. Under continuous as well as discontinuous flow conditions with stimulated rainfall of 300 mm, the movement of halosulfuron-methyl was observed throughout the column. Percent retention of halosulfuron-methyl was found to be maximum from 25-30 cm under continuous flow condition and maximum retention of halosulfuron-methyl was from 15-25 cm under discontinuous flow condition. Results obtained by the study revealed that halosulfuron-methyl was highly mobile in soil column. A comparable retention of halosulfuron-methyl residues at both doses was observed. Leachate fraction also contains halosulfuron-methyl residues.
