PERSISTENCE OF PRETILACHLOR, PENOXSULAM AND PYRAZOSULFURON HERBICIDES IN SOIL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 8
Abstract
An experiment was conducted during Kharif season of 2012-2013 at experimental farm of Directorate of Weed Science Research, Jabalpur. The treatments included application of various herbicides applied to paddy crop @ pretilachlor 750 g a.i. ha -1, penoxsulam 25 g a.i. ha-1, and pyrazosulfuron 25 g a.i. ha-1 and weedy and hand weeding. The study was aimed to evaluate the pattern of dissipation, persistence and residue in soil at harvest. As regarded to the observation on persistence residue and dissipation study reveals that higher content of residue was found in sample taken at initially as well as during growth period with an interval of 5 days exhibited successive depletion of herbicidal residue with progressive growth of the crop till harvest. HPLC method for detection for persistence residue and dissipation indicated that a first order kinetics was followed and the average half life values ranged for pretilachlor (750 g a.i. ha-1), penoxsulam (25 g a.i. ha-1), and pyrazosulfuron (25 g a.i. ha-1) were 15.06, 26.65 and 24.75 days respectively.
