Abstract: Residual fate and behaviour of the herbicide haloxyfop in onion leaf, soil and bulb were studied at the Horticultural Research Farm, B.C.K.V., West Bengal, India, (2001-2002) following application @ 100, 200 and 400 g a.i ha -1. Haloxyfop residue was derivatized by butylation before GLC analysis. Dissipation of haloxyfop in onion leaf and soil followed first order kinetics. The OT 50 values in onion leaf ranged from 3.24-6.71 days whereas 3.78-6.96 days for soil. No residue could be detected in bulb at harvest irrespective of doses.
