Abstract
Cyhalofop-butyl is a recently registered herbicide from the aryloxyphenoxy propionate group in India to control a wide range of grass weed species at various growth stages in rice crop. Field experiment with rice variety Pusa Sugandh 5 was conducted at IARI, New Delhi. Rice crop was sprayed thrice with cyhalofopa-butyl at 40, 60 and 80 g ha−1 at the 10, 20 and 30 DAS. Harvest soil samples were extracted and analysed for cyhalofop-butyl and cyhalofop acid residues by HPLC using CH3OH:H2O (80:20) mobile phase at a flow rate of 1 mL min−1 at 240 nm wavelength using PDA detector. In harvest soil the residues were below the detectable limits.
