The present study was undertaken to determine the persistence and residue of oxyfluorfen in tea and sandy clay loam acid soil with a pH of 4.3 and organic carbon content of 4.1%. Results showed that, the application of oxyfluorfen at 200 g /ha persisted in soil up to 10 days while up to 25 days at 400 g/ha and 50 per cent degraded from the soil before 30 days. Within 3 hrs of application, 6.9 to 35.8% of the oxyfluorfen dissipated from the soil. More than 80% of the applied oxyfluorfen degraded from soil before 10 days of its application under 200 g/ha, while it took 25 days at 400 g/ha. Oxyfluorfen residue was not detected in tea leaves upto 50 days. It is concluded that the waiting period of 75 days should be implemented for plucking the tea leaves after the application of oxyfluorfen or else there will be a chances for the herbicide to enter the food chain due to bioma-gnification.
