DISSIPATION OF FLUROXYPYR IN A MALAYSIAN AGRICULTURAL SOIL WITH SIMULATION USING THE PERSIST AND VARLEACH MODEL

Author(s): HALIMAH, M*; SULAIMAN, N*; ISMAIL, B S** and TAYEB, M A**

The study was carried out to compare the dissipation of fluroxypyr in a Malaysian agricultural soil based on field experimentation and simulation using the PERSIST and VARLEACH model. A plot situated in an oil palm plantation near Sepang, Selangor, Malaysia was selected for the field experiment. The plot was treated with fluroxypyr at the recommended dosage (72.5 g ha-1). The soil samples from the field trial were collected and analyses conducted in the laboratory according to the sampling schedule. Simulation of fluroxypyr persistence and leaching was also conducted using computer-run software, PERSIST and VARLEACH. The predicted data obtained using PERSIST for fluroxypyr was found to be higher than the observed data from field measurements. However, the predicted data for fluroxypyr using VARLEACH matched well with the observed data from the field trial.
