Abstract
Leaching of fluroxypyr-MHE in an oil palm agroecosystem was conducted for two seasons; the dry and wet season. The oil palm estate is situated in central Selangor Peninsular Malaysia at an altitude of 70 m to 100 m above sea level. The study plot covered six ha and consisted of nine subplots of 0.66 ha each. The nine subplots received three treatments namely; the manufacturers recommended dosage (T1) double the manufacturers recommended dosage (T2) and the control (T3) with no herbicide treatment. Each treatment was done in triplicate each subplot was separated by a two meter buffer zone. The herbicide fluroxypyr-MHE (Starane 200 EC; Dow Elanco Ltd.) was applied as an aqueous spray using a knapsack sprayer at a spraying volume of 250 L/ha. Soil samples collected at different depths (viz. 0-10 10-20 20-30 30-40 and 40-50 cm) and at the following intervals -1 (before treatment) 1 3 7 14 30 and 60 days after treatment. Fluroxypyr-MHE was observed at all depths (0-50 cm) for the wet season when applied at the recommended and doubles the recommended dosages. Meanwhile for the dry season fluroxypyr-MHE was detected in the soil up to 1 and 5 days after treatment when applied at the recommended and double the recommended dosages respectively.
