Laboratory experiment was conducted to understand the persistence behavior of tetraconazole in three soils of West Bengal (alluvial, red lateritic, and coastal saline) and also in water maintained at three different pH (4.0, 7.0, and 9.2) conditions. Processed soil samples (100 g) were spiked at two treatment doses: 2.5 μg/g (T1) and 5.0 μg/g (T2). Double distilled buffered water (200 ml) was spiked at two treatment doses: 1.0 μg/ml (T1) and 2.00 μg/ml (T2). The tetraconazole dissipation followed first-order reaction kinetics and the residual half-life (T 1/2) values in soil were found to be in the range of 66.9–77.2 days for T1 and 73.4–86.0 days for T2. The persistence increased in the order red lateritic > new alluvial > coastal saline. Interestingly, the red lateritic soil exhibited the lowest pH (5.56) and organic carbon (0.52 %) content as compared to other two soils. However, the dissipation of tetraconazole in case of water was not pH dependant. The T 1/2 values in water were in the range of 94 to 125 days. The study indicated the persistent nature of tetraconazole in soil and water.
