- Abstract
This work aimed to evaluate the influence of soil characteristics and the applied amount of nicosulfuron on the degradation rate in soil. Soil samples were collected at three localities in Bosnia and Herzegovina -- Manjača, Kosjerovo and Tunjice. The experiment was carried out under controlled laboratory conditions. Plant protection product based on nicosulfuron (40 g a.s./L, OD) was applied in concentrations of 0.075, 0.15, and 0.30 mg a.s./kg of soil. Nicosulfuron residues were analysed by the modified QuEChERS method, followed by LC-MS/MS. Soils are classified as silty loams, with variations in mechanical composition and chemical properties. In slightly alkaline soil, the half-life (DT50) of nicosulfuron has increased (43.31 days) compared with DT50 (9.43-16.13 days) in acidic soils. The results indicate that soil characteristics and applied concentration significantly influence nicosulfuron persistence. Hence, it can be considered that nicosulfuron, applied to silty loam soils of Bosnia and Herzegovina, poses a low risk to subsequent crops and the environment.
