Fate of Tebuconazole in Polish Mineral Soils – Results of Simulations with FOCUS PELMO

The degradation of tebuconazole in the majority of Polish mineral soils with low organic carbon content is slow, and its adsorption is especially low in subsoils. Therefore, the fate of tebuconazole in these soils cannot be predicted based on results of adsorption and degradation experiments carried...

For this reason, simulations of tebuconazole accumulation in Polish soils and its leaching to groundwater were carried out.
