Tebuconazole residues were determined on grapes treated with minimal and maximal recommended concentrations. The grapes samples were collected randomly after 1, 5, 10, 15 days after last application, extracted using the ethyl acetate method, and finally analyzed with a gas chromatograph instrument. The method was validated, and performance criteria complied with legislation requirements. Recovery data was over 90%, the limit of quantification Limit of Quantification was smaller than maximum residue limit and linearity ? 20%. According to the maximum residue limit, the degradation of Tebuconazole for the recommended concentrations applied dissipated between 10 and 15 after the last treatment.
