The aim of this study was to compare organic and integrated pest management systems in terms of the influence of the application of specific pesticides on the elemental composition of grapes and wine. Samples of wine and grapes were obtained from an experimental vineyard estate running both viticulture systems. A comparison of agricultural techniques was carried out under identical climatic and soil conditions. Another important aspect of this study was the comparison in the 2019 season with high fungal disease pressure in the South Moravian Region, which forced the winegrower to use limited doses of protective agents, mainly based on Cu. The work focuses on the determination of 15 elements (Na, Mg, Al, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Pb) in soil, grapes and wine selected according to plant nutrition, toxicology and human diet. Elemental analysis of samples was carried out by inductively coupled plasma mass spectrometry (ICP-Q-MS). Differences in the elemental composition of samples from organic and IPM production were observed in all types of tested samples. The most fundamental differences were found in the case of Cu. Due to the higher application dose of copper fungicides in organic vineyard, the concentration of copper in organic wine (Sauvignon blanc) was almost 3 times as high (774 ± 35 μg.l-1) as in wines from IPM (259 ± 27 μg.l-1). This study also demonstrated a direct effect of mancozeb application in IPM on elevated Zn an Mn levels in grapes and wine. However, none of the investigated elements exceeded the limits set by national, European or OIV regulations for wine.
