ANALYSIS OF PHYTOSANITARY MANAGEMENT IN BORDÔ VINEYARDS IN ORGANIC AND CONVENTIONAL PRODUCTION SYSTEM IN RIO GRANDE DO SUL
viticulture; organic production; profitability.
Viticulture is an important activity in Brazilian fruit growing, with Serra Gaúcha being the largest producing region. Organic viticulture in Brazil is small and primarily driven by family farming, while globally it is expanding. However, the insufficiency of scientific research on production systems and the scarcity of organic production technologies impact farmers. The aim of this study was to analyze the phytosanitary management of Bordô grapes in the 2021/2022 and 2022/2023 harvests, comparing organic and conventional systems among producers from the Cooperativa Agroindustrial Nova Aliança in the state of Rio Grande do Sul, examining indicators such as productivity, quality, and profitability. The analyzed results reported that the conventional system was more intensive in terms of frequency and number of products applied and achieved higher gross profitability and productivity in both harvests. In contrast, the organic system had lower theoretical costs and fewer phytosanitary applications but with lower gross profitability. The analysis suggested that a balance between organic and conventional practices could optimize efficiency and profitability. Additionally, it highlighted the lack of correlation between quality and profitability, indicating the need to review pricing policies.
