Na gestão da cultura da vinha estão envolvidas diversas atividades com a finalidade de se obter uvas sãs para produção de vinho. Sendo a busca da sustentabilidade dos sistemas de produção um constante desafio, é fundamental e necessário otimizar as práticas agrícolas e encontrar novas soluções de futuro eficazes e eficientes que tenham um menor impacto no meio ambiente, mas que garantam também a viabilidade económica desses sistemas.
Neste trabalho, desenvolvido na Quinta do Monte Xisto (Vila Nova de Foz Côa), pretende-se compreender e analisar a duração das práticas culturais desenvolvidas ao longo do ciclo cultural da vinha, bem como avaliar novas soluções que possam ser potenciais alternativas ao combate de algumas doenças que afetam a cultura. As atividades foram realizadas em todas as parcelas da quinta, assim como a duração de execução das mesmas. Na parcela Norte Baixo foram aplicadas infusões de flor de castanheiro, esteva, eucalipto e casca de citrino e avaliado o seu potencial antifúngico contra as doenças do míldio (Plasmopara viticola) e do oídio (Uncinula necator) da videira. A incidência e a severidade das doenças foram avaliadas nas folhas e cachos das videiras selecionadas.
No ano vitícola de 2021/22 foi necessário um total de 4053 horas para a realização de todas as tarefas na área completa da quinta, sendo as mais exigentes a poda de inverno, a despampa e a vindima. A inclinação do terreno, o vigor das plantas e a casta influenciaram a duração das tarefas realizadas. Relativamente ao caso de estudo sobre a avaliação do potencial antifúngico de novos produtos, no ano vitícola em estudo não se observaram diferenças significativas entre as modalidades ensaiadas.

As the search for sustainable production systems is a constant challenge, it is essential and necessary to optimise agricultural practices and find new, effective and efficient solutions for the future that have less impact on the environment, but also guarantee the economic viability of these systems. The aim of this work, carried out at Quinta do Monte Xisto (Vila Nova de Foz Côa), is to understand and analyse the duration of the cultural practices carried out throughout the vineyard's cultural cycle, as well as to evaluate new solutions that could be potential alternatives for combating some of the diseases that affect the crop. The activities were carried out on all the plots on the estate, as well as the duration of their execution. In the Norte Baixo plot, infusions of chestnut blossom, cistus, eucalyptus and citrus peel were applied and their antifungal potential against the grapevine diseases downy mildew (Plasmopara viticola) and powdery mildew (Uncinula necator) was assessed. The incidence and severity of the diseases were assessed on the leaves and bunches of the selected vines. In the 2021/22 wine-growing year, a total of 4053 hours were needed to carry out all the tasks in the entire area of the estate, the most demanding of which winter pruning, removal of shoots and harvesting. The slope of the land, the vigour of the plants and the grape variety influenced the duration of the tasks carried out. Regarding the case study on the evaluation of the antifungal potential of new products, no significant differences were observed between the treatments in the viticultural year under study.
