We assessed different extraction parameters, looking for maximizing extraction efficiency. The enhanced percolation technique showed an efficient extraction process, facilitated using bioethanol as a solvent at room temperature. We carried out field trials to check the efficacy of the extract. We observed a decreased severity and incidence of powdery mildew after application of the extract, and a reduction in the infestation of B. occidentalis. These results highlight the potential of this extract as a sustainable alternative to chemical biocides. © 2024 Instituto Nacional de Investigación Agropecuaria / Universidad de la República.
