| Sumario: | The aim of evaluating electrolysed oxidising water (EOW)for controlling botrytis (Botrytis cinerea), powdery mildew(Sphaerotheca pannosa) and downy mildew (Peronosporasparsa) using two greenhouse rose varieties was to verifythis new technology’s effectiveness by contrast with traditionalchemical handling. Two concentrations of hypochlorousacid in EOW were produced during electrolysisin aP1200 cell and applied at three application volumesusing stationary hydraulic pressure equipment. Thecommercial rose varieties (Rosa sp) used here were theOrlando and Versilia varieties. The EOW used was slightlyacidic type C, pH 5.0, having high-oxide-reduction potential(ORP) +850 millivolts (mV). Two types of EOWwere evaluated for this study: EOW C-50 (50 ppm HOCl)and EOW C-75 (75 ppm HOCl). The test results showedthe feasibility of EOW as a fungicide at the volumes testedhere, providing significant control of powdery mildewwhich has high incidence due to climatic conditions. Thebest disease control was achieved by applying the highestvolume; however, some curled leaflets appeared with thisapplication. |
