| A four-year field trial was run to determine the effectiveness of copper fungicides and foliar fertilizers in controlling lettuce downy mildew (Bremia lactucae Regel) in Italy’s Emilia-Romagna Region. The experimental design was randomized blocks with 4 replicates using the highly susceptible Camaro cultivar. Eleven different fungicide formulae and foliar fertilizers with low copper concentration were compared. Tribasic copper sulphate (Cuproxat S.D.I.), copper sulphate (Poltiglia Caffaro 20) and copper oxychloride (Pasta Caffaro Nc) exhibited the best control; the effects of pentahydrate sulphate (Kay Tee) and hydroxyde (Kocide 2000) were less consistent. Hydroxide sulphate (Poltiglia disperses), tribasic sulphate (Cuproxat liquido) and the Special Kopper... |

| The aim of this study was to evaluate the efficacy of old and new copper formulations to control downy mildew Plasmopara viticola (Berk. et Curtis) Berl. et. De Toni). Field trials were carried out over the years 2002, 2004 and 2005 in a grapevine growing area in the Po Valley with a high disease pressure. Among the traditional copper formulations, hydroxide-based products gave the best results. Other new copper formulations, including foliar fertilizers, simple adjuvants and resistance inducers were evaluated. In particular, resistance inducers with a low percentage of copper gave promising results even though some of them show some phytotoxic problems. |
