The aim of this study was to evaluate the efficiency of alternative products to control downy mildewand anthracnose in grapevine. An experiment was carried out at Epagri/Urussanga Experiment Station, in Santa Catarina State, Brazil, from September 2004 to February 2005. The following treatments were tested: Fitophos
K®, Phosphorus K®, Ecolife-40®, Bordeaux mixture, extract of the alga Ulva fasciata and control. All treatments reduced leaf downy mildew severity compared to non-treated plants (24,7%). However, the highest disease
reduction was reached by spraying Ulva-extract, which did not differ significantly from both Bordeaux mixture and Ecolife-40® treatments. Plants treated with alga extract had lower anthracnose incidence in grape bunches
(15%) than the control (42,5%), but did not differ from those treated with Phosphorus K®, Bordeaux mixture and Fitophos K®.
