Resumo: | The effects of different types and concentrations of alternative products were evaluated for thecontrol of late blight of tomato in organic production. Citric acids, algae, bordeaux mixture, microorganismsolutions, vegetable extracts and silicates were tested in three experiments under field conditions at the Southern Coast of Santa Catarina. The disease was quantified by the area under the disease progress curve (AUDPC) and progress rate (r). The total and commercial yields were also determined. Experiments were conducted in completelyrandomized design with four replications. Treatments were compared with Scott-Knott test (P < 0,05). Bordeaux mixture 0,5% reduced AUDPC by 67%, 35% and 49%, as well as disease progress rate were 50%, 16% and 30% compared with control in spring 2004, spring 2005 and autumn 2006, respectively. The yield was affected by the season of the year and Bordeaux mixture yielded 114% more compared to other treatments. None of the alternativeproducts influenced the yield and the control of the late blight of tomato. |

Avaliaram-se diferentes tipos e concentrações de produtos alternativos comparados com calda bordalesa no manejo da requeima do tomateiro sob cultivo orgânico. Ácidos cítricos, algas, calda bordalesa, extratos vegetais, compostos de microrganismos e silicatos foram testados em três experimentos sob condições de campo. A doença foi quantificada pela determinação de sua área abaixo da curva de progresso (AACPD) e taxa de progresso (“r”). Determinou-se a produtividade total e comercial de frutos dos diversos tratamentos, utilizando-se a cultivar de tomate Santa Clara. Os tratamentos foram comparados pelo teste de Scott-Knott (P < 0,05). A calda bordalesa 0,5% proporcionou reduções significativas de 67%, 35% e 49% da AACPD, assim como 50%, 16% e 30% da taxa “r” nos plantios de primavera 2004 e 2005 e outono-inverno/2006, respectivamente. O efeito da calda bordalesa 0,5% na produtividade variou conforme a época de plantio, alcançando produtividades superiores de até 114% em relação aos outros tratamentos. Nenhum dos produtos alternativos foi eficiente no manejo da doença e no aumento da produtividade.
