Title A name given to the resource Intensidade da cercosporiose da alface em cultivos convencionais e orgânicos em Pernambuco Intensity of Cercospora leaf spot of lettuce in conventional and organic farming systems in State of Pernambuco, Brazil Creator An entity primarily responsible for making the resource Andréa Maria André Gomes, Sami Jorge Michereff, Rosa de Lima Ramos Mariano, Viviane Jurema Lopes Borges Rodrigues Description An account of the resource Foram realizados levantamentos da intensidade da cercosporiose da alface, causada por Cercospora longissima, em 25 plantios manejados no sistema convencional e 25 no sistema orgânico, em dois períodos de plantio, janeiro-abril (I) e junho-setembro (II) de 2002, no estado de Pernambuco. A prevalência da doença foi elevada (> 88%) em todas as situações avaliadas. Nas áreas de cultivo convencional a severidade da cercosporiose variou de 0,0 a 16,9%, enquanto em cultivos orgânicos de 0,0 a 22,5%. Nos dois sistemas de cultivo a severidade da doença foi significativamente mais elevada no período I, quando a precipitação pluviométrica foi quase três vezes superior ao período II. No entanto, somente no período II foram constatadas diferenças significativas na severidade da doença entre os sistemas de cultivo, sendo superior no sistema orgânico. Não foram constatadas correlações significativas entre os níveis de severidade da cercosporiose nas áreas de plantio nos dois períodos avaliados, dentro de cada sistema de cultivo.Surveys of the intensity of cercospora leaf spot of lettuce caused by Cercospora longissima were performed in 25 conventional and 25 organic farming areas in 2 planting periods, January-April (I) and June-September (II) 2002, in State of Pernambuco (Brazil). Disease prevalence was high (> 88%) in all evaluated situations. Disease severity ranged from 0.0 to 16.9% in conventional farming areas and from 0.0 to 22.5% in organic farming areas. In both systems, disease severity was significantly higher in period I when precipitation was almost 3 times higher to that in period II. However, only in period II, significant differences in disease severity were found between farming systems, with high values in the organic system. There were no significant correlations among disease severity levels in the areas in both evaluated periods inside each farming system.
