ABSTRACT - The establishment of olive (Olea europaea) orchards in Brazil is increasing due to their economic potential and benefits to human health. However, a number of limiting factors need to be overcome, such as Olive Leaf Spot (OLS) occurrence, for olives to reach their full potential. OLS, which is caused by Fusicladium oleaginum, results in defoliation and a reduction in fruit production. This study aimed to develop a standard area diagram set (SAD) for the assessment of OLS severity under humid subtropical climate conditions. The SAD was developed with six levels of severity (1, 3, 6, 9, 12 and 15%) and OLS severity was validated by eight inexperienced raters. Using the SAD provided an increase in accuracy, precision and concordance, while also reducing the smallest difference detectable. The proposed SAD was adequate at estimating the OLS and could be a useful tool for use in epidemiological and phytopathometry studies, evaluation of control strategies and selection of resistant genotypes.

RESUMO - O cultivo da oliveira (Olea europaea) no Brasil é crescente devido seu potencial econômico e pelos benefícios que seus produtos oferecem à saúde humana, entretanto, alguns fatores limitantes precisam ser superados, como a ocorrência do repilo (OLS). O repilo, causado pelo fungo Fusicladium oleagineum, causa desfolha e redução da produção de azeitonas. O objetivo deste trabalho foi elaborar uma escala diagramática para auxiliar nas estimativas de severidade de repilo em oliveira em condição de clima subtropical úmido. A escala diagramática foi elaborada com 6 níveis (1, 3, 6, 9, 12 e 15%) e validada por 8 avaliadores inexperientes. Com o uso da escala houve aumento na acurácia, precisão e concordância, também redução do menor valor de severidade detectável. A escala proposta foi adequada para estimar a severidade de repilo em oliveira, podendo ser utilizada para estudos epidemiológicos, avaliação de estratégias de controle e seleção de genótipos resistentes.
