“…Notes : This fungus was commonly known as the causal agent of grapevine anthracnose [or grapevine spot anthracnose – as recommended by Jenkins (1947)], which appeared to be of European origin and causes heavy losses in various grape-growing countries throughout the world, requiring chemical control – particularly where grapes are grown under humid conditions (de Bary, 1874, Shear, 1929, Amorim and Kuniyuki, 2005, Poolsawat et al., 2010, Carisse and Morissette-Thomas, 2013). de Bary (1874) described this species as Sphaceloma ampelinum , and Shear (1929) described the sexual morph as Elsinoë ampelina , having hyaline, 3-septate ascospores, 15–16 × 4–4.5 μm.…”

Species of Elsinoë are phytopathogens causing scab and spot anthracnose on many plants, including some economically important crops such as avocado, citrus, grapevines, and ornamentals such as poinsettias, field crops and woody hosts. Disease symptoms are often easily recognisable, and referred to as signature-bearing diseases, for the cork-like appearance of older infected tissues with scab-like appearance. In some Elsinoë-host associations the resulting symptoms are better described as spot anthracnose. Additionally the infected plants may also show mild to severe distortions of infected organs. Isolation of Elsinoë in pure culture can be very challenging and examination of specimens collected in the field is often frustrating because of the lack of fertile structures. Current criteria for species recognition and host specificity in Elsinoë are unclear due to overlapping morphological characteristics, and the lack of molecular and pathogenicity data. In the present study we revised the taxonomy of Elsinoë based on DNA sequence and morphological data derived from 119 isolates, representing 67 host genera from 17 countries, including 64 ex-type cultures. Combined analyses of ITS, LSU, rpb2 and TEF1-α DNA sequence data were used to reconstruct the backbone phylogeny of the genus Elsinoë. Based on the single nomenclature for fungi, 26 new combinations are proposed in Elsinoë for species that were originally described in Sphaceloma. A total of 13 species are epitypified with notes on their taxonomy and phylogeny. A further eight new species are introduced, leading to a total of 75 Elsinoë species supported by molecular data in the present study. For the most part species of Elsinoë appear to be host specific, although the majority of the species treated are known only from a few isolates, and further collections and pathogenicity studies will be required to reconfirm this conclusion.

RESUMOAs doenças fúngicas são um dos principais problemas de interesse econômico na viticultura, devido às grandes perdas registradas. Neste sentido, o objetivo deste trabalho foi testar o óleo essencial de alecrim (Rosmarinus officinalis), no controle da antracnose e do míldio da videira. As concentrações de 0, 500, 1000, 2000 e 4000 µL L -1 desse óleo essencial foram utilizadas nos seguintes experimentos: crescimento micelial e esporulação de Elsinoe ampelina, germinação de esporângios de Plasmopara viticola e a avaliação da severidade da antracnose e do míldio da videira a campo. Observou-se que a concentração de 4000 µL L -1 de óleo essencial, reduziu em 21% o crescimento micelial de E. ampelina, porém nenhum dos tratamentos apresentou diferença estatística para esporulação desse patógeno. Para a germinação de P. viticola não houve diferença entre os tratamentos. Em condições de campo, verificou-se que a concentração de 4000 µL L -1 , proporcionou redução de aproximadamente 91% da Área Abaixo da Curva do Progresso da Doença (AACPD) da antracnose da videira. Porém para o míldio, não foi relatada diferença estatística. Dessa maneira, a concentração de 4000 µL L -1 de óleo essencial de alecrim, foi eficiente no controle direto sobre E. ampelina, tanto in vitro quanto em campo, mostrando ter grande potencial no manejo integrado de doenças. Palavras-chave: controle alternativo; Rosmarinus officinalis; Vitis vinifera Essential oil of rosemary in the control of the diseases of the vine cultivar Cabernet Sauvignon ABSTRACTFungal diseases are one of the main problems of economic interest in viticulture due to the great losses recorded this sense. The purpose of this work was to test the essential oil of Rosemary (Rosmarinus officinalis), without control of anthracnose and of the downy mildew of the vine. The concentrations of 0, 500, 1000, 2000 and 4000 μL L -1 of essential oil were used for the following experiments: mycelial growth and sporulation of Elsinoe ampelina, germination of sporangium Plasmopara viticola and the evaluation of the severity of anthracnose and downy mildew from the field. It was observed that a concentration of 4000 μL L -1 of essential oil, reduced 21% the mycelial growth of E. ampelina, none of the treatments has presented statistic difference for sporulation of this pathogen. For a germination of P. viticola there was not difference between the treatments. Under field conditions, it was found that a concentration of 4000 μL L -1 provided a reduction of about 91% of the Area Under the Disease Progress Curve (AUDPC) of anthracnose of the vine. However, for mildew, no statistical difference was reported. Thus, a concentration of 4000 μL L -1 of essential oil of rosemary was efficient with direct control over E. ampelina, as wel in vitro as in the field, showing great potential with integrated management of diseases.

“…Disease initially appears during sprouting, phase propitious to the anthracnose establishment because the young leaves are highly susceptible (Brook 1973;Carisse and Morissette-Thomas 2013). During this study the first symptoms appeared on the leaves sprouted and later on petioles and tendrils, all the leaves petioles with symptoms and all tendrils between two leaves with symptoms also presented symptoms, showing that the leaves tissues are more susceptible than the petiole and tendril tissues and, therefore, presented the symptoms first.…”

“…However, while, in the study of Brook (1973), the leaves showed susceptibility to infection only while they were young and still growing, in this study the leaves were susceptible to anthracnose infection not only while they were young, but when they were old too, but the older had lower susceptibility. Other study in Canada showed that younger leaves (less than 5 days old) are more affected by anthracnose and the disease tolerance increase when leaves age increased 1 day (Carisse and Morissette-Thomas 2013). Similarly, in Jundiai, Sao Paulo State, vineyards of Niagara Rosada the first symptoms of anthracnose appeared during the month of October associated with consecutive days with precipitation over 10 mm of rain (Fiorine 2006).…”

Anthracnose is a severe disease present in several grape production areas; it is considered a tropical disease. In South Brazil, high relative humidity and other conditions favor the occurrence of fungal disease in vineyards. The objective of this study was to evaluate the anthracnose incidence progress in grape leaves in three scion cultivars (Concord, Bordô and BRS Carmem) in combination with three rootstock (1103 Paulsen, VR 043-43 and IAC 766), in regional climatic conditions favorable for disease development. The experiments were carried out on ridges with semi-trellis system. The experimental design was randomized blocks, with split plots, with 4 replications and 4 plants per plot. The plots were represented by 9 different combinations. Disease incidence was assessed at two week-. At each sampling, disease was assessed 10 leaves of a same shoot of 6 plants for each cultivar/rootstock combination, for a total of 54 plants. All cultivar-rootstock combinations showed disease symptoms with highest disease incidence coinciding with the greatest amount of precipitation. Based on the relative area under the disease progress curve (AUDPC), the anthracnose incidence showed differences between seasons. Differences between rootstocks and rootstock/cultivar combinations were observed during the first and third season, but there was no consistency between the seasons, indicating that the variation in disease progress could be due to other factors, including as weather conditions, age of the vineyard and inoculum pressure.
