Causal agents of Stemphylium-induced foliar diseases of tomatoes and other Solanaceae hosts in Brazil.

Aim: An extensive survey was done to clarify the prevalent Stemphylium species on Solanaceae plants across Brazil, and their host ranges.

Methods And Results: Eighty nine (89) Stemphylium isolates were obtained from naturally infected tomatoes as well as S. paniculatum, potato, eggplant, scarlet eggplant (Solanum aethiopicum var.

Diversity of species associated with torch ginger anthracnose.

Anthracnose caused by species is one of the most important diseases of torch ginger. The disease leads to loss of aesthetic and commercial value of torch ginger stems. This study aimed to characterize species associated with torch ginger anthracnose in the production areas of Pernambuco and Ceará.

Elucidating the Colletotrichum spp. diversity responsible for papaya anthracnose in Brazil.

Papaya (Carica papaya L.) is among the most important tropical fruits produced in Brazil and is grown in nearly every state. However, several diseases can affect papaya production.

causing stunting and malformation of sunflower plants in Brazil.

Sunflower (Helianthus annuus L.) is among the main oleaginous crops used in Brazil. During January, 2017, at CCA/UFPB laboratory and greenhouses (Areia/Brazil, 6°58'12″ S; 35°42'15″ W), we observed various sunflower seeds (cultivar Olisun 3, 2017-2018 crop) highly infested with Fusarium.

Occurrence of causing anthracnose on .

Cassava () is one of the main food sources of energy in developing countries owing to its starch-rich roots (Pinweha et al., 2015). Anthracnose is considered the most destructive disease of the aerial part of this crop (Bragança et al.

First report of causing anthracnose in cassava in Brazil.

Cassava (Manihot esculenta Crantz) presents significant economic importance in Brazil and other developing countries due to its use in human and animal feeding. In 2019, cassava plants sampled in Pará state (Brazil) presented necrotic and irregular leaf spots, characteristic symptoms of cassava anthracnose. About 90% of the plants were symptomatic, and disease severity was higher during months with high temperature and humidity.

First report of Colletotrichum chrysophillum causing cassava anthracnose in Brazil.

Cassava (Manihot esculenta Crantz) has significant socioeconomic relevance in Brazil and other developing countries, as one of the main sources of carbohydrates for human and animal consumption (De Oliviera et al., 2011). Among the cassava crop diseases, anthracnose is one of the main limiting factors for production and may be caused by species like Colletotrichum plurivorum, C.

Optimal markers for the identification of Colletotrichum species.

Colletotrichum is among the most important genera of fungal plant pathogens. Molecular phylogenetic studies over the last decade have resulted in a much better understanding of the evolutionary relationships and species boundaries within the genus. There are now approximately 200 species accepted, most of which are distributed among 13 species complexes.
