Sensibilidade de isolados de Cercospora coffeicola a azoxistrob
Summa Phytopathologica, 2022 O Brasil é o maior produtor mundial de café (Coffea arabica L.) e o segundo maior mercado consumidor. Dentre os fatores bióticos que acometem a produção do cafeeiro, cita-se a ocorrência da cercosporiose, doença cujo agente etiológico é o fungo Cercospora coffeicola Berk. & Cooke) (1).

Quinoa Saponins, Biological Controller Against Cercospora coffeicola and Moniliophthora roreri
Horticulture International Journal, 2021 An extract rich in saponins obtained from quinoa residues showed in vitro anti-fungal activity against the coffee phytopathogen Cercospora coffeicola, with an antifungal index of inhibition (AI) of 22.39 ± 4.5% at 120 mg/mL, and against the cocoa phytopathogen Moniliophthora roreri, with an AI of 55.8 ± 1.6% at 60 mg/mL.

Quantification of cercosporin from coffee leaves infected by Cercospora coffeicola
Australasian Plant Pathology, 2022Cercosporin, a nonspecific toxin produced by Cercospora spp., Pseudocercosporella spp. and Colletotrichum spp., is a photosensitizing compound that rapidly kills plant cells in the presence of light. Although this toxin is a virulence factor, its quantification in coffee leaves has not previously been reported.

Cercospora coffeicola is the causal agent of brown eye spot, an important disease of coffee (Coffea arabica) in Brazil. However, atypical symptom as darker and larger lesions, named black spot, has been reported in field. In this study, we tested the hypothesis that the causal agent of black spot belongs to the same species pathogenic to brown eye spot.

Temperature, incubation time and virulence of Cercospora coffeicola in the production of cercosporin
Journal of Phytopathology, 2019AbstractThis study considers the influence of temperature, incubation time and virulence in the production of the toxin cercosporin by Cercospora coffeicola, the causal agent of brown eye spot in coffee. The area under the progress curve of cercosporin production (AUPCCP) was also evaluated.
