“…Por otro lado, una fertilización con dosis altas de N, K y fósforo (P) reducen considerablemente la Cercosporiosis en hojas, y mantienen un mayor número de hojas y el balance nutricional en plantas de café (Vilela et al, 2022). El uso de abonos verdes intercalados con plantas de café también reduce la incidencia y el número de lesiones de Cercosporiosis en hojas, y la incidencia de pudrición en frutos, ambas enfermedades causadas por C. coffeicola, siendo su eficiencia similar a la mostrada por la aplicación de urea (Cardoso et al, 2013). Otras prácticas culturales que podrían reducir considerablemente la enfermedad en cafetos comerciales i.e.…”

Coffee (Coffea spp.) is the second most significant commodity worldwide, with C. arabica being its most representative species. The coffee crop is affected by different fungal diseases that reduce the photosynthetically active area of its leaves and the production of grains. In order of agronomic importance, the rust caused by the biotrophic pathogen Hemileia vastatrix is a disease difficult to manage due to its type of reproduction. Another no less important, Thread Blight, caused by the basidiomycetes Ceratobasidium noxium (Syn. Corticium koleroga) and C. chavesanum, affects all aerial tissues of plants. The third disease, Cercospora leaf spot caused by Cercospora coffeicola, affects both leaves and grains, making it difficult to manage. Although there is enough scientific information on Rust, very little is known about the etiology, symptomatology, life cycle, and management of Thread Blight and Cercospora leaf spot. High-resolution photographs and micrographs were used and related with available scientific information. In addition, current scientific information on each disease was compiled, and with that, the life cycles were developed. Likewise, this manuscript describes the management of the three diseases based mainly on the use of genetic, cultural, physical, biological, and chemical measures and their integration as a sustainable alternative in the coffee agroecosystem. Current and future challenges in coffee include the evaluation of cultivars, genetic diversity of Ceratobasidium spp. and C. coffeicola, plant-pathogen interactions, and agroecological management practices.

Assessment of crop loss due to multiple diseases and pests (D&P) is a necessary step in designing sustainable crop management systems. Understanding the drivers of D&P development and yield loss helps identify leverage points for crop health management. Crop loss assessment is also necessary for the quantification of D&P regulation service to identify promising systems where ecosystem service provision is optimized. In perennial crops, assessment of crop losses due to D&P is difficult, as injuries can affect yield over years. In coffee, one of the first perennials in which crop loss trials were implemented, crop losses concurrent with injuries were found to be approximately 50% lower than lagged losses that originated following the death of productive branches due to D&P. Crop losses can be assessed by field trials and surveys, where yield reduction factors such as the number of productive branches that have died are quantified, and by modeling, where damage mechanisms for each injury are considered over several years.

“…Under field conditions, Cercospora leaf spot is managed by routine copper based fungicide sprays; a contact fungicide which requires routine sprays which may lead to copper toxicity [18][19][20] . Several management tactics have been employed to manage the disease which include growing coffee under shade, fertilisation of coffee [21] , green manuring in combination with urea treatment [22] , were also found to be important in reducing the effects of the disease.…”

Cercospora leaf spot is fast turning into a critically important diseasein Zimbabwe. The disease is caused by Cercospora coffeicola whichsignificantly reduces productivity and quality of coffee. Disturbingly,optimum sporulation of Cercospora coffeicola in culture remains a limitingfactor for microbial analysis and quantitative studies of Cercosporaleaf spot. Faced with this challenge, an in-vitro study was conducted atCoffee Research Institute, Manicaland, Zimbabwe to examine growth ofCercospora coffeicola in different nutrient media and to determine the bestmedia for Cercospora coffeicola analysis. Six nutrient media were assessed(corn meal agar, oat meal agar, Czapek Dox agar, malt extract agar, yeastextract agar and potato dextrose agar) for the growth of Cercosporacoffeicola. The laboratory-based experiment was duplicated, laid out ina Completely Randomized Design, replicated three times and based onCercospora coffeicola nutrient inoculation. Data were collected on radialgrowth, colour and texture of mycelium at 3 and 6 days after inoculation.There were significant differences (p < 0.05) in the growth of Cercosporacoffeicola in media after 3 and 6 days. Malt extract agar had the greatestradial growth (34 mm and 32 mm) of Cercospora coffeicola for trials 1and 2 respectively, whilst the least growth was in the oat meal agar (14.2mm and 15.7 mm) for trials 1 and 2 respectively. There were variations incolour and texture of mycelium with malt extract agar, potato dextrose agarand oat meal agar associated with darker colours and rough texture whilesmooth white mycelia were found in corn meal agar. After considering allnutrient media, malt extract agar was found to be the best media for thegrowth of Cercospora coffeicola in-vitro. On the basis of our findings, theauthors recommend the use of malt extract agar as the primary media foridentification and characterisation of Cercospora coffeicola.
