Ascochyta tarda Ascochyta tarda Ascochyta tarda or Phoma tarda is a fungal plant pathogen that causes dieback and leafspot on coffee and was first observed in Ethiopia in 1954 (Stewart, 1957). It poses a potentially serious threat to coffee crops, but climate change may reduce the prevalence of environmental conditions favorable to its spread. Die-back is a condition in which a tree or shrub begins to die from the tip of its leaves or roots backwards, owing to disease or an unfavorable environment). Necrosis of both flowers and rosettes is also observed with this pathogen and this can significantly reduce crop yield.
