TAILIEUCHUNG - first report on cross-infection of coffee leaf spot pathogen Myrothecium Roridum on black pepper

Myrothecium roridum, a fungal plant pathogen is known to infect the leaves and stem of coffee seedlings in the nursery and leaves and berries of the plants in the field. The pathogen has a very wide host base infecting many agricultural and horticulture crops, ornamentals, gymnosperms and weeds. As black pepper is a major intercrop grown in the coffee plantations, the present study was under taken to test the ability of M. roridum to infect black pepper (Piper nigrum L.). Two isolates of M. roridum, isolated both from coffee nursery and field was inoculated on the leaves of pepper vines. The results indicated that the coffee isolates of M. roridum could infect the leaves of the pepper vines. Two days after of inoculation, the pathogen expressed the symptoms on the inoculated leaves of pepper vines similar to that of Myrothecium leaf spot observed on coffee. The sporodochia could be observed on the inoculated pepper leaves on both lower and upper surface 8 days after inoculation and were arranged concentrically on the affected area. The artificial inoculation confirmed the ability of the pathogen M. roridum existing on coffee can infect the pepper vines and cause crop loss. As per our knowledge this is the first report of M. roridum found pathogenic on pepper vines. | first report on cross-infection of coffee leaf spot pathogen Myrothecium Roridum on black pepper
