Abstract:

Coffee is one of the most popular non-alcoholic beverages consumed all over the world. The coffee industry offers lively hood for millions of people directly and indirectly among the coffee growing countries. The coffee crop is known to be affected by many diseases at different seasons. Earlier, the pathogen Myrothecium was known to cause stem necrosis and leaf spot disease on coffee seedlings in the nursery. In the recent years, there was a gradual increase in the incidence of leaf spot and fruit rot of Arabica coffee caused by Myrothecium in the field condition during rainy season. During the visit to coffee plantations in Chikkamagaluru and Hassan districts, the plants and weeds growing in and around the coffee plantation were observed for the presence of leaf spot with typical symptoms caused by Myrothecium. A total of eleven different plant species viz., Colocasia sp., Alternanthera bettzickiana, Remusatia vivipara, Phlebodium aureum, Alternanthera brasiliana, Polypodium triseriale, Urtica sp., Artocarpus heterophyllus, Tarenna asiatica, Impatiens dasysperma and Hibiscus rosa-sinensis with typical symptoms of Myrothecium were identified. Based on the morphological character the fungal cultures were identified as Myrothecium roridum. The development of typical symptoms of Myrothecium on the Arabica coffee leaves cross-inoculated with pure fungal culture indicated the cross infecting ability of the fungus isolated from different host plants. As per our knowledge this is the first report indicating the cross infecting ability of the Myrothecium roridum cultures on Arabica coffee leaves isolated from different host plants, majority of them were weed plants commonly grown in and around coffee plantation.
