“…Six Fusarium species common to coffee as saprophytes or true pathogen (Hakiza and Webesa, 1997;Serani, 2000) namely F. xylarioides, F. solani, F. oxysporum, F. decemcellulare, Fusarium Palldoroseum, and F. Lateritium identified according to Nirenberg (1976) and Booth, (1971) were used to identify the target antigen in this study. Soluble proteins, crude cell component, fungal homogenate, culture fluids, and ribosomal proteins from fungal pathogens have been used to raise antibodies (Jamaux and Spire, 1994; Priestley and Dever, 1993; Srivastava and Arora, 1997). In this study, part of the soluble mycelial extract was used as the antigen for antibody production.…”
