Antagonistic activity of fungal flora isolated from pepper phylloplane on postharvest pathogens of pepper (Capsicum annuum).

Of the 29 different phylloplane microflora isolated from leaves, flowers and fruits of actively growing pepper (C. annuum), only three species of Trichoderma and Rhizopus strains were found to have antagonistic activities to Aspergillus niger, Rhizopus nigricans [R. stolonifer], Penicillum citrinum and Oidium sp., the postharvest pathogens isolated from rotted pepper fruit. The in vitro screening showed that the Trichoderma species had moderate to strong antagonistic activities to the postharvest pathogens by inhibiting their growth in culture. The result showed that the mode of antagonism was by nutrient competition, though observation in some cases showed mycoparasitism. Successful antagonism occurred when the antagonists were inoculated several hours before the pathogens.
