- This study evaluated the efficacy of the extracts of Ophiocordyceps sobolifera isolate Cod-NB1302 for the biological control of chili anthracnose disease caused by Colletotrichum capsici and C. gloeosporioides under pot conditions. Among the extracts, mycelial extract treatments provide the best reduction in disease severity. Interestingly, two bioactive constituents, adenosine and cordytropolone, from the mycelial extract, inhibited growth of the fungal pathogens. Moreover, these bioactive compounds had a synergistic effect against the fungal pathogens in a pot experiment. These results confirmed the disease suppressive activity of the mycelial extract.
