Abstract: Colletotrichum gloeosporioides is one of the most important pathogens of subtropical crops in South Africa. Limited control of the pathogen has been achieved with preharvest copper oxychloride and postharvest prochloraz treatments. Biological control agents, viz., Bacillus subtilis or B. licheniformis, have been shown to control anthracnose effectively by using preharvest field sprays or postharvest applications. Inconsistent levels of disease control have been recorded over the years and the research focus has shifted to improved biocontrol product formulation. Mode of action has been studied and diffusible metabolites which were found to impede growth of C. gloeosporioides, have been partially identified. Percentage spore germination was reduced significantly and bulb formation as well as lysis of hyphae were observed. In artificial inoculation studies, increasing concentrations of B. subtilis were effective against increasing concentrations of C. gloeosporioides. An integrated disease control program is currently being developed.
