Epicoccum nigrum pigments currently used in food. It produces a variety of pigments, ranging from darker oranges to yellows and greens. These pigments were synthesized by nonpathogenic strains of "E. nigrum". In Brazil, "E. nigrum" is used to support root growth and control sugarcane pathogens. It is a biocontrol antifungal agent active against brown rot in stone fruit, caused the species "Monilinia laxa" and "Monilinia fructigena". In contrast to these uses for "E. nigrum" metabolites, there has been an investigation into methods of controlling "E. nigrum" fungal colonies that have contaminated historic and cultural artifacts. The fungus was found to be quite
