Inadvertently introduced plant pathogens that infect invasive species might be effective weed biological control agents if developed for redistribution or augmentation of naturally occurring populations. Colletotrichum shisoi is likely an inadvertent introduction to the United States where it causes disease on perilla mint (Perilla frutescens). This study reports development and application C. as a agent. The effects dew period infection probability inoculum concentration biomass production were determined identify threshold dose required activity. Under controlled conditions, pathogen reduced biomass, flower production, interspecific competitive ability. In replicated field trial, both populations caused high mortality moderate changes in community composition over one growing season. Additionally, series experiments performed evaluate methods preservation spores. Overall, was found antagonist when applied inundatively under appropriate conditions. It may possible produce mass across invaded range North America, but further research needed adequate during transport application.
