Chondrostereum purpureum is a fungal wound pathogen of trees and shrubs and its potential as an effective biological control agent to suppress undesirable hardwood trees in forest renewal sites has been established. To commercialize C. purpureum, under the trade name "ECOclearâ„¢", registration efforts by the Canadian Forest Service and Mycologic Inc. are underway. Under the North American Free trade Agreement, the guidelines for registration of naturally occurring microbial pest control agents are presently being harmonized between regulatory bodies in Canada and the USA, namely the PMRA and the EPA, respectively. The guidelines include the following data requirements for registration of microbial control agents: agent characterization and specification, manufacturing methods and quality control, human health and safety testing, food and feed residue studies, environmental fate and toxicology, and efficacy. The implications of these guidelines to research will be discussed. The C. purpureum project has progressed to the pre-commercial stage of development and is poised to become North America's first mycoherbicide for forest vegetation management. This model may set a precedence for the development of future microbial control agents for use in forest areas.
