The International Transit Centre, which holds the largest in vitro collection of Musa cultivars and species, only distributes plant material that has been certified free of pathogens and diseases. Andrew Geering, a plant pathologist at the Department of Primary Industries and Fisheries in Australia, argues that it should make an exception for material infected with banana streak viruses, as long as approval is granted by the relevant plant protection authority in the importing country. Pierre-Yves Teycheney, a virologist at the French Agricultural Research Centre for International Development CIRAD argues that there is not enough information to make an informed decision.
