Myrtle rust was first detected in New Caledonia in Farino in the south province on Syzygium jambos in March 2013 and has been confirmed in April 2013. The fungus disease was subsequently confirmed in the north and in the east coast of the country. It is not known how Myrtle rust entered New Caledonia. Rust fungi produce microscopic spores which are carried by wind, people’s clothing, plants or goods that are shipped around the world. A decision was taken that eradication of the disease was not technically feasible due to the establishment of the fungus in many distant places from each other. Nevertheless actions of surveillance and punctual control continue to be led.
