Ralstonia solanacearum race 3 biovar 2 detected in New Caledonia
The presence of Ralstonia solanacearum race 3 biovar 2 (EPPO A2 List) was recently detected in New Caledonia. The bacterium was found in imported seed potatoes which had been planted in La Foa and Bourail (Province Sud). An infection was suspected when cutting seed potatoes before sowing, and the identity of the bacterium was confirmed in mid-June 2015 by the ANSES plant health laboratory in Angers (FR). Eradication measures were ordered by the New Caledonian authorities. The relevant seed potato variety will be destroyed, and a survey will be done in order to destroy volunteer potato plants.
