Abstract

Fire blight was detected for the first time in Norway in 1986. It was a limited outbreak on the West Coast, only on ornamentals, particularly on Cotoneaster. An organization for the eradication and containment of fire blight was quickly established, and given comprehensive statutory powers and government resources to do surveys and eradicate diseased plants and highly susceptible plants from contaminated areas. The work has managed to restrict fire blight to the West Coast. Eastern and Northern parts of the country are considered pest free areas. The disease has not moved into important fruit-growing areas. Spread of fire blight to new areas has mainly been due to uncontrolled movement of beehives. From 1969 to 2016 import of all host plants from countries with fire blight has been prohibited. Systematic yearly surveys by foot and car in all parts of the country, using digital maps, internet connected tablets with GPS, and software for registrations made in the field have proved to be an efficient tool to spot new outbreaks at an early stage and start eradication, thus limiting further spread.
