Situation of Phytophthora ramorum in Slovenia

In Slovenia, Phytophthora ramorum (EPPO A2 List) was found for the first time in 2003 (EPPO RS 2003/161). Official surveys then detected the pathogen in central Slovenia, 3 times in public parks (2004, 2005, 2009) and once in a nursery in 2007. These findings were linked to the introduction of infected plant material, and all were successfully eradicated. During the 2016 survey, P. ramorum was found on Rhododendron sp. plants in a public park. Symptoms of shoot dieback and leaf spot were observed. Infected plants and potential host plants within a radius of 2 m around infected plants were destroyed. In 2017, P. ramorum was still present in the soil where infected plants had been grown. Tracing-back studies showed that infected plants had been imported.

The pest status of Phytophthora ramorum in Slovenia is officially declared as: Transient: actionable, under eradication.
