Resumen

Phytophthora ramorum was found for the first time in Slovenia in 2003 and later once (2007) in a nursery and three times in public parks (2004, 2005, 2009) in close proximity of introduced infected plants. All above mentioned outbreaks were successfully eradicated which was confirmed by intensive sampling of plants, soil and water in infested areas.

During the survey of Phytophthora ramorum in 2016, the disease was found on plants of Rhododendron sp. in a public park. Symptoms of shoot dieback and leaf spot were observed. Infected plants and host plants in radius 2m around infected plants were destroyed. One year later P. ramorum was still present in the soil where infected plants had been grown. Tracing-back studies showed that infected plants were imported.

Pest has been regulated in Slovenia/European Union and EPPO (A2 list).
