EPPO-listed plant pests were assessed and ranked according to the overall risk they pose to Norwegian plant health. Based on probability of entry, probability of establishment (including spread), and potential impact on plant health, pests were classified into five risk classes: very high, high, moderate, low, and very low risk. 

In this first progress report VKM has assessed 61 pests: 24 fungi, 12, nematodes, 11 insects, eight viruses, and six bacteria. None of these were assessed to pose very high risk, while one pest (Fusarium euwallaceae) was assessed to pose high risk. Six pests were assessed to pose moderate risk: Dendroctonus ponderosae, Tuta absoluta, Phymatotrichopsis omnivora, Verticillium dahliae hop strains, Xanthomonas euvesicatoria pv. euvesicatoria, and Xanthomonas euvesicatoria pv. perforans. The remaining pests were assessed to pose low risk (16 pests) or very low risk (38 pests) to Norwegian plant health.
