Importance and distribution

Species of Kabatina are parasitic and take nutrients and growth-regulating substances from the plant (Thambugala et al. 2014). There are six Kabatina species in Index fungorum, but one species has been synonymized and transferred to Dothiora as D. mahoniae. Kabatina thujae var. juniperi has been synonymized to Kabatina juniperi. Kabatina comprises four species known on Abies grandis (Pinaceae), Calocedrus decurrens (on foliage (Cupressaceae), Chamaecyparis lawsoniana (Cupressaceae), Chamaecyparis nootkatensis var. pendula (Cupressaceae), Juniperus sp. (Cupressaceae), J. virginiana, Mahonia repens (Berberidaceae), Olea europaea (Oleaceae) and Thuja plicata (on foliage.) (Cupressaceae). Kabatina has a wide geographical distribution such as Asia (Japan), Europe (Balearic Islands, Germany, Netherlands), New Zealand, North America (Canada, the United States (Nebraska))

 

Quarantine significance

Kabatina is of quarantine concern as it is the causal agent of Kabatina blight which results in dieback to death of terminal branch ends of junipers, cypress, and arborvitae in North America and Europe (Thrush et al. 2021).
