Notes:No serious diseases of concern were observed on the NZ native plants apart from some leaf spotting and mottling similar to that observed in NZ. However we were very surprised at the aggressive mollusc and slug attack on the Carmichealia and Plantago. Both animals may be of concern to native plants if they were to become established. Arion lusitanicus is a large animal and has moved through Europe reasonably rapidly. A pest risk assessment for MAF Biosecurity by a mollusc specialist may be appropriate. Virus-like symptoms were observed on Phytolacca americanum (pokeweed) with yellow leaf ring spotting and Scopolia carniolica (Scopolia) with chlorotic chevrons and leaf ring spotting. Both plants were growing in the systematic collection and Dr Frank Rabenstein is to diagnose these at BAZ. A further comment on the susceptibly of NZ native plants overseas: It seems that in N America Gaultheria depressa is susceptible to Colletotrichum gloeosporiodes and researchers at BAZ need material from NZ in order to try and raise disease resistant crosses.
