- ... Black foot disease, caused by Ilyonectria liriodendri and Dactylonectria macrodidyma, is a significant disease of grapevines both in New Zealand and worldwide. The aim of this study was to determine the pathogenicity of New Zealand I. liriodendri and D. macrodidyma isolates in two grapevine rootstocks as callused and rooted propagation material. Three isolates each of I. liriodendri and D. macrodi ...

- ... Downy mildew, caused by Peronospora sparsa, is a major disease of boysenberry (Rubus sp.) in New Zealand. The use of systemically infected plants for propagation has resulted in young plants being infected. To limit infection of new boysenberry canes prior to use in tissue culture two treatments, heat (34 °C) and fungicide sprays (mancozeb and phosphorous acid) + heat treatment were applied. Survi ...
