Notes: Stem rust is common in New Zealand on a wide range of introduced grasses; in species listed,
Deyeuxia avenoides and Poa anceps are endemic, and Agropyron scabrum, Deschampsia
caespitosa, Echinopogon ovatus, and Hierochloe redolens are indigenous (McNabb,
19626). The aecidial stage on Berberis has not been collected in New Zealand. The species B.
aristata commonly used for hedgerows is immune to rust (Allen, 1961 b). The uredospore stage
of this rust occurs in autumn and winter on a number of species of grasses. In wheat-growing areas
in Canterbury stern rust is not a problem, but in the North Island infection may be heavy and cause
considerable crop losses. Allen (1961b) listed the Australian varieties `Festival' and 'Mengawi' as
stem rust resistant. McEwan (1964) showed that a new rust race was present in New
Zealand,which infected 'Festival', he suggested the resistant varieties 'Gamerya' and 'Mengawi' for
planting in areas in the North Island where stern rust frequently occurs.
