Cereal Rust Report Season 2009
Volume 7, Issue 7, 10 August 2009
Colin Wellings
The first confirmed sample
of the ‘WA Yr17’ pathotype for the 2009 season was collected
from a crop of Marombi wheat located at Coolah, northern
NSW. The crop was sown for grazing in mid March; stripe rust
was observed in early July and sampled for pathotype tests
in mid July. Marombi has been popular for its dual purpose
value in grazing and grain production in certain regions.
However its seasonal vulnerability to stripe rust, leaf rust
and wheat streak mosaic virus suggests that it should be
replaced with alternative long season varieties.
