Goondiwindi, New South Wales
August 15, 2004
Confirmed outbreaks of stripe rust
at Bellata and Gurley, in north-west New South Wales, should
ensure even more bottoms on seats at a seminar on cereal foliar
disease in Goondiwindi on Tuesday (August 17).
Rust specialist Harbans Bariana will be one of several
pathologists at the special Grains Research Update to talk about
rust in wheat and to answer questions from the floor about the
disease.
Dr Bariana, who works on the Australian Cereal Rust Control
program with the University of Sydney, says he would rather
discuss what his Goondiwindi audience wants to know about rust
than deliver a long prepared presentation.
The Goondiwindi Update, to be held at the Royal Hotel from 8.30
am, is an extension of the usual, annual round of updates
organised by the Grains
Research and Development Corporation (GRDC) with the support
of the Queensland and NSW Departments of Primary Industries,
AgForce and the NSW Farmers Association
It was called to ensure leading growers and their advisers are
better prepared to respond to disease outbreaks in the current
season and into the future.
The GRDCıs coordinator of northern region updates, John Cameron,
says the confirmation of as yet unidentified strains of rust in
the variety Clearfield Janz at Gurley and in Sunsoft 98 at
Bellata should see growers and their advisers paying special
attention in scouting susceptible and moderately susceptible
varieties to look for signs of rust.
"The strains of rust in these two cases have yet to be
identified, because the process can take a fortnight, or even
longer," Mr Cameron said.
"But there is considerable industry concern that they might be
of the new, West Australian strain of stripe rust that showed
itself capable of breaking down established rust resistances
when it emerged last season.
"We believed that Janz had the reputation of being one of the
more rust resistant varieties around, and the Sun prefix wheats
from the University of Sydney/Sunprime program also have
reputations for good degrees of resistance.
"Itıs also a worry that the two paddocks reported as rust
infected were planted early enough for the stronger adult plant
resistance to have started to work in those crops."
Mr Cameron said he was sure growers and advisers in northern NSW
and southern Queensland would be already scouting paddocks for
signs of disease but a day spent at the Goondiwindi Update on
Tuesday would improve their skills in disease identification and
their understanding of how to respond.
Besides Dr Bariana, the speaker list at the update would include
specialist disease pathologists Steven Simpfendorfer and Greg
Platz. |
