Rust is a social disease and threat to all
CONTINUING PRODUCTION of rust-susceptible wheat varieties poses a major threat to the Australian wheat industry and growers should stop growing rust-susceptible varieties.
GRDC Winter Cereals Improvement Program Manager Ross Gilmour told the industry audience at Grains Week that those who continue growing susceptible varieties are putting the industry at risk. "Fungicides cannot provide
the industry with the protection necessary," Dr Gilmour said.
"In the past three years, four rust-resistance genes have been lost to pathotype changes. This is not sustainable. It is absolutely imperative that the whole industry moves towards the objective of growing rust-resistant varieties.
"The responsibility rests not just on the researchers responsible for delivering resistant varieties. Growers have a responsibility to dis-adopt susceptible varieties."
