The wheat disease stripe rust caused crop losses estimated at $20 million in New South Wales during an epidemis in 983. Economic crop losses were reported in neighbouring States and as far westas Ceduna in South Australia. In some States large areas were sprayed with fungacide at considerable cost to control disease spread.

Wheat stripe rust has not been found in Western Australia yet, but all current evidence indicates that it will eventually reach this State.When it does, it has the potential to cause considerable crop losses every year, unlike the spasmodic losses from stem rust, and it will greatly influence the varieties that can be grown.
