First reports of wheat stripe rust for 2023 suggest widespread over-seasoning
The first detection of stripe rust on 7 July this year was about nine weeks later than in 2022; then, it was first detected on 20 May and one of the worst stripe rust epidemics experienced in eastern Australia ensued. Reports of stripe rust after the first detection this year have come from Bethungra, NSW (14 July); Tubbul, NSW (20 July); Smeaton, Victoria (20 July); Naracoorte, South Australia (24 July); and Cressy/Longford, Tasmania (26 July).

Making sense of varietal responses to new rust pathotypes
Knowing the presence of resistance genes in a variety is important in predicting and explaining how a variety will perform if and when a new rust pathotype appears. This is well illustrated by the events that unfolded following the introduction of wheat stripe rust pathotype 198, which originated from either Europe or South America.
