Pathogens

Differential sets are crucial for race analysis. The lack of consistency in sets among rust labs hampers international result comparison. Recognizing the threat of stem rust, a global panel of rust experts established a standardized international set. BGRI partners now use this core set for global consistency, allowing labs to make optional additions based on local needs.

Source: GRRC report: Samples of stem rust infected wheat from Italy, 17 November 2016

From Rusttracker:

Results of extensive lab tests of samples of stem rust have shown that the 2016 stem rust epidemics in Sicily were caused by a new, highly virulent variant of race TTTTF. The samples were collected during serious and unusual outbreaks of wheat stem rust on both durum wheat and bread wheat in Sicily during April – June 2016…Read more at Rusttracker
