Re-emergence of stem rust on wheat in Western Europe

In a commentary in Communication Biology, published 4th February 2019, scientists evaluate the risks of re-emergence of wheat stem rust in Europe. In general, the wheat rust “problems” in Europe have been addressed via multiple national initiatives, but in 2018, a new EU H2020 research and innovation program was launched, dealing with all three…

Severe epidemics of wheat yellow rust in Argentina

In 2017, Argentina faced the worst epidemics of yellow rust since the 1930s. Based on samples collected at 22 epidemic sites in September, the Global Rust Reference Center (GRRC) has identified at least three distinct yellow rust genotypes. Two of these were identical to genotypes first detected in Europe and North Africa in 2015-16.

GRRC annual report on wheat yellow rust 2017 released

Unusual and severe epidemics of yellow rust were observed on several continents in 2017. In a number of cases, epidemic sites at different continents were inter-related by prevalence of genetically identical yellow rust genotypes and races.

Assessing the Stem Rust Situation in Western Siberia

Up to 2014 wheat stem rust was not considered of major importance in Western Siberia, but severe epidemics in 2015 and 2016 has changed the situation. New research to resolve stem rust epidemiology in the region and additional efforts in breeding for rust resistance is urgently needed.
