Stripe Rust
In Europe new multivirulent strains appeared in at least four NW-European countries in 2011: UK, France, Denmark, Sweden. Several wheat varieties became affected and the new strains seems to be very aggressive based on field observations. It is first time ever recorded in Europe that a single strain emerges at this geographical scale in high frequencies in the same growing season, suggesting large scale long-distance aerial spore dispersal autumn 2010/ spring 2011 from an unknown source. Since 2011 the two races Warrior and Kranich have spread across Europe and now dominates.
Four PCR-based markers uniquely identifying aggressive strains PstS1/ PstS2 and differentiating these from other known Pst strains are being developed at the Global Rust reference Centre. For isolates collected in Denmark and Sweden, preliminary results suggest that the new strain may be a recombinant involving aggressiveness.
