The UK CerealPathogen Virulence Survey (UKCPVS) is calling for the industry to monitorcereal crops and send in diseased samples for analysis.
Managed by NIAB,and funded by HGCA and Fera, the UKCPVS tracks potential shifts in UK pathogenpopulations, identifying areas of concern particularly potential breakdown invarietal disease resistance.
Dr Sarah Holdgate,UKCPVS project manager based at NIAB, said: Our success relies on infectedwheat and barley leaf samples sent in by growers, agronomists, plant breedersand official trials operators.
May, June andJuly is the peak period for sampling and infected leaf material gathered fromacross the UK gives the team the pathogen isolates needed for robust testing.
The more sampleswe receive, the more chance we have to detect an issue before it becomes anestablished problem giving growers more time to act in the season and plantbreeders more time to adapt their variety selection processes.
The requestfollows the release of UKCPVS results in March which showedcereal rust populations in the UK have become increasingly diverse affectingvarieties in different, and often unpredictable, ways.
Disease samplingin 2015
Leaves showingsigns of wheat yellow rust, brown rust and powdery mildew, as well as barleypowdery mildew, are being requested.
Typical cropdisease symptoms can be seen in the photo gallery on the recently refreshed Cereal Disease Encyclopaedia.
Samples can betaken from any variety but varieties noted as resistant to the disease are ofparticular interest.
Simple samplingguidelines have been developed which should be followed to ensure samples reachthe FREEPOST UKCPVS address in the best possible condition.
