Nationwide survey indicates high levels of TuYV infection this season

Early results from a nationwide survey are indicating high incidences of TuYV infection in the current oilseed rape crop.

Carried out by Dr John Walsh of Warwick University on behalf of breeders Limagrain UK,

the survey which will be completed by the end of May, will provide a comprehensive indication of TuYV infection hotspots across the country. TuYV is thought to be the most important, yet least understood viral disease in oilseed rape.

“Overall results so far are showing generally high levels of infection across the three regions that have been tested as part of a PhD project led by Dr Walsh; results from the south of England have detected incidences of as high as 80%, in Somerset incidences of up to 74% and in Yorkshire incidences of up to 72%, whereas in Cardiganshire we found incidences of up to 46%. “
