Wheat yellow rust management

Yellow rust can reduce wheat yields by 50% in untreated crops. These losses can be prevented using a combination of varietal resistance and fungicides. In the last few years, changes in the yellow rust fungus have limited the use of varietal resistance to manage the disease, putting greater emphasis on fungicides.

New races of the yellow rust fungus developed in 2011 that can attack many popular varieties.

The impact of these races on varietal resistance is being examined as part of the UK Cereal Pathogen Virulence Survey (UKCPVS).

Although the HGCA Recommended List provides useful information on varietal resistance, it can only reflect the previous cropping season.

There is no substitute to monitoring crops regularly, including resistant varieties, to get an accurate picture of the current situation.
