Barley Yellow Mosaic Virus (BYMV)

Pathogen

Virus

Hosts

Barley

Symptoms

This disease has now spread widely across the UK. The first symptoms are small yellow patches which appear in the crop from February and are similar to waterlogging or acidity effects. The leaves develop a streaky yellow look, brown at the tips and often have in-rolling leaves leading to a spiky appearance. The plants are stunted and mature late.

Development

The virus is spread by a root infecting fungus. Moving soil will spread the virus through the field. There appears to be some differences in varietal susceptibility, some varieties having a high level of tolerance to BYMV.

Importance

Yield and quality reduction.
