- BYDV is mainly transmitted by several aphid species, while WDV is spread by a leafhopper species.
- Transmission occurs predominantly in autumn; mild temperatures increase the vectors’ activity and reproduction.
- Later sowing dates and consistently removing volunteer cereals can reduce the risk of infection.
- Insecticides against aphids are considered useful above 10 percent infected plants; no approved insecticides are available against WDV.
