Beet Mosaic ‐ a Declining Disease in England

SUMMARY Surveys made by fieldmen of the British Sugar Corporation since 1946 showed that beet mosaic virus has declined in importance. Root crops in the Felsted and Spalding beet‐sugar factory districts have been most affected by the virus. Disease control in beet‐seed crops, well‐timed treatment of sugar‐beet root crops with systemic insecticides, and a decrease in the mangold crop acreage have contributed to its decline. However, common weeds, especially wild beet are persistent hosts for the virus.
