- Title
Review of Losses caused by Virus Yellows in English Sugar Beet Crops and the Cost of Partial Control with Insecticides.

- Abstract
From 1970 to 1975, before soil-applied pesticides were widely used by sugar beet growers in England, virus yellows is estimated to have caused an annual loss representing about 5 per cent of the crop's potential yield, equivalent to about £4.2 million at the 1974 price for beet. At least £0.9 million were spent annually by growers on insecticides to give partial control of yellows, probably giving a yield increase worth thrice that sum. When 20 per cent or more of sugar beet plants show symptoms of virus yellows at the end of August crop yields are appreciably decreased, and the proportion of the national crop area in this category during 1970-75 ranged from less than 1 to 86 per cent (averaging 30 per cent).
