According to the literature, the cause of tomato yellows (western yellow blight) has remained a mystery since 1906. It was not until 1927 that the beet leafhopper, Eutettix tenellus (Baker), which transmits curly top to sugar beets, was associated as a carrier of the same disease to tomatoes.
Carsner and Stahl (1924)2 reported tomato as susceptible to curly top, but from a study of the symptoms in the greenhouse, they state that “this disease has not been found in commercial plantings.”
McKay and Dykstra (1927) came to the conclusion, on circumstantial evidence, that tomato yellows is caused by the virus of sugarbeet curly top.
Shapovalov (1927a) proved conclusively that curly-top virus, when introduced into the tomato plant by means of infective beet leafhoppers, produced typical symptoms of yellows with tomatoes grown out-of-doors.
