| Curly top, a virus disease transmitted only by the beet leafhopper, was a serious threat to the sugarbeet industry in south-central Idaho from 1919 through 1941 and to dry edible and snap bean production from 1924 through 1957. The frequency and severity of damage are charted from 1919 through 1977. The development of plant varieties resistant to curly top is attributed as the major factor in lessening damage to sugarbeets since 1942; the development of plant resistance in beans proceeded at a slower rate, but has also become a major factor in lessening damage. Other possible factors discussed are: (1) size of overwintering beet leafhopper populations, (2) early spring migration of beet leafhoppers, (3) insecticidal control in desert areas, (4)... |
