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) increased
general use of pesticides, (5) rangeland improvement
by reseeding, and (6) increased size of the cultivated area.
The recent increase in the use of beet varieties less resistant
to curly top poses a new problem to that industry.
