Symptoms of curly top include severe stunting, stiffness, short
internodes, and leaves that are darker green than normal. Runner tips tend to
turn up. Plants infected in seedling stage die. Leaves may roll upward and have
a crinkled appearance. Older plants may turn
yellow and
die.
Curly top is rare in cucurbits. The virus is transmitted by the beet leafhopper, Circulifer tenellus;
the leafhopper retains the virus and is capable of transmitting it for its
entire life. Curly top virus has a wide host range including many weeds.
No control is practiced.
