Overall stunting of cantaloupe plant infected with curly top virus.

Cucurbits

Curly Top

Pathogen: Beet curly top virus (BCTV)

(Reviewed 11/05, updated 6/08)

In this Guideline:

SYMPTOMS

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.

COMMENTS ON THE DISEASE

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.

MANAGEMENT

No control is practiced.
