Abstract :

The agent of beet curly top disease is Beet curly top virus (BCTV). BCTV, involved in the genus of Curtovirus, has a single-stranded DNA (ssDNA) genome with twine particles. It is persistently transmitted by Circulifer tenellius (Baker) and C. haematoceps (Mulsant and Rey) which belong to the family Cicadellidae and the order Homoptera. Beet curly top disease (BCTV) first occurred in USA in 1888 and continued to affect especially sugar beet and the other crops up to date. Since the resistant cultivars to the disease can only help to reduce the impact of the virus and it is difficult to control its vectors by means of chemical methods, the efforts to combat the curly top disease of sugar beet is limited. The virus can cause a significant crop yield reduction from time to time and discontinuing sugar beet cultivation.
