ABSTRACT: A study was conducted to
establish the prevalence and severity of Tomato
leaf curl viral disease in
the major agroclimatic tomato cultivating regions of Gujarat. Districts of Gandhinagar,
Kheda, Mehsana, Panchmahal and Rajkot of Gujarat were surveyed. The survey
aimed at assessing types of symptoms, severity and yield loss in the tomato
plants. Results obtained indicate vast spread of Tomato leaf curl virus in majority of the tomato fields in Gujarat.
The maximum infection was observed in the Kheda district with almost complete
crop loss followed by Mehasna and Gandhinagar districts showing high prevalence
of infection. Influence of the climatic conditions and cultural practices were
observed on the level of infection.
