The first report of Tomato spotted wilt virus on gerbera and chrysanthemun in Venezuela.

Abstract

For the past 2 years, greenhouse-grown gerbera (Gerbera jamesonii) and chrysanthemum have been observed displaying symptoms resembling those associated with tospoviruses. Symptomatic plants showed concentric rings, irregular chlorotic blotches and deformation on leaves. Disease incidence was estimated at 30%. The causal pathogen was identified as Tomato spotted wilt virus (TSWV) based on pathogenicity, ELISA and RT-PCR analyses. This is thought to be the first confirmed report of TSWV infecting gerbera and chrysanthemum in Venezuela.
