Frankliniella occidentalis and tomato spotted wilt tospovirus in Argentina

In Argentina, plants of chrysanthemum showing symptoms of chlorotic ringspots, line patterns and necrosis on the leaves, stunting, necrotic streaks on the stem, pith necrosis and flower distortion were observed during summer 1993-1994 in commercial glasshouses near La Plata (Buenos Aires). In nearly 60 % of the greenhouses, 5-70 % of the most susceptible cultivars (cv. Palisade and Southern Sun) were presenting symptoms. The causal agent has been identified as being tomato spotted wilt tospovirus (potential EPPO A2 quarantine pest). This is the first outbreak of this disease in Argentina on chrysanthemums. In addition, the authors pointed out that it appears simultaneously with the first record of Frankliniella occidentalis (EPPO A2 quarantine pest) in the country.
