Final diagnosis


Tomato spotted wilt virus (TSWV)

Numerous necrotic lesions of small dimensions cause the leaf blades of these leaflets to turn yellow and give them a bronze tint <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i> , TSWV)
Some portions of the leaf blade of these leaflets are necrotic and show a bronze tint; they also have a more or less tendency to curl up. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
These young, chlorotic leaflets show a light tan tint and numerous tiny brownish lesions. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
Almost all of the leaflets of this plant have a more or less intense bronze tint. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
Dark brown necrotic patterns are developing on this leaflet. In places, we can distinguish the beginnings of rings. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
A few spots with concentric rings are clearly visible on the blade of this leaflet. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
In addition to the sometimes concentric chlorotic rings, dry lesions, more or less corky cracks, are sometimes present on the fruits. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
More or less wide chlorotic rings are clearly visible on this still green fruit. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
Several dry necrotic changes and corky cracks are clearly visible on these still green fruits. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
We can clearly see on this fruit a few superficial brown lesions in association with very marked dry corky bursts. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
Spherical virus particles 85 nm in diameter. The presence of a lipid envelope gives them a particular appearance. <b> Tomato spotted wilt virus </b> (<i> Tomato spotted wilt virus </i>, TSWV)
