Final diagnosis


Fusarium oxysporum f. sp. lycopersici (Fusarium wilt )

Subsequently, the yellowing spreads to several leaflets. <b> <i> Fusarium oxysporum </i> f. sp. <i> lycopersici </i> </b> (Fusarium wilt, <i> Fusarium </i> wilt)

FOL6
Subsequently, yellowing spreads to several leaflets located on the same side of the leaf. Note that several veins are still green. <b> <i> Fusarium oxysporum </i> f. sp. <i>lycopersici</i> </b> (Fusarium wilt, <i> Fusarium </i> wilt)
Chlorosis is now manifest, and its one-sided character is typical of vascular disease. <i><b> Fusarium oxysporum f. sp. lycopersici </b></i>(fusarium, Fusarium wilt)
The yellowing progressively gains several petioles located on one side of the leaf rachis. <b> <i> Fusarium oxysporum </i> f. sp. <i>lycopersici</i> </b> (Fusarium wilt, <i> Fusarium </i> wilt)
<b><i>Fusarium oxysporum</i> f. sp. <i>lycopersici</i></b> (fusariose, <i>Fusarium</i> wilt)
FOL3
A transverse section of the stem shows locally a rather marked browning of the vessels. The marrow is not affected. <b> <i> Fusarium oxysporum </i> f. sp. <i>lycopersici</i> </b> (Fusarium wilt, <i> Fusarium </i> wilt)
FOL4
Once the surface tissues of the stem are removed, the vessels show a more or less dark brown to brown tint. <b> <i> Fusarium oxysporum </i> f. sp. <i>lycopersici</i> </b> (Fusarium wilt, <i> Fusarium </i> wilt)
Marked browning of the vessels which have darker streaks in places. <b> <i> Fusarium oxysporum </i> f. sp. <i>lycopersici</i> </b>

FOL2
<b> <i> Fusarium oxysporum </i> f. sp. <i> lycopersici </i> </b> produces unicellular microconidia and crescent-shaped macroconidia with a maximum of 3 to 4 septa. It also forms thick-walled, intercellular or terminal chlamydospores and isolated or in chains. <b> Fusarium wilt (<i> Fusarium </i> wilt) </b>
