FORL2
Pinkish-brown cortical lesion extending several centimeters above the neck. <b> <i> Fusarium oxysporum </i> f. sp. <i> radicis-lycopersici </i>, FORL (Fusarium root rot, <i> Fusarium </i> crown and root rot) </b>
FORL5
Brown, slightly depressed canker developing on one side of crown and stem only (flame-shaped). <b> <i> Fusarium oxysporum </i> f. sp. <i> radicis-lycopersici </i> (FORL) </b> (<i> Fusarium </i> crown and root rot)
Canker brown, moist, well demarcated, depressed (pushing), covered with salmon mucus. <b> <i> Fusarium oxysporum </i> f. sp. <i> radicis-lycopersici </i>, FORL (Fusarium root rot, <i> Fusarium </i> crown and root rot) </b>
FORL4
FORL1
Reduced root system, brown and rotten, chocolate brown vessels in the lower parts of the stem. <b> <i> Fusarium oxysporum </i> f. sp. <i> radicis-lycopersici </i> (FORL) </b> (<i> Fusarium </i> crown and root rot)
Brown, rotten roots and browning of the vessels are often features of <b> <i> Fusarium oxysporum </i> f attacks. sp. <i>radicis-lycopersici</i> </b> on tomato roots.
Vascular browning may extend into the stem for several centimeters above the crown. The vessels then take on a sometimes very dark brown tint. <b> <i> Fusarium oxysporum </i> f. sp. <i> radicis-lycopersici </i> (FORL) </b> (<i> Fusarium </i> crown and root rot)
