Phomopsis lesions (Phomopsis vexans)

Beginning spots on aubergine leaf; they are rather circular beige to greyish, brown on the periphery. <b><i>Phomopsis vexans</i></b>.
Large spot on eggplant leaf. Irregular and necrotic, it is surrounded by a chlorotic halo. <b><i>Phomopsis vexans</i></b>.
Eggplant stem completely destroyed by <b><i>Phomopsis vexans</i></b>. Stem and branches are damaged, all the leaves have fallen.
Several eggplant twigs are affected by the development of <b><i>Phomopsis vexans</i></b>. Dark longitudinal lesions encircle them for several centimeters, presenting a black-brown hue, whitening in places. Many leaves have fallen.
Twigs damaged by <b><i>Phomopsis vexans</i></b>.
Eggplant twigs necrosed as a result of the development of <b><i>Phomopsis vexans</i></b>. The inside of the stem appears to have been altered.
This eggplant twig shows a lesion extending over several centimeters. Rather dark to blackish in color on the periphery, it is lighter or even white in its center. <b><i>Phomopsis vexans</i></b>
A longitudinal section in an eggplant twig invaded by <b><i>Phomopsis vexans</i></b> shows that all the internal tissues are altered, even decomposed.
