Final diagnosis


Xanthomonas vesicatoria (Bacterial scab )

Xanthomonas1
Xanthomonas3
Xanthomonas5
On the leaflets, brown spots, even brownish, sometimes slightly angular, dot the blade. <b> <i> Xanthomonas </i> sp. </b> (bacterial scab, bacterial spot)
More elongated, brown to black lesions are seen on the stems and petioles. <b> <i> Xanthomonas campestris </i> pv. <i>vesicatoria</i> </b> (bacterial scab, bacterial spot)
Stem damage caused by <b> <i> Xanthomonas </i> sp. </b> (bacterial scab, bacterial spot)
Xanthomonas2
Xanthomonas7
Xanthomonas6
Some of the many brown spots covering these leaflets are more or less necrotic. Cankerous, corky lesions, 3 to 4 mm in diameter, are clearly visible on one of the fruits. <b> <i> Xanthomonas </i> sp. </b> (bacterial scab, bacterial spot)
Xanthomonas4
Brownish, rounded spots 4 to 5 mm in diameter develop on the most exposed portions of the fruit. A more or less large fatty halo can surround them. <b> <i> Xanthomonas </i> spp. </b> (bacterial scab, bacterial spot)
Four pustular and corky spots, oily on the periphery, are clearly visible on this still green fruit. <b> <i> Xanthomonas </i> sp. </b> (bacterial scab, bacterial spot)
Ultimately, the lesions are suberized and cracked (this symptom reminiscent of scab spots on apple). <b> <i> Xanthomonas </i> sp. </b> (bacterial scab, bacterial spot)
