Bacterial Scorch of Redbud


This is a redbud in front of Fox
laboratories on Main Campus with scorch caused by the bacterial
pathogen Xylella If you take a look at the
leaf you’ll notice that necrosis begins at
the edge of the leaf and moves into the veins. Now something like this may also be seen on a plant that’s suffering from drought stress so this clues us in that the pathogen
is colonizing the vascular tissue and inhibiting the plant from properly
moving water This is a bacterial pathogen that’s
vectored through a leafhopper. You can see other scorch on some of the Sycamores on
campus and some other redbuds have it but
not all you can also see here some of the Passalora that will be noted in another video
