IDaids for Xanthomonas diseases

We were motivated to select this set of IDaids by a recent quarantine expansion for citrus canker in Texas. Citrus canker is one of many plant diseases caused by Xanthomonas species. Xanthomonas pathovars (pathogenic varieties within a species) tend to be highly host-specific, and citrus is only one of the economically important plants that they can infect. We chose IDaids that illustrate the range of crop and horticulture plants Xanthomonas affects.

Be on the lookout for IDaids focusing on citrus canker in the near future.
