Florida scientists received a grant to investigate strategies to control bacterial spot in tomatoes. The disease creates major challenges for commercial production throughout Florida and across the United States.
Bacterial spot first affects the leaves of the plant, developing black spots the size of shotgun pellets. Then the leaves blacken and ultimately drop. The fruit is still edible but can develop little blisters, making them practically unmarketable.
The plant pathogen that causes bacterial spot in the southeast is called Xanthomonas euvesicatoria pv. perforans. The "pv." abbreviation stands for "pathovar" and is used to designate a specialized group of bacteria with the same or similar characteristics within a species.
