Bacterial spot can result in severe damage to sweet pepper, tomato or pimento crops to the extent that it is a limiting factor to successful production. The bacterium (Xanthomonas vesicatoria) attacks leaves, fruits and stems causing blemishes on these plant parts. Outbreaks of leaf spotting have resulted in leaf drop and poor fruit set in the field. The defoliation from leaf spotting can increase the incidence of sun scald on the fruit. Badly spotted fruit is of little value. Injury from this disease allows secondary fruit rotting organisms to get into the fruits, causing further damage.
