PPFS-VG-17: Bacterial Spot of Pepper and Tomato

Erica Fealko, Nicole Ward Gauthier | Sep. 2, 2021 (Major Revision)

Bacterial spot can result in severe damage to tomato, sweet pepper, and pimento crops. The bacterium 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. Defoliation due to leaf spotting can increase the incidence of sun scald on fruit. Fruit infections result in badly spotted fruit, which are of little market value. In addition, fruit injury from this disease allows entry of secondary fruit rotting organisms, causing further damage.
