Figure 1. Lesions of bacterial leaf spot on a pumpkin leaf are often a light brown and maybe somewhat angular in shape.
Figure 2. Close up of lesions on pumpkin of bacterial leaf spot.
Figure 3. The bacterial spot lesions on the leaf in the foreground are a darker necrotic shade than the lesions in Figure 1 and 2.
Figure 4. A specialty pumpkin with lesions of bacterial leaf spot of pumpkin. Note that lesions may have a water-soaked appearance. Older lesions may have a light necrotic center.
Figure 5. Lesions of bacterial spot on this pumpkin appear necrotic and may have small depressions in the center.
Figure 6. This immature pumpkin has lesions of bacterial spot of pumpkin. The lesions have the appearance of light necrotic scabs. The larger lesions are probably where one of the bacterial spot lesions became infected with a fungus that started in one of the bacterial spot lesions.
Figure 7. Bacterial spot lesions on a pie pumpkin.
Figure 8. Several necrotic lesions caused by bacterial spot of pumpkin can be observed here. One lesion is much larger and has probably been infected by a secondary fungus.
Figure 9. Typical lesions of bacterial spot can be observed on this pumpkin along with one that has been infected by secondary fungi causing it to rot through the pumpkin rind.
