Bacterial leaf spot can also spread to your peppers. The remaining fruits may not be harvestable because infected peppers are smaller and sometimes have deformities. The bacterial infection is not the main cause of pepper decay, but the lesions on the fruit make them susceptible to other pathogens that can cause decay and other diseases.
