Bacterial wilt and Southern stem blight are two common diseases that have no chemical methods for control. Planting this crop following a grass crop helps reduce these problems. Bacterial leaf spot may be a problem with peppers. Other disease problems include tobacco mosaic virus, alternaria leaf spot and fruit rot, anthracnose, and nematodes. Insects that may be a problem include cutworms, aphids, Colorado potato beetles, flea beetles, lace bugs, hornworms, and corn earworms.
Lace bugs are a common problem on eggplants.
European corn borer can be a serious pest problem on pepper. Contact your county Cooperative Extension office for methods to control these diseases and insects. Harvest Stems of pepper and eggplant plants are brittle. When harvesting the fruit, be careful not to break the stems off the plant. It is best to harvest the fruit by cutting the fruit stems with a sharp knife.
