Banana peppers grow into a long shape that resembles a banana and are one of three colors: red, orange or yellow. All peppers, including banana peppers, are susceptible to pests and diseases that cause the leaves to curl and wilt.
Aphids
Aphids have small, black bodies and live on the undersides of leaves on banana pepper plants. They cause the leaves they live on to deform and curl. They also exude a sticky substance known as honeydew, which serves as a breeding ground for black sooty mold. Use insecticidal soap to treat for aphids.
Thrips
Thrips are small, flying
Wilt Disease
Two fungi known as verticilium and fusarium, which are present in the soil, cause wilt diseases. Symptoms include the wilting and upward curling of the leaves as well as a yellowing color. If allowed to continue, the roots and stems become affected as well.
