List of sweet potato diseases

Sweet potato diseases are a variety of plant diseases that affect the sweet potato (Ipomoea batatas). These diseases can be caused by fungi, bacteria, viruses, and nematodes, and can result in significant crop loss. This article provides a comprehensive list of sweet potato diseases, their causes, symptoms, and potential treatments.

Fungal diseases

Black rot (Ceratocystis fimbriata) is a fungal disease that causes dark, sunken lesions on the sweet potato. The disease can be controlled by using disease-free planting material and rotating crops.

Fusarium wilt (Fusarium oxysporum) is a soil-borne fungus that causes wilting and yellowing of the sweet potato plant. Control measures include crop rotation and the use of resistant varieties.

Southern blight (Sclerotium rolfsii) is a fungal disease that causes wilting and rotting of the sweet potato plant. The disease can be controlled by deep plowing and crop rotation.

Bacterial diseases

Soft rot (Erwinia carotovora) is a bacterial disease that causes soft, watery rot of the sweet potato. The disease can be controlled by using disease-free planting material and avoiding injury to the tubers.

Bacterial wilt (Ralstonia solanacearum) is a bacterial disease that causes wilting and yellowing of the sweet potato plant. Control measures include crop rotation and the use of resistant varieties.

Viral diseases

Sweet potato feathery mottle virus (SPFMV) is a viral disease that causes mottling and distortion of the sweet potato leaves. The disease can be controlled by using virus-free planting material and controlling insect vectors.

Sweet potato chlorotic stunt virus (SPCSV) is a viral disease that causes stunting and chlorosis of the sweet potato plant. Control measures include the use of virus-free planting material and controlling insect vectors.

Nematode diseases

Root-knot nematode (Meloidogyne spp.) is a nematode disease that causes galling and distortion of the sweet potato roots. The disease can be controlled by using nematode-free planting material and rotating crops.

Reniform nematode (Rotylenchulus reniformis) is a nematode disease that causes stunting and yellowing of the sweet potato plant. Control measures include crop rotation and the use of nematicides.
