Rhizoctonia Limb and Pod Rot

[caused by Rhizoctonia spp]

Rhizoctonia limb and pod rot is some­times confused with southern stem rot. While both affect the stems, Rhizoctonia does not produce white stringy growth or tan sclerotia. Dark- or grayish-brown lesions are usually found where the under­sides of stems touch the soil. Lesions may have a dark border and often have a target-like appearance.

Rhizoctonia pod rot affects pods at all stages of development and is the most destructive aspect of the disease. This disease is most common in moist fields or where vine growth is thick. A foliar blight may be present in these conditions. Irrigated fields are most severely attacked. Management practices and fungicides are the same as for southern stem rot.
