They occur most frequently on sandy soils, but most soils can harbor these pathogens. Whenever nematode-susceptible plants are grown in your fields, they can quickly increase nematode populations. Rotation to nonsusceptible crops, particularly grasses and small grains, can dramatically reduce nematode populations. If you suspect nematodes in your field, contact your local county Extension agent, who can help you sample the field to determine if nematodes are a problem. Check with your local county Extension agent or consult the latest edition of the Georgia Pest Control Handbook for appropriate nematicides.
Several diseases can affect southernpeas.
Anthracnose - Stems, leaves, and pods are affected. Dark brown to black sunken areas appear on affected parts. Often a beardlike structure can be seen within these lesions with a hand lens. Fusarium Wilt - Plants are stunted and leaves of infected plants often are wilted. Stems cut lengthwise at or near the soil surface will show a brown discoloration in the vascular tissue.
