Peas

Visual Description:

White, powdery coating appears on leaves, stems, and pods, starting as small circular spots that expand to cover entire surfaces. Affected leaves may turn yellow and die prematurely. The disease spreads rapidly in humid conditions with poor air circulation. Severe infections can reduce yield and pod quality. Young pods may be stunted or distorted.

Visual Description:

Small caterpillars (about 1/2 inch) feed inside developing pods, leaving holes in the peas. External signs include tiny entry holes in the pods. When pods are opened, damaged peas and frass (insect droppings) are visible. The adult moths are small and gray-brown. Damage is often not noticed until harvest.

Visual Description:

Plants show stunting and yellowing, starting with lower leaves. Roots develop dark brown to black lesions and become soft and rotted. When pulled up, the root cortex may slough off, leaving only the central core. Severely affected plants wilt and die, especially in wet conditions. The disease can affect plants at any growth stage.

Visual Description:

Leaves develop light and dark green mottling with raised blister-like growths (enations) on the undersides. Pods may be distorted and show similar enations. Plants can be stunted with shortened internodes. Young leaves may be cupped or distorted. The virus can severely reduce yield and pod quality.

Visual Description:

Water-soaked spots appear on leaves, stems, and pods. These spots enlarge and turn brown with yellow halos. Lesions on pods may appear greasy. In wet weather, cream-colored bacterial ooze may be present. Severely infected leaves become brown and papery. Pod lesions can affect seed quality.

Visual Description:

Circular, tan to brown spots with dark borders appear on leaves, stems, and pods. Spots often show concentric rings and may develop tiny black fungal bodies. Stem lesions can girdle the plant, causing sections above to die. Pod spots can penetrate and affect the developing peas.
