The problem of pea plants wilting in the garden can be as simple as a need for water, or peas wilting may also signal a serious, common disease called pea wilt. Wilt on peas (the disease) is soil borne and may or may not devastate the crop.

Reasons for Pea Plants Wilting

If you have pea plants wilting in the garden, check first to make sure the soil isn’t dried out. Examine stems near the bottom for bright or unusual colors of yellow, orange or red. This may only be visible by cutting the stem open as the disease begins.

Wilt that is not corrected by watering is the surest sign that your plants have a form of disease. Several types of Fusarium wilt and Near wilt are known to horticulturists, these may perform differently when infecting your garden plants.

Peas wilting from these diseases exhibit symptoms on stems and roots. They turn yellow or reddish orange; plants become stunted and may die. Fusarium pea wilt sometimes spreads through the garden in a circular pattern. Near pea wilt has similar symptoms, but is not as likely to destroy the entire crop.

Plants damaged by wilt on peas should be removed from the garden, along with roots. Pea wilt disease is easily spread by tracking soil into healthy parts of the garden, by cultivation and tilling, and by the diseased plants you have removed. Plants affected by wilt on peas should be burned. There is no chemical control effective for this disease.

Plants affected by pea wilt often do not produce pods, or pods are small and underdeveloped. Near wilt on peas that are older and have shown vigorous growth may not be as devastating, these plants may continue to produce a viable, useable crop.

Preventing Pea Wilt

Wilt on peas can be avoided by good cultural practices, crop rotation and planting disease resistant varieties. Plant peas in a different area of the garden each year. Plant in soil enriched with organic compost that drains well. Don’t overwater. Healthy plants are less likely to succumb to disease.

Choose seeds that are labeled resistant to wilt. These will be labeled (WR) on the packet. Resistant varieties may grow a healthy pea crop in the infected soil. Fungi of the disease may remain in the soil for 10 years or longer. Non-resistant varieties should not be planted in the area again. Choose an entirely different growing spot, if possible.
