Pesky Pea Problems


Prevention Steps

  1. Select disease-resistant seed varieties.
  6. Pull out and burn disease-ridden plants.

Insect Pests










Damping-off fungi, which cause seed decay, are prevalent during cool, moist weather. To avoid this problem, plant only after the soil is dry enough to work easily.

Fusarium wilt causes pea leaves to turn yellow. The plants are stunted and eventually wilt. Fusarium wilt symptoms are similar to those of root rot. The main difference is that the base of the stem of a plant affected with wilt isn't withered, and the inside of the stem shows discoloration. This fungus lives in the soil and enters the plant through its roots. Check seed catalogs or seed packets for resistance to the disease. Fusarium-resistant varieties will be marked with an F. For other control measures see root rot.

Mosaic virus is spread by aphids and carried within infected seeds. The plants usually become stunted, leaves turn light colored and mottled, and pods are few and poor in quality. To reduce infection, remove pea plants that show leaf mottling and control aphids.

Powdery mildew is a fungal disease that's most troublesome in warm weather. A white or grayish powdery mold appears on the pods, leaves and stems. To combat this problem, turn under or compost the pea vines as soon as the harvest is over, water in the morning only and plant resistant varieties.

Root rot is caused by soilborne fungi that often kill plants at flowering time. Plants turn pale yellow and may be stunted. The stems wither near the ground, and the plants often die back or collapse. To avoid root rot, plant peas in well-drained soil. Remove and destroy affected plants. Rotate crops.

Precautionary Note:

If you choose to use commercially available sprays or dusts, purchase the least-toxic preparation that will do the job effectively.

When using a commercial spray or powder, read the instructions three times: before buying to make sure you buy the right substance; before using to be sure you use it correctly; and again before storing in order to put it away properly.

It's often best to contact your local extension service for advice when a problem arises. Not only can extension agents help you to identify the unwanted pests in your garden, they'll also suggest the best remedy for dealing with them in your area.
