Soil insect pests can be extremely problematic in Louisiana sweet potato production. The majority of insect damage in sweet potato occurs on the root surface and consists of unattractive scars and holes. The market tolerance for this cosmetic injury is very low, and minimal insect damage can drastically affect the marketability of the crop.

Effective weed management is a critical aspect to successful sweet potato production since weeds compete for nutrients, water and sunlight and impair crop yield and quality. Perennial weed management, preplant burndown and in-season management included.

Cucumber beetles (rootworms) are significant insect pests of sweet potatoes in Louisiana. Adults and larvae of these insects feed on sweet potatoes, but larvae are the most damaging. Descriptions of the banded cucumber beetle and the spotted cucumber beetle, as well as management strategies for these insects, are included in this publication. (PDF Format Only)

The Sweet Potato Research Station will host a field day Aug. 14.

Sweet potatoes are subject to attack by soil and foliage insect species throughout the growing season. Sweet potato weevils may be a problem in storage. Insect damage causes economic losses in quality and overall yield, and growers sustain significant losses to root-feeding soil insects.
