The Q&A Archives: Holes In Sweet Potatoes

Question: I grew and harvested large sweet potatoes. However, they all had many holes in them. Is it an insect problem, planting problem, soil problem, etc?

Answer: Several insects make holes in sweet potatoes. For example, wireworms and flea beetle larvae make small, shallow holes which enlarge or deepen as the potato grows, the sweet potato flea beetle larva makes narrow channels or grooves just under the skin and grubs gouge out broad, shallow areas. You might want to take a sample to your County Extension (349-1247) for a specific ifentification and the most up-to-date control recommendations.
