The sweet potato industry readily accepts new cultivars, which leads to a quick shift in the most widely grown cultivar. Beauregard, released in 1987, is currently the dominant cultivar grown in the U.S. [ 13 ] Beauregard is considered to be moderately resistant to R. stolonifer although sporadic, heavy losses during shipping are known to occur.
Not only are losses clearly a waste of food, but they also represent a similar waste of human effort, farm inputs, livelihoods, investments, and scarce resources such as water. [2] Post-harvest losses for horticultural produce are, however, difficult to measure. In some cases everything harvested by a farmer may end up being sold to consumers.
The pest of greatest concern for farmers is the sweet potato weevil (Cylas spp.), which can enter the tuber prior to harvesting, proliferate in storage, and cause up to 50% loss in yields. [ 3 ] [ 9 ] Simple techniques can be used to minimize the threat of the sweet potato weevil.

After the field, post-harvest processing is usually continued in a packing house. This can be a simple shed, providing shade and running water, or a large-scale, sophisticated, mechanised facility, with conveyor belts, automated sorting and packing stations, walk-in coolers and the like. In mechanised harvesting, processing may also begin as ...
Sweet potato is associated with the new year festival of Makahiki, where the first fruits of the harvest (kāmalui hou) were offered to the gods, typically sweet potatoes and taro. [ 25 ] By the mid-1800s, traditional rain-fed sweet potato cultivation in Hawaii ceased due to depopulation and damage caused by introduced Western grazing animals ...
