“…To prolong storage time a curing process can be implemented whereby the skin of the sweetpotato root is induced to harden, rendering it less susceptible to physical damage and entry of disease organisms-this can extend the shelf life up to 6 months. The curing process is initiated by keeping the freshly-harvested roots at a temperature of 29 to 30 C and high relative humidity (90-95%) for four to 7 days, often followed by a drop in storage temperature to just under 13 C (Ray et al 2010;Estes 2009). It has also been noted that maintaining proper ventilation during the curing process is key to ensure the necessary exchange of carbon dioxide and oxygen which takes place by the stored roots (Smith et al 2009;Louisiana Insect Pest Management Guide 2023).…”

“…It has also been noted that maintaining proper ventilation during the curing process is key to ensure the necessary exchange of carbon dioxide and oxygen which takes place by the stored roots (Smith et al 2009;Louisiana Insect Pest Management Guide 2023). In the USA, the curing step, when implemented soon after harvest, has been instrumental in obtaining a prolonged shelf-life and optimized flavor for harvested roots; it has been estimated that up to 90% of the sweetpotato crop in the USA undergoes a curing step (Estes 2009). However, extended storage provides additional opportunities for SPW infestation and damage.…”

Africa accounts for a significant portion of the world’s sweetpotato production where it is widely grown as a staple crop. In sub-Saharan Africa (SSA), sweetpotato serves as an important year-round source of calories and nutrition, a form of income for smallholder and pre-commercial farmers, and is increasingly used as silage for animal feed. However, yield per hectare is considerably lower in SSA than from other regions primarily due to sweetpotato weevils (SPW, Cylas spp., Coleoptera: Brentidae). Weevil feeding causes physical damage to the root and can induce chemical responses that give the storage root a bitter taste, both of which make them unmarketable. Commercial growers in many developed countries rely on frequent chemical treatments and strict quarantine regulations to control SPW, however, this approach is currently not practical for many areas of SSA. In this paper we, (1) outline factors that contribute to SPW infestation; (2) review available strategies and ongoing research for control of SPW, including chemical pesticides, biological control (macro-organismal as well as microbial control), cultural practices, selective breeding, and biotechnology; and (3) discuss the potential for implementing an integrated pest management (IPM) approach that leverages a combination of techniques. We rationalize that a multifaceted strategy for SPW control will improve both the quantity and quality of sweetpotato production in Africa.

“…The main expenses include land and rent, seed and planting material, labor, fertilizers and inputs, irrigation, machinery and equipment, storage and packaging, nutritional analysis, pest and disease analysis, quality analysis, shelf life and storage analysis, and allergen analysis. Farmers should consult a reputable analytical laboratory and obtain a detailed quote to get an accurate cost estimation [154][155][156][157][158][159]. They should also consider market research, transportation, and marketing expenses.…”

“…For centuries, the sweet potato has been a fundamental part of the human diet and is still an important food for underdeveloped countries today [3,4]. Interestingly, sweet potatoes have only become a highly consumed product recently in developed countries [4,5], even though the total production has shown a decline over the past few decades [6]. Although China, Bangladesh, and several countries on the African continent are also among the world's major producers [4,7], sweet potatoes have long been cultivated throughout the American continent since before colonial times [4]; and today, sweet potatoes are an increasingly popular vegetable in developed economies due to their health benefits [7].…”

“…China has had a prominent role in sweet potato production since the 1960s, where the sweet potato is a substitute for potatoes and is less sensitive to changes in consumer income [8]. In the U.S., sweet potato consumption has been increasing, and it is a crop consumed throughout the year [5]. Despite the popularity that this crop has gained in recent years, we know very little about the behavior of sweet potato consumers in the U.S.…”

Sweet potatoes have become increasingly popular among consumers due to their health benefits, and, as a result, sweet potato production has been growing rapidly over the last decade in the United States. However, the industry is facing major challenges, including the risk of disease outbreaks and adverse weather events, which could potentially have a significant impact on the market. However, the economic literature on the sweet potato commodity is limited. This study models the U.S. sweet potato market price response to supply changes and derives elasticity estimates. This information is essential for understanding the sweet potato market and for simulating the impacts of potential supply shocks, given the challenges that the industry is facing. We found that prices are highly sensitive to supply. North Carolina, the largest sweet potato producer in the country, dominates the domestic market and exerts significantly larger influences on market prices than other producing states.
