“…Since the launch of the scale-up of the PICS technology in the Sahel 12 years ago, it remains the most commercially available hermetic bag to farmers in several countries [52]. Several projects and initiatives have promoted several brands of hermetic bags in Kenya to reduce storage losses through prize competition [23,53].…”

Several postharvest technologies are currently being commercialized to help smallholder farmers in sub-Saharan Africa reduce grain storage losses. We carried out a study in Northern Benin to compare the effectiveness of five technologies being sold to protect stored grain. Maize that had been naturally infested by insects was stored in four hermetic storage technologies (SuperGrainbag™, AgroZ® bag, EVAL™, and Purdue Improved Crop Storage-PICS™ bags), an insecticide impregnated bag (ZeroFly®), and a regular polypropylene (PP) woven bag as control. Oxygen levels in hermetic bags fluctuated between 0.5 ± 0.0 (v/v) and 1.0 ± 0.3 (v/v) percent during the seven months of storage. No weight loss or insect damage was observed in grain stored in any of the hermetic storage bags after seven months. However, grain stored in ZeroFly® and PP woven bags had weight losses of 6.3% and 10.3%, respectively. These results will help farmers and development agencies when making decisions to use and/or promote storage technologies to reduce postharvest grain losses.

“…Hermetic storage methods are viable chemical-free alternatives to traditional methods and pesticides used for grain storage among smallholder farmers [33,44]. They effectively control pests of stored products, maintain seed quality, improve food security, and increase the income of smallholder farmers [32,33,36,45].…”

“…They effectively control pests of stored products, maintain seed quality, improve food security, and increase the income of smallholder farmers [32,33,36,45]. Though farmers reported not having issues while using hermetic storage methods, some of the challenges associated with rigid containers such as silos and drums are cost, efficacy when not fully filled, and scalability [44,46,47]. Training and capacity-building in the use of these rigid containers may help to address some of these issues.…”

“…A recent study conducted in Chitwan, Nepal, showed that PICS bags and SuperGrainbags™ were effective at preserving stored maize [16,32]. Hermetic bags have been disseminated to millions of smallholder farmers in Africa [44]. Though there are suppliers of both PICS and SuperGrainbags™ in Nepal, the use of these technologies among farmers remains low due mostly to limited awareness and unavailability.…”

“…Only a small proportion of farmers complained about the price, which is about NPR 250 (Nepalese rupees, about USD 2.50) for a 50 kg hermetic bag. Farmers who produced enough to store seldom complained about the price of hermetic bags because they are affordable [44]. A cost-benefit analysis conducted in several districts in Nepal showed a positive gain when grains (e.g., rice) were stored in hermetic bags compared to traditional storage methods [17].…”

Farmers in Nepal lose up to one-third of stored grain to pests and diseases. This results in food insecurity and loss of income. To mitigate these losses, farmers use several approaches including pesticide applications on stored grains. We interviewed 241 farmers in Bagmati Province, Nepal, to assess the current on-farm grain storage practices and challenges to improve postharvest management. The results show that rice was the most stored crop (median 1150 kg). About half of farmers stored for at least nine months and grain was mainly used for home consumption. Grain was stored by 66.5 and 69.8% of farmers in granaries (rice) and plastic drums (legumes), respectively. Insects were the most important challenge during storage, and farmers used pesticides to control them. Farmers were more likely to use insecticide on grain (p = 0.000) if they stored rice, used traditional granaries, and had insect damage during storage. The use of improved storage methods (e.g., hermetic bags) was very low for rice (3.5%). There is a need to improve on-farm grain storage by disseminating storage innovations to address postharvest challenges in important crops such as rice.

Postharvest management is critical to attaining household food, nutrition, and income security. Hermetic grain storage bags offer an effective pesticide‐free way to protect stored grain against fungal and insect infestation. We evaluated articles indexed in the Web of Science that included experiments comparing the storage efficacy of conventional and hermetic storage bags based on grain germination rate, insect infestation, physical damage, mycotoxin contamination, and changes in weight and moisture content. Compared with grain stored in hermetic bags, grain stored in conventional bags lost 3.6‐fold more seed viability, contained 42‐fold more insects, had 11‐fold more physical damage, and lost 23‐fold more grain weight, while grain moisture levels were similar for both hermetic and conventional storage bags. Mycotoxin contamination levels were not as frequently assessed. Levels could be low in grain stored in both types of bags, or levels could be low in hermetic bags and significantly higher in conventional bags. The improved properties of grain stored in hermetic bags can increase food security and household income by providing safe storage options for maintaining seed germinability, and for consumption and/or sale when food supplies are high, or when prices are low. Hermetic bags are economically feasible for use by subsistence farmers in Sub‐Saharan Africa for grain for household consumption and for carrying‐over seed for planting in the next season. Additional studies are needed to verify the mycotoxin contamination results and to determine if there are differences in functional food characteristics, e.g. flavor and cooking properties, that have not been as comprehensively studied. © 2023 The Authors.
