text: These include findings that (1) PICS triple-layer storage bags can be reused for two or more storage seasons by African farmers without diminution of effectiveness in protecting stored cowpea grain while reducing the effective economic cost (2) many small-holder farmers prefer bags that hold 100 kg of cowpea grain over those that contain 50 kg (3) laboratory studies showed that 100 kg bags preserved grain as well as did 50 kg bags but 100 kg bags had the advantage of lower cost per unit of grain stored (4) grain stored on farms showed the same changes in gas composition within the bags -- drops in oxygen levels with concomitant rises in carbon dioxide -- as has been documented from laboratory studies (5) grain stored on farms was well preserved against losses to cowpea bruchids; damage levels after months of storage was unchanged from that observed when the grain was put into storage.
