Assessing the efficacy of hermetic storage bags against woven polypropylene bags by farmers in Ghana for maize grain storage

The main insects that deteriorate stored maize grain in the tropics are maize weevils (Sitophilus zeamais). S. zeamais can cause significant post-harvest losses (PHL) in maize during storage. The objective of this study was to help farmers in Ghana appreciate and understand the benefits of using GrainPro bags compared to woven polypropylene bags (WPB) for storing maize grain. Eight farmers participated in the study,...
