On-farm trial with a total of 32 farmers in eight villages of Naivasha and Nakuru areas of Kenya was conducted between December 2013 and September 2014 to evaluate hermetic grain storage technologies under farmers' management conditions. The storage technologies evaluated were metal silo and SuperGrain IV-R bag alongside the standard woven polypropylene bag with or without Actellic super dust. Moisture content, insect population, grain discoloration, and weight loss were analyzed 90, 180, and 270 d after storage. Grain moisture content remained stable over the storage period. Both metal silo and SuperGrain IV-R bag suppressed insect population, prevented grain loss and cross-infestation of insects from the surrounding environment. On the contrary, polypropylene bags allowed rapid build up of insect population and re-infestation from the surrounding environment. Grain weight losses were 1.5% in the metal silo and 1.8% in the SuperGrain IV-R bags compared to 32% in the polypropylene bags without Actellic Super dust, 270 d after storage. The present study, therefore, demonstrates that storing grains either in metal silo or SuperGrain IV-R bags would benefit farmers in reducing grain losses and improving quality. The study was of great interest to the farmers, grain storage scientists, and food security experts.
2013年12月至2014年9月期间，在肯尼亚奈瓦沙和纳库鲁地区的8个村庄对32位农民进行了田间试验，以评估农民管理条件下的密闭式谷物储存技术。所评估的储存技术包括金属筒仓和SuperGrain IV - R袋，以及带有或不带有Actellic超级粉剂的标准编织聚丙烯袋。在储存90天、180天和270天后，分析了谷物的水分含量、害虫数量、谷物变色情况和重量损失。在整个储存期间，谷物水分含量保持稳定。金属筒仓和SuperGrain IV - R袋都抑制了害虫数量，防止了谷物损失以及来自周围环境的害虫交叉感染。相反，聚丙烯袋使害虫数量迅速增加，并遭受来自周围环境的再次感染。储存270天后，金属筒仓中的谷物重量损失为1.5%，SuperGrain IV - R袋中的为1.8%，而没有Actellic超级粉剂的聚丙烯袋中的谷物重量损失为32%。因此，本研究表明，将谷物储存在金属筒仓或SuperGrain IV - R袋中对农民减少谷物损失和提高质量有益。该研究引起了农民、谷物储存科学家和粮食安全专家的极大兴趣。
