Technical Platform on the Measurement and Reduction of Food Loss and Waste

In-farm comparison trial conducted by HELVETAS-GPLP in partnership with IITA Tanzania

The effectiveness of different storage technologies for maize under conditions of smallholder farmers were tested in Dodoma and Manyara regions of central Tanzania. Seven storage methods including the use of different hermetic storage containers (metal silos and plastic barrels with and without fumigation with phostoxin, PICS bags) and non-hermetic polypropylene (PP) bags combined with insecticide treatment (ZeroFly® bags with yarn treated with Deltamethrin and maize grain treated with Actellic Super) were tested. The storage methods were compared with traditional storage of untreated maize in polypropylene bags (PP bags). The study was conducted in two villages per region and it involved five farmers per village (total 20 replications). The dominant insect pests identified in the stored grains were the Maize weevil (Sitophilus zeamais) and the Red flour beetle (Tribolium castaneum). The hermetic storage and use of insecticides were effective in controlling insect population during storage. However, the insecticide-treatment of polypropylene yarn (ZeroFly®) did not control insect population under farmers’ management.
