A survey in the Ejura-Sekyedumasi municipality of Ghana's Ashanti Region assessed the use of Cedrela odorata leaves for storing maize. Fifty farmers from five maize-producing communities were sampled. Maize was either shelled and bagged or unshelled and stored in rooms or barns. Field pests included weevils, termites, and fall armyworms. Most farmers (52%) stored maize for up to three months before sale or consumption. Seventy percent treated maize before storage, with 52% using Cedrela odorata leaves and 8% using phostozin. Farmers considered Cedrela odorata leaves safe, as they are used to treat malaria, unlike phostozin, which is highly poisonous. Three kilograms of leaves were used for 100 kilograms of maize, spread at the bottom, middle, and top of the sack and tightly sewn. Farmers reported that the leaves were effective against storage weevils for up to three months but recommended empirical determination of efficacy and safety.
