Utilization of biological insecticides for the protection of stored yam chips by Vernier, Philippe, Georgen, G., Dossou, R., Letourmy, P., Chaume, J.

“…The level of protection provided by various biological products derived from neem (Azadirachta indica) and Crotalaria caricea was compared with that of a synthetic pesticide, Sofagrain™(1.5% deltamethrin + 0.5% pirimiphos-methyl), a reference chemical for stored products in Benin. Insect damage was assessed over a period of 10 months in the store room. …”

Yield loss of Oryza glaberrima caused by grain shattering under rainfed upland conditions by Montcho, D., Futakuchi, K., Agbangla, C., Fofana, M., Dieng, I.

“…Yields of 21 O. glaberrima accessions were evaluated alongside four O. sativa check varieties under two conditions in which panicles were both covered by paper sacks to avoid grain shattering (potential yield plot) and also not covered (control plot) in a rainfed upland field of Benin in 2010 and 2011. Average potential yields of O. glaberrima with panicles covered were 2.42 and 3.65 t ha-1 in 2010 and 2011, respectively, while those of O. sativa were respectively 2.99 and 3.49 t ha-1. …”
