In Niger, considerable damage is recorded on seed legumes during their storage. For this, chemicals are used for the preservation of these foodstuffs. The objective of this study is to understand the use of storage insecticides against pests in Cowpea. A survey was carried out using structured sowing questionnaires with 404 producer heads of households in 16 target villages.The study shows that 91.8% of operators use insecticides for the conservation of cowpeas, mainly approved products (76%), namely Phostoxin (55.94%), Justoxin (16.58%), Rambo (0, 50%), Lamda super 2.5 EC (1.73%), Calthio (0.99%) and non-approved products (16%), namely Executor (5.20%) and Superdelvap (10.89%). This use of chemicals varies depending on the Regions (Dosso, Tillaberi, Maradi).Thus, the study also showed that 65.1% of households use phostoxin in the Dosso region compared to 29.5% and 63% respectively in the Maradi and Tillabéri regions. Up to 40% of producer households use super delvap, which is an unauthorized product to prevent damage of [Callosobruchus maculatus (Fab.)] From Cowpea at Maradi.
