The aim of the research is to assess the level of soil contamination by pesticides in Djidja’s cotton area in Benin. Soil samples have been collected in nine (09) cotton fields from 15th to 19th March, 2014. The analysis has been done by gas chromatography after extraction and purification. The results show a soil contamination by glyphosate varying from 0.271 to 0.317 μg/kg, by profenofos varying from 0.109 to 0.130 μg/kg, by acetamiprid varying from 0.088 to 0.153 μg/kg and by cypermethrin varying from 0.165 to 0.190 μg/kg. A regular surpervision program must be planned to limit as possible the soil contamination by pesticides in this township.
