Earthworm ecotoxicological assessments of pesticides used to treat seeds under tropical conditions

► The toxicity of seed dressing pesticides was tested on earthworms. ► Lower-tier laboratory tests were performed in tropical conditions. ► Only the pesticide with imidacloprid caused mortality in Eisenia andrei. ► All the tested pesticides showed negative effects in the chronic toxicity test. ► Avoidance tests were the most sensitive for the substances investigated in the study.
