Methiocarb is a carbamate pesticide (an acetylcholinesterase inhibitor) which is used as an insecticide,[1][2] bird repellent,[3] acaricide[2] and molluscicide[2] since the 1960s. Methiocarb has contact and stomach action on mites and neurotoxic effects on molluscs. Seeds treated with methiocarb also affect birds. Other names for methiocarb are mesurol[4] and mercaptodimethur.
Due to its toxicity, methiocarb approval as a plant protection product has been withdrawn by the EU effective 2020.[5]
