Aminocarb (Ref: BAY 44646)	Last updated: 13/01/2023
(Also known as: ENT 25784 ; matacil)

---

SUMMARY

Aminocarb is an obsolete insecticide. It is highly soluble in water, has a low volatility and tends to be non-persistent in soil and aquatic ecosystems. Based on its chemical properties it is not expected to leach to groundwater. It is highly toxic to mammals and many animal species including pollinators.
