Clodinafop propargyl (Ref: CGA 184927)
Last updated: 21/08/2024
(Also known as: clodinafoppropargyl)

SUMMARY
Clodinafop-propargyl is a commonly used herbicide. It has a low aqueous solubility and is not volatile. It tends not to be environmentally persistent and is not expected to leach to groundwater. It is moderately toxic to most biodiversity. It has a moderate mammalian toxicity and is a possible carcinogen. It is also a skin, eye and respiratory irritant.
