Flufenacet (Ref: FOE 5043)
Last updated: 22/08/2024
(Also known as: fluthiamide; fluofenacet ; thiafluamide)

SUMMARY
Flufenacet is a selective herbicide. It is moderately soluble in water, is not highly volatile but may, under certain conditions, be persistent in soil and water/sediment systems. It is moderately toxic to humans via the oral route and is considered to be a skin sensitiser. With the exception of honeybees where the toxicity is low, flufenacet is either moderately or highly toxic to most fauna and flora.
