Fenhexamid (Ref: KBR 2738)
Last updated: 27/11/2019
(Also known as: TM-402; fenhexamide)

SUMMARY
Fenhexamid is a foliar fungicide that has approval for use in the EU. It has a low aqueous solubility, a low risk of leaching to groundwater and is relatively volatile. It is not persistent in soil or aquatic systems. It has a low mammalian toxicity and these is a slight concern regarding its potential to bioaccumulate. No serious human health risks have been identified. It is moderately toxic to birds, most aquatic organisms and earthworms. The risk to honeybees is low.
GENERAL INFORMATION
