Benfuresate (Ref: NC 20484)
Last updated: 13/01/2023
(Not known by any other names)
Benfuresate is a post-emergence herbicide. It has a moderate aqueous solubility and is relatively volatile. It is not persistent in soil systems but not normally persistent in water. It has a low mammalian toxicity and a low potential for bioaccumulation. It is relatively non toxic to birds but moderately toxic to honeybees and most aquatic organisms.
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
