Butroxydim (Ref: ICIA0500)
Last updated: 15/06/2023
(Not known by any other names)
Butroxydim is an obsolete herbicide. It has a low aqueous solubility, is relatively volatile and, based on its chemical properties, is non-mobile and would not be expected to leach to groundwater. It is generally non-persistent in soil systems but may persist in aquatic systems under certain conditions. It is not generally susceptible to hydrolysis. It has a moderate mammalian toxicity and has a high potential to bioaccumulate. It is moderately toxic to most aquatic species, birds and earthworms but relatively non-toxic to honeybees.
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.
