Last updated: 14/01/2023
(Also known as: butilate)
Butylate is a thiocarbamate herbicide. It has a low aqueous solubility and is highly volatile. It may be persistent in soil and water systems depending on local conditions. Butylate tends to have a moderate to low toxicity to biodiverrsity.It has a low toxicity if ingested and is a potenrial skin irritant.
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.
