Bensulide (Ref: R 4461)
Last updated: 01/09/2023
(Also known as: benzulfide)
Bensulide is an organophosphate herbicide. It has a low aqueous solubility, miscible with most common organic solvents and shows a low to moderate volatility. It may persist in soil and water systems under certain conditions. There is a low risk of leaching to groundwater. Bensulide has a moderate toxicity to humans as well as being a cholinesterase inhibitor and a neurotoxin. It is moderately toxic to birds, fish, aquatic plants and 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.
