Cyclosulfamuron (Ref: BAS 710H)
Last updated: 15/03/2023
(Also known as: AC 322140; JIN-QUI)
Cyclosulfamuron is a cereal and rice herbicide. It has a low aqueous solubility, is volatile and, based on its chemical properties, is only slightly mobile and would not be expected to leach to groundwater. It is not generally persistent in soil systems. It has a low mammalian toxicity and has a high potential to bioaccumulate. It is moderately toxic to most aquatic species, birds, honey bees and earthworms.
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.
