Trifloxysulfuron-sodium (Ref: CGA 362622)
Last updated: 23/01/2023
(Also known as: CGA 362622)
Trifloxysulfuron-sodium is a post-emergence herbicide. It has a high aqueous solubility, is relatively volatile and, based on its chemical properties, is mobile and may leach to groundwater in some situations. It is moderately persistent in soil systems but is generally non-persistent in aquatic systems. It has a low mammalian toxicity and has a high potential to bioaccumulate. It is a skin and eye irritant. It is moderately toxic to birds, honey bees and earthworms but is less toxic to fish and daphnia. However, it is very toxic to aquatic plants and algae.
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.
