Description and Uses
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, honeybees and earthworms but is less toxic to fish and daphnia. However, it is very toxic to aquatic plants and algae.
Used as a herbicide.
