SUMMARY |
Trifloxysulfuron-sodium is a post-emergence herbicide without EU regulatory approval for use. 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. |
