Sulfosulfuron (Ref: MON 37500)
Last updated: 05/03/2024
(Also known as: TKM 19)

SUMMARY
A sulfonylurea herbicide approved for use in the European Union and in some other countries. Sulfosulfuron is highly soluble in water, is semi-volatile and is mobile with a high potential for leaching to groundwater based on its physico-chemical properties. It is considered to be moderately persistent in soils and can also be persistent in water systems depending upon conditions. It may bioaccumulate but has a low mammalian toxicity. It is moderately toxic to fish, algae, earthworms and honeybees but less so to birds and aquatic invertebrates.
