Description and Uses

Foramsulfuron is a sulfonylurea selective, post-emergence herbicide for grass and broadleaved weed control. It is highly soluble in water and has a low volatility. It is not normally persistent in soil or water systems but does have the potential to leach to groundwater depending on local conditions. There are no serious concerns about its toxicity to humans. Toxicity to biodiversity is generally classified as low to moderate.

Herbicide.
