Description and Uses

Ethoxysulfuron is a herbicide used for broadleaved weed and sedge control in a range of crops including cereals and rice. It has a high aqueous solubility and a low volatility. It is not expected to be persistent is soil systems but, under certain conditions may be persistent in water bodies. Ecotoxicity is low for most species, the main exception is algae and aquatic plants. Human toxicity is also low and no chronic risks have been identified.

Herbicide.
