Abstract

A 66-year-old man ingested 200 mL of Dexol Industries Weed and Grass Killer Concentrate (Torrance, CA), which contains 1.84% diquat dibromide, a herbicide structurally similar to paraquat. He remained asymptomatic for 8 hours, and then a sore throat and vomiting developed. Twenty hours after ingestion, esophagitis, mucositis, epiglottitis, and acute renal failure developed, from which he slowly recovered. This is the first report of systemic diquat toxicity from ingestion of a diluted diquat solution.
