Dalapon is a selective herbicide used to control perennial grasses. The major use of dalapon is on food crops including sugarcane and sugar beets.[1]

Its use is no longer authorized in France.[2]

The National Institute for Occupational Safety and Health in the United States has identified it as a potential workplace hazard. The recommended time-weighted average exposure limit is 6 milligrams per cubic meter during a 10-hour workday.[3]

Exposure to dalapon affects the eyes, central nervous system, digestive system, respiratory system, and skin. Dalapon can be absorbed through inhalation, eye contact, skin contact, or by ingesting it. The symptoms of dalapon exposure include eye irritation, central nervous system depression, bradycardia, vomiting, diarrhea, loss of appetite, fatigue, burn, upper respiratory irritation, and skin irritation. First aid measures for exposure include artificial respiration, immediate eye irrigation, and immediate washing with water. Immediate medical attention should be sought if dalapon is ingested.[3]
