Toxicology

Lactofen is slightly to non-toxic to humans when ingested or inhaled. It can cause skin irritation including reddening, swelling and possibly corrosive burns. It is a severe eye irritant and can cause permanent damage to eyes when there is sufficient exposure. It was found to be practically non-toxic to the species of bird that were studied.Herbicide Handbook of the Weed Science Society of America. 1989. Sixth edition. Champaign, IL Toxicity to fish and other aquatic organisms varied and it was eliminated in fish within fourteen days. It is of low toxicity to bees. Lactofen has a very low solubility in water and is not expected to contaminate surface waters. It binds tightly to soil and is then broken down in between one and seven days.US Environmental Protection Agency. 1987. Fact Sheet Number 128: Lactofen. Washington, DC.
