(Also known as: acifluorofen; acifluorfen metabolite; lactofen metabolite; PPG 847; carbofluorfen) |
SUMMARY |
Acifluorfen is a post-emergence herbicide, usually used as the sodium salt. It is highly soluble in water, with a low vapour pressure and may be moderately persistent in soils and water depending upon conditions. Based on its chemical properties it has a high potential for leaching to groundwater. It has a low to moderate toxicity to most biodiversity. It is not highly toxic to human but is known to be a skin and eye irritant. |
