• Propanoic acid, 2-(3-chlorophenoxy)-: INACTIVE
• Chlorophenoxy herbicides are applied alone or as mixtures with other herbicides, in solutions, dispersions, or emulsions in water &/or oil, using equipment that produces large droplets to avoid spray drift. /Chlorophenoxy herbicides/
• New Zealand: The spraying of phenoxyherbicides is restricted within prescribed distances of vineyards. /Phenoxyherbicides/
• The chlorophenoxy compounds are absorbed across the gut wall, lung, and skin. They are not significantly fat storable. Excretion occurs almost entirely by way of the urine. /Chlorophenoxy herbicides/
