SUMMARY

Dichlofluanid is a fungicide without regulatory approval for use in the EU. It has a low aqueous solubility and is volatile and, based on its chemical properties, it is unlikely to leach to groundwater. It is not persistent in most soil or aquatic systems. Dichlofluanid has a low mammalian toxicity but, with the exception of birds, is moderate to highly toxic for most biodiversity including aquatic life, bees and worms.
