SUMMARY

Cyprodinil is a systemic, broad-spectrum fungicide that has approval for use in the EU. It has a low solubility, is unlikely to leach to groundwater and is volatile. It soils it is moderately persistent in water systems its persistent depends upon local conditions and it is likely to degrade quickly in daylight. It is moderately toxic to mammals and their is some concern that it may bioaccumulate. Whilst it is a recognised irritant no serious human health concerns have been identified. It is moderately toxic to birds, most aquatic organisms and earthworms. It is not considered toxic to honeybees.
