What is Cyprodinil?

Plain description, key identifiers and synonyms

Cyprodinil is a member of the class of aminopyrimidine that is N-phenylpyrimidin-2-amine carrying additional cyclopropyl and methyl substituents at positions 4 and 6 respectively. A broad spectrum fungicide used to control a range of pathogens including Tapesia yallundae, Botrytis spp., Alternaria spp. and Rhynchospium secalis. Whilst it is a recognised irritant no serious human health concerns have been identified. It is moderately toxic to birds as well as most aquatic organisms and earthworms, but it is not considered toxic to honeybees. It has a role as a xenobiotic, an aryl hydrocarbon receptor agonist, an environmental contaminant and an antifungal agrochemical. It is an aminopyrimidine, a secondary amino compound, a member of cyclopropanes and an anilinopyrimidine fungicide.
