SUMMARY
Azaconazole is a Sterol biosynthesis inhibitor with fungicidal action that does not have EU approval for use. It is moderately soluble in water, relatively volatile and may be persistent in aquatic systems. Azaconazole is moderately toxic to mammals but is not expected to bioaccumulate. It is moderately toxic to birds, fish and aquatic invertebrates. GENERAL INFORMATION
