This is a list of fungicides. These are chemical compounds which have been registered as agricultural fungicides. The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users.[1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials,[2] including their brand names and the countries and dates where and when they have been introduced.[3] The industry-sponsored Fungicide Resistance Action Committee (FRAC) advises on the use of fungicides in crop protection and classifies the available compounds according to their chemical structures and mechanism of action so as to manage the risks of pesticide resistance developing.[4] The 2024 FRAC poster of fungicides includes the majority of chemicals listed below.[5]
