Dicarboximide (or dicarboxamide) fungicides are a family of agricultural fungicides that include vinclozolin, iprodione, and procymidone. Dicarboximides are believed to inhibit triglyceride biosynthesis in sclerotia-forming fungi, including Botrytis cinerea. These fungicides turn into 3,5-dichloroaniline in soil rapidly. Repeated use of dicarboximides over several years reduce their effectiveness. Resistance has developed against all dicarboximides in many plant species, including vines, strawberries and protected crops, and are recommended to be used in conjunction with other fungicides.
