Its mode of action is to inhibit transport-associated phosphorylation of glucose, which reduces mycelial growth rate.[1] Fludioxonil is used against Fusarium, Rhizoctonia, Alternaria and Botrytis cinerea.

Brand names include seed treatments: Celest, Agri Star Fludioxonil 41 ST, Dyna-shield Fludioxonil, Maxim 4 FS, and Spirato 480 FS, as well as foliar applications: Switch (fludioxonil + cyprodinil).[2]
