Fluopicolide is a systemic and translaminar fungicide belonging to the acylpicolide chemical class, developed specifically for controlling oomycete pathogens such as Phytophthora, Plasmopara, Pythium, and Peronospora species. It is widely used in agriculture for protecting vegetables, potatoes, grapes, cucurbits, ornamentals, turf, and other high-value crops.
Fluopicolide exhibits a novel mode of action, targeting the spectrin-like proteins in oomycete pathogens, affecting their cytoskeleton structure, cell stability, motility, and development. This unique mechanism provides strong anti-sporulation, preventive, and protective activity against aggressive plant diseases such as downy mildew and late blight.
