Mode of Action and uses

Fosethyl aluminium is an organic phosphate compound used as a systemic fungicide with protective activity. It is rapidly absorbed through the plant leaves or roots, with translocation both up and down inside the plant.

It acts by inhibiting spore germination and penetration into the plant, and by blocking mycelial growth and spore production. Also enhances the plant’s own natural defense systems against diseases. Mode of action is multi-site.

Fosetyl aluminum has preventive and curative properties against diseases caused by Oomycetes. It is used to control diseases e.g. Phytophthora, Pythium, Plasmopara, Bremia spp., etc. on a variety of crops, including vines, fruits (citrus, stone fruits and pome fruits), berries, vegetables and ornamentals.
