Toxicological data
As far as possible and customary, SI units are used. Unless otherwise noted, the data given apply to standard conditions .

Fenamidon is a chemical compound from the imidazoline group and a fungicide developed by Rhône-Poulenc and introduced in 2001 , which is now marketed by Bayer CropScience .

Extraction and presentation

At the start of production, there were strong smelling by-products.

Effect and use

Fenamidon has the same mechanism of action as the strobilurins . The effect is based on the inhibition of complex III of the respiratory chain , the cytochrome c reductase at the Qo point. It works both protective and curative.

Admission

Fenamidon has not been approved in the EU countries since 2019, but the active ingredient is still approved in six EU member states. Plant protection products with this active ingredient are also approved in Switzerland, and broccoli has a relatively high maximum residue level of 5 milligrams of fenamidone per kilogram. Active ingredient is also sold on the Brazilian market.
