Penflufen
Penflufen is a fungicide which was produced and patented by Bayer AG in 2006 and is used for crop protection from fungi. Penflufen is a pyrazole-amide based succinate-dehydrogenase inhibitor, which blocks the electron transport at complex II in the mitochondrial respiration chain. The European Chemical Agency has also approved the use of penflufen in wood preservation despite labelling it a suspected carcinogen.
