Priaxor 7.5/15 EC is a mixture of the active substances fluxapyroxad and pyraclostrobin and has a protective and therapeutic effect. Fluxapyroxad is a fungicide with bisectal motion and preventive and therapeutic action of broad spectrum and long duration. It belongs to the chemical group of inhibitors of succinic acid dehydrogenase (SDHI). It acts as a blocker of the respiratory chain in complex II. It prevents spore germination, lengthening of the vegetative canal, mycelium growth and sporiogenesis. Pyraclostrobin interferes with cellular respiration at the Qo site of complex III of the respiratory chain, displaying apoplasty and bisectal movement. It prevents the germination of spores, the growth of mycelium and the increase of infestation.
