The sensitivity of Venturia inaequalis field isolates to inhibitors of the cytochrome bc1 complex at the Qo site (QoIs) was characterised at the molecular, biochemical and physiological level, and compared to other respiration inhibitors.
Cross-resistance was observed among QoIs such as trifloxystrobin, azoxystrobin, famoxadone, strobilurin B and myxothiazol.

Famoxadone binding to the Qo site decreases k1 to 5400 s-1, indicating that a conformational change on the surface of cyt b decreases the rate of release of the ISP from cyt b.

In this work, it is shown that, in addition to myxothiazol, a number of other proximal Q (o) inhibitors [including (E)-beta-methoxyacrylate-stilbene, mucidin, and famoxadone] also induce O (2)(*)(-) production in the isolated yeast cyt bc (1) complex, at approximately 50% of the V (max) observed in the presence of antimycin A.
