Sensitivity of <scp> <i>Leptosphaeria maculans</i> </scp> to <scp> Q <sub>O</sub> I </scp> fungicides in Australia
No resistance to azoxystrobin was detected in this study suggesting that Australian blackleg populations are currently sensitive to the Q<sub>O</sub>I fungicides. In vitro and in planta assays are now established for continued monitoring of populations. Lastly, an additive effect was observed when combining Q<sub>O</sub>I and demethylation inhibitor (DMI) fungicides suggesting Q<sub>O</sub>I fungicides should be released only in combination with other actives to increase fungicide efficacy. © 2025 Society of Chemical Industry.
