Sensitivity of <i>Phakopsora pachyrhizi</i> towards quinone‐outside‐inhibitors and demethylation‐inhibitors, and corresponding resistance mechanisms

Abstract

The G143A mutation is thought to result in significant as well as stable resistance factors towards QoIs, while other mutations play only a minor role. Since G143A development is prevented in Phakopsora pachyhrizi, a stable control of soybean rust with QoIs in future is rather likely. In contrast, a shifting in sensitivity towards DMIs has been observed, which is due to multiple independent mechanisms.
