مستخلص: | Background: Fenpicoxamid is a recently developed fungicide belonging to the quinone inside inhibitor (QiI) group. This is the first fungicide within this group to be active against the Zymoseptoria tritici, which causes Septoria tritici blotch on wheat. The occurrence of pre-existing resistance mechanisms was monitored, using sensitivity assays and Illumina sequencing, in Z. tritici populations sampled in multiple European countries before the introduction of fenpicoxamid. Results: Although differences in sensitivity to all three fungicides tested (fenpicoxamid, fentin chloride and pyraclostrobin) existed between the isolate collections, no alterations associated with QiI resistance were detected. Among the isolates, a range in sensitivity to fenpicoxamid was observed (ratio between most sensitive/least sensitive = 53.1), with differences between the most extreme isolates when tested in planta following limited fenpicoxamid treatment. Sensitivity assays using fentin chloride suggest some of the observed differences in fenpicoxamid sensitivity are associated with multi-drug resistance. Detailed monitoring of the wider European population using Illumina-based partial sequencing of the Z. tritici also only detected the presence of G143A, with differences in frequencies of this alteration observed across the region. Conclusions: This study provides a baseline sensitivity for European Z. tritici populations to fenpicoxamid. Target-site resistance appears to be limited or non-existing in European Z. tritici populations prior to the introduction of fenpicoxamid. Non-target site resistance mechanisms exist, but their impact in the field is predicted to be limited. © 2022 The Authors.
