Insights into ALS-inhibiting herbicide resistance in Poa annua in an arable cropping system.
Article in Pest management science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDependence on a single herbicide type to control a broad-spectrum of weeds has resulted in cases of resistance to acetolactate synthase (ALS) inhibitors in weeds normally considered lower priority such as Poa annua, being recorded in winter wheat fields in Ireland. This study characterizes resistance to ALS-inhibiting sulfonylureas (SU), sulfonylamino-carbonyl-triazolinones (SCT) and triazolopyrimidine (TP) herbicides in five resistance-suspect populations (POAAN-R1 to POAAN-R5).
resultsVariability in cross-resistance levels were noted in the POAAN-R populations, correlating with target-site mutations and specific amino acid substitutions. Mutations Pro-197-Thr in POAAN-R1, Pro-197-Thr + Trp-574-Leu in POAAN-R4, and Trp-574-Leu in POAAN-R5 confer high levels of resistance to SU, SU + SCT and TP herbicides (GR
conclusionPro-197-Thr and/or Pro-197-Gln, as well as the combination of Pro-197-Thr + Trp-574-Leu were identified for the first time in P. annua in this study. As cultural/non-chemical management of P. annua is challenging, the primary control in cereal crops will likely be the use of non-ALS herbicide modes of action, including the application of pre-emergence or autumn residual-type herbicides. © 2025 The Author(s).
