Poa annua becomes the first weed to evolve resistance to indaziflam applied preemergence and early-postemergence.
Article in Pest management science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHerbicide resistance evolution is a major challenge in agriculture. Poa annua L., a globally distributed and genetically diverse weed, has repeatedly evolved resistance to multiple herbicide sites of action due to its genetic plasticity and rapid life cycle. Indaziflam is widely used for P. annua control in several agroecosystems, with reports of postemergence resistance and a few confirmed cases of resistance to preemergence application. This study investigated suspected resistance to indaziflam in P. annua accessions from Oregon hazelnut orchards.
resultsWhole-plant dose-response assays confirmed indaziflam resistance in eight accessions ranging from 2.5- to 51-fold relative to susceptible accessions, which had a lethal dose to 50% of the accession (LD
conclusionThis study provides the first confirmed cases of field-evolved resistance to indaziflam applied both preemergence and early-postemergence in P. annua. Resistance was most severe under cooler temperatures and postemergence use, highlighting environmental and developmental effects on indaziflam activity. © 2025 The Author(s).
