Discovery of new PSII inhibitors: systematic investigation for herbicidal activity screening, properties, and mode of action.
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 1 paper.
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
backgroundThe research focused on developing effective photosystem II (PSII) inhibiting triazine-derived herbicidal compounds from the internal chemical library. Initially, the compounds were screened for their herbicidal activity using Spirodela polyrhiza (SPIPO) assays. Subsequently, compounds with stronger activity were synthesized on a gram scale and further investigated for their phytotoxicity, mobility, and mode of action.
resultsIn the SPIPO screenings, two compounds, K-31706 and K-31487, showed superior efficacy at concentrations exceeding 0.4 μm, surpassing the commonly used PSII inhibition herbicide, atrazine. Both compounds showed promising performance, especially in pre-emergence applications under greenhouse conditions, with the application rate causing 50% biomass reduction below 100 g a.i. ha
conclusionOverall, K-31706 and K-31487 are nonselective PSII inhibitors that block the electron transport in PSII, positioning them as potentially useful active ingredients for further investigation. © 2025 The Author(s).
