Chemical composition and antifungal activity of plant extracts traditionally used in organic and biodynamic farming.
Article in Environmental science and pollution research international, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Five plant extracts traditionally used in organic and biodynamic farming for pest control and antifungal (downy mildew) disease management were selected after a farmer survey and analyzed for their chemical composition in LC-PDA-MS-MS and using adapted analytical method from food chemistry for determination of class of component (e.g., protein, sugar, lipids…). Their antifungal activity against Penicillium expansum, Botrytis cinerea, Botrytis allii, brown rot causing agents (Monilinia laxa and Monilinia fructigena), and grape downy mildew (Plasmopara viticola) was examined in vitro. White willow (Salix alba) and absinthe (Artemisia absinthium) ethanolic extracts were found to be the most effective in particular against Plasmopara viticola, with a total inhibition of spores germination when applied at 1000 mg/L. These extracts also showed a relatively low toxicity during preliminary ecotoxicological assays on Daphnia pulex. Extract from the bark of white willow contained some flavonoids, especially flavanones (eriodyctiol and derivates) and flavanols (catechins and derivates), as major compounds, whereas absinthe extract was rich in O-methylated flavanols and hydroxycinnamic acids. Thujone content in this extract was also determined by external calibration in GC-MS analysis, and its value was 0.004% dry extract.
