Protection Efficacy of Antibacterial Strains against Fire Blight Caused by Erwinia amylovora on Apple Blossom.
Article in The plant pathology journal, 2024. 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
Fire blight caused by Erwinia amylovora is one of the destructive diseases in the family of Rosaceae plants, including apple and pear, in the world. Since the first report in 2015, the number of infected farms and area steadily increased in Korea. In case of eradication failure against this disease, protection strategies using both chemicals and biocontrol agents should be established. In this study, to select an effective antibacterial agent against fire blight on apple trees, four bacterial strains isolated from Jeju Island were investigated. Among the bacterial strains, Bacillus circulans BRH433-2 showed bactericidal effects against E. amylovora Ea385 forming inhibition zone on an artificial medium. The other bacterial strains such as Pseudomonas fluorescens THJ609-3, Micrococcus luteus TRK2-2 and P. fluorescens TRH415-2 showed bacteriostatic activity preventing growth of E. amylovora Ea385 in shaken cultures as well as on detached apple blossoms inoculated with E. amylovora Ea385, as measured with quantitative PCR. Bio-tests on detached blossoms showed that the treatment with all bacterial strains caused strong suppression of bacterial ooze formation, indicating inhibition of disease incidence of fire blight, which was similar to blossoms treated with streptomycin sulfate. Therefore, it was suggested that these bacterial strains may be useful in organic apple orchards to control fire blight where chemical use is limited.
