First European Xanthomonas Bacteriophage Cocktail for Pepper Bacterial Spot Control

A 2026 study by Elena G. Biosca describes the development of a lytic bacteriophage cocktail effective against Xanthomonas euvesicatoria pv. euvesicatoria (Xee), the main causal agent of bacterial spot in pepper plants. The research includes genomic analysis of five phages and in vitro and in planta efficacy testing of a three-phage cocktail. The dataset, shared on figshare, comprises a 6.0 MB document detailing the isolation, characterization, and application of these phages from pepper plots in Spain.

Use Cases

• Training models for biocontrol agent efficacy based on in vitro co-culture results described in the study
• Analyzing phage stability for field application based on temperature and pH condition testing mentioned in the description
• Studying genomic features of lytic bacteriophages belonging to the Beograduvirus genus as detailed in the taxonomic analysis

Strengths

• Documented efficacy of a three-phage cocktail showing significantly better pathogen control than single-phage treatments in co-culture experiments
• Phages were isolated from pepper plots in two distant regions of Spain, suggesting potential environmental relevance
• Phages remained stable across a range of temperatures and pH conditions relevant to field application

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The primary data format is a DOCX document, which may require parsing to extract structured data for analysis
