Grapevine Downy Mildew Susceptibility and Epidemic Data from Canopy Density Study

Giorgia Fedele's dataset investigates the effect of grapevine canopy density on leaf susceptibility to Plasmopara viticola and the development of downy mildew epidemics. The data includes results from artificial inoculation of leaf discs and periodic field assessments of disease severity, expressed as AUDPC. The dataset was last updated on 2026-04-22 and is shared under a CC-BY-4.0 license.

Use Cases

• Modeling the relationship between canopy density and leaf predisposition to Plasmopara viticola based on artificial inoculation results.
• Analyzing the progression of downy mildew epidemics in the field based on disease severity assessments.
• Investigating the complex interactions between host plant components, pathogen infection cycles, and microclimate factors mentioned in the description.

Strengths

• Dataset is based on controlled agronomic interventions including variations in bud load, fertilization, and irrigation.
• Includes both laboratory (leaf disc inoculation) and field (disease severity) experimental data.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Dataset is very small at 23.0 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
