Grape Downy Mildew Fungicide Trial Data from Europe, 2012-2019

36 field trials conducted by BASF across Europe from 2012 to 2019 record disease incidence and yield in untreated and treated grape plots. The dataset includes disease assessments on leaves, inflorescences, and grape clusters using two distinct visual estimation methods. Niels Holst of Aarhus University provides the data in tabular formats with accompanying R code for reading and plotting.

Use Cases

• Modeling fungicide efficacy based on disease incidence and yield data from treated plots.
• Comparing disease assessment methods (P%INF vs. P%FREQ) for different grape plant parts.
• Analyzing temporal and spatial patterns of grape downy mildew severity across European trials.
• Training predictive models for crop loss using historical disease and yield records.

Strengths

• Data from 36 distinct field trials provides a multi-year experimental basis.
• Disease was assessed on three specific plant parts (leaves, inflorescences, grape clusters) using two defined methods.
• Includes both raw data files and reproducible R code for analysis and visualization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Geographic coverage within Europe is not specified beyond the continent name.
