Data from 36 fungicide trials on grape downy mildew across Europe 2012-2019
Description
The data set comprises records of disease incidence and yield from untreated and treated plots.
The data is provided as both a tab-separated text file and a binary R data file. The R files provides code to read and plot the data. The plot produced is also provided as a PNG file.
The field trials were conducted by BASF, Germany.
Details
The PlantPart column refers to leaves (LEAF), inflorescences (RACEME) and grape clusters (FRUIT). The disease (GDM) was assessed by two methods (Method column), designated P%FREQ and P%INF:
• P%INF: Intensity of attack was obtained as a visual estimation of the percentage of each plant part (leaf, raceme or grape cluster) affected by disease.
• P%FREQ: Frequency of attack was obtained as the number of infected plant parts (leaf, raceme or grape cluster). The frequency was expressed as a percentage of the number sampled.
