The data set consists of the data collected from litterature for a meta-analysis. It contains the results of 16 trials conducted in different orchards located in different regions around the world. Each trial has two treatments: an untreated part (the control, X = Fung_Gp = 0) and a part treated with a fungicide (X = Fung_Gp = 1). In each treatment, 300 to 2000 fruits were observed, and the number of diseased fruits was counted.
