Laboratory toxicity test and field control effect test are important experiments to evaluate the effect of pesticides on disease control. The safety of pesticide application depends on whether the pesticide residue on the fruit complies with the limits related to the good agricultural practices which were assessed by the legislative framework. In addition, many factors may affect the control effect of fungicides in the field experiment, among which one of the most important factors is the precipitation during the application process in the growing season. In this study, raw data of the laboratory toxicity of different fungicides to Colletotrichum fructicola, disease severity after treatment with different agents, the pesticide residue on the fruit after preharvest application, and the precipitation in the growing season are provided. In addition, this study also introduced the method and calculation process of raw data processing. We hope that these raw data will serve as a reference for other researchers who are studying the prevention and control of Glomerella leaf spot (GLS).
