This work aimed to evaluate the pesticide spraying in no tillage system using statistical quality and GIS tools. The data were collected in a farm Paraná State, Brazil. Two indicators were considered: drop coverage percentage and drop density. Tools from descriptive statistics, quality control and GIS were used in the results evaluation. The spraying process presented irregularity and high variability, demanding improvement. However, considering the characteristics of the applied pesticides (systemics), the operation could be considered as reasonable. The association of the control chart, histogram and GIS is a tool which allowed the process characterization to be done.
