The objective of this work was to evaluate the spectrum of droplets and syrup deposition of motorized costal atomizer, using additives in spraying solution. For this purpose geostatistical approach was applied. The treatments such as water (witness) and different additives (mineral oil, siliconized polymer and ethoxylated nonylphenol) were applied. Just before application, collectors (glass plates and hydrosensitive labels) were distributed at seven distances from the center of the spray circumference with different radius (3.0, 6.0, 9.0, 12.0, 15.0, 18.0 and 20.0 m), in the directions of the cardinal and collateral points, totaling 56 sample points. The deposition parameters, volumetric median diameter (VMD), relative amplitude (RA) and coverage were evaluated by means of aqueous solution (spray liquids + dye) to verify deposition by spectrophotometry and hydrosensitive paper label for the spectrum of drops. Descriptive analysis of the data was performed and geostatistics used as a tool for the analysis of spatial variability. The values for non-sampled locations were estimated using the ordinary kriging interpolation method. It allowed mapping that defined the application zones for the calculation of drift. The results showed that the VMD of the droplets was 136 μm. The application maps showed that there was a drift of 71.50% of the volume of syrup applied. The geostatistical tool made it possible to evaluate the droplet and deposition spectrum by means of the application maps. The proposed climatic recommendations for the application of agricultural pesticides do not apply to cost atomizers.
