Evaluations of the spray deposits are used in research as a tool to develop and improve the techniques of plant protection product application. In this way, our aim was to correlate the syrup deposition in water sensitive paper with the deposition on glass slides in order to analyze the applications flights from pesticides. The experiment consisted of four applications being held in Recanto in the municipality of Sidrolândia-MS and one in Savannah Farm in municipality of Chapadão do Céu-GO. In the first three applications, the syrup was made by insecticide Curbix 200 SC and fourth application, the insecticide ENGEO Pleno. In both assays, quantification of deposits was taken with Brilliant Blue dye. The water sensitive paper was analyzed using the software DropScan® (Leon Systems), for the variables: coverage (%) drops density (drops cm-2), volume diameter (DV0,1; DV0,5 and DV0,9) and median diameter (NMD). The spray deposition data in the blades were subjected to Pearson correlation analysis with the results of the deposition variation coefficient coverage of drops, density and quantitative deposition estimated by calculating the volumes of the droplets based on the diameters provided by the software (DMN, DV0,1, and DV0,5 DV0,9), which were multiplied by the density of droplets in the water sensitive paper. Correlations between the parameters provided directly by DropScan (coverage and density of drops) and analysis of the deposition on the blades did not provide a set of robust data that provided security for the use of all water sensitive paper + software as an alternative form of assessment spraying, in direct comparison with the method of analysis of the deposition on the blades. In two of the applications evaluated, ...
