The majority of methods, which evaluates the pulverization in agriculture, besides being subjective it has difficult performance. With the development of the computer science, there is a possibility of processing analyses in great number and in a no subjective way. The objective of this work was to evaluate if the Conta-Gotas software can be used to study the effect of the drop size, the wind and the orientation of the spray nozzles in willing targets spraying coverage. From the top to the bottom application, the obtained results for the following variables as covering and droplets cm-2 can be considered as expected and they show that, in spite of being simple, the method has sensibility to detect differences. Considering the top to the bottom and vice-versa spray nozzles orientation the results show how the simple inversion provokes alterations in the behavior of the pulverization drops in relation to its size and effect of the wind. The conta-gotas software is appropriate to be used in similar evaluations like the ones done in this work.
