The fungicide application technology should provide efficient control of vegetable diseases. The objective of this study was to evaluate the deposition and the drift of fungicide sprayed in a common bean crop with different nozzles and two volumes of application. A completely randomized block design with four replications was used, in a factorial model 2 x 2: two spray nozzles (standard flat fan and hollow cone) and two spray volumes (125 and 250 L ha-1). The study of deposition was made by a tracer analysis in different positions of the crop, using spectrophotometer. The drift was evaluated using artificial targets placed outside the application area. The fungicide, with the tracer was applied three times, using a CO2 - pressurized sprayer. The results allowed the following conclusions: the flat fan and hollow cone nozzles provided similar cover of the bean leaves, both in the superior and the inferior position of the crop; the application volume of 250 L ha-1 provided higher retention of fungicide in the leaves and higher uniformity of coverage of the plants than the volume of 125 L ha-1; the droplets formed in the application with hollow cone nozzles were more favorable to the drift than the ones produced with flat fan nozzles, specially when low application volume was used; and the applications, in general, provided low deposition uniformity and high drift potential.
