ResumoThe objective was to evaluate the equipment efficiency in reducing drift and increasing the spray deposition. The experiment was conducted of the conilon coffee plantation, located on the experimental area of the Federal Institute of Espirito Santo, Itapina, Brazil. The experiment was a randomized complete block design with four replications. The treatments consisted: a knapsack sprayer with electrostatic assistance, an electric knapsack sprayer, a knapsack sprayer with a spray shield, and a knapsack sprayer without a spray shield. All sprayers were equipped with a single spray nozzle. Spray deposition was evaluated on wee leaves using a food colourant as a tracer. The knapsack sprayer with electrostatic assistance was the most efficient equipment, providing lower values of drift, and the greatest deposition on the weeds. It is recommended to use the electrostatic sprayer, as it showed greater efficiency in the application of the product on the target, using smaller volume
