This trial was carried out to evaluate the effect of the surfactant Aterbane on spray solution deposition applied over Pistia stratiots plants. The treatments were concentrations of Aterbane at 0, 0.25 and 0.5% used in a spray solution preparation with brilliant blue FDC-1 at 1,500 ppm as tracer. The experimental treatments were set up in a randomized design with 30 replications. Application was performed with stationary spray equipment with pressure at 2 bars and consumption of 200 L ha-1. XR 11002vs nozzles were used. Aterbane did not improve the quantity of spray solution deposition but it improved quality deposition, the higher the concentration, the greater the uniformity of the spray solution deposition.
