Resumo: The experiment was carried out in the cerrado region of Goiânia, Goiás State, Brazil. The objective was to study the uniformity of drop deposition from spraying of the hydraulic Boomjet 5880-3/4-2TOC2095 nozzle in operation bands of 10 m, 12 m, and 14 m, and applied at 1.0 m, 1.3 m, and 1.5 m above plant tops. For treatment evaluation the variables drop density (droplets.cm-2) and control of Urochloa decumbens (Stapf) R. Webster plants were measured. The mathematical simulation of the overlapping bands application in both directions, unidirectional and bidirectional, showed low sprayed drop deposition uniformity, statistically represented by variation coefficients ranging from 61.46 % to 98.91%. Low values for drop density were obtained at specific points of the application band. Glyphosate applications at the three-studied nozzle application heights showed satisfactory control with operations bands of 10 m and 12 m. KEY-WORDS: Weeds; agrochemical; no-tillage; pasture.

O experimento foi conduzido na região do cerrado no município de Goiânia, GO. Objetivou-se estudar a uniformidade de deposição das gotas de pulverização produzidas pelo bico hidráulico Boomjet 5880-3/4-2TOC20, com faixas operacionais de 10 m, 12 m e 14 m e aplicações realizadas a 1,0 m, 1,3 m e 1,5 m de altura em relação ao topo das plantas a serem dessecadas. Para avaliação dos tratamentos mediram-se as variáveis densidade de gotas (gotas.cm-2) e controle de plantas de Urochloa decumbens (Stapf) R. Webster. A simulação matemática da sobreposição das faixas de aplicação nos dois sentidos, unidirecional e bidirecional, mostraram elevada desuniformidade de deposição das gotas pulverizadas, estatisticamente representada por coeficientes de variação que variaram de 61,46% a 98,91%. Valores reduzidos referentes à densidade de gotas foram obtidos em pontos específicos da faixa de aplicação. Em pulverizações de glyphosate, o estudo mostrou controle satisfatório ao se adotar larguras de faixas de 10 m e 12 m, com o bico posicionado nas três alturas de aplicação estudadas.
