Resumo: During the 1994/1995 growing season at Goiânia, GO, Brazil (altitude 730 m, 16o41'S, 49o17'W), a field experiment was carried out to study spraying nozzles in post-emergent herbicide spray on soybean crop, and their effects on weed control. Droplets were obtained by hydraulic nozzles 110-SF-01 (70 L.ha-1), D2-23 (75 L.ha-1), 110-SF-02 (139 L.ha-1), D3-25 (132 L.ha-1), 110-SF-03 (208 L.ha-1) and D5-25 (200 L.ha-1). Acifluorfen and bentazon were applied with total coverage on soybean and weed plants. Treatments were assessed by measurements of weed control, phytotoxicity, soybean plant height and grain yield. The variation on spraying nozzles did not influence the weed control among studied plants. Although acifluorfen showed better weed control than bentazon, it was more phytotoxic to soybean plants. The different treatments did not show any harmful effects on grain yield or plant height on the soybean crop. KEY-WORDS: Volume of spray; chemical control; sprayer.

O experimento foi conduzido durante o ano agrícola de 1994/1995, no município de Goiânia, GO (altitude de 730 m, latitude de 16o41'S e longitude de 49o17'W), com o objetivo de estudar a eficiência dos bicos de pulverização 110-SF-01 (70 L.ha-1), D2-23 (75 L.ha-1), 110-SF-02 (139 L.ha-1), D3-25 (132 L.ha-1), 110-SF-03 (208 L.ha-1) e D5-25 (200 L.ha-1), na aplicação de herbicidas na cultura da soja. Utilizaram-se os herbicidas acifluorfen e bentazon, aplicados em cobertura total sobre a área. Para avaliação dos tratamentos mediram-se o controle das plantas daninhas, a fitotoxicidade, a altura de plantas de soja e o rendimento de grãos. A simples variação do tipo de bico de pulverização não promoveu alterações significativas nos níveis de controle das plantas daninhas estudadas. O herbicida acifluorfen propiciou níveis de controle mais elevados quando comparados ao bentazon, todavia, foi mais fitotóxico à cultura. Os diferentes tratamentos não ocasionaram efeitos prejudiciais às plantas de soja.
