Summary: The goals of this study were to evaluate the application of glyphosate plus three adjuvants and three spray nozzles in controlling the macrophyte Pistia stratiotes. For this purpose, after an 80 to 90% colonization, the application of 1.5, 3.5 and 7.0 L h-1 of isolated glyphosate and with the adjuvants Aterbane® BR, Veget’oil® and Dash® HC (0.5% vv-1) and the spray nozzles (AI 110.02, TTI 110.015 and TT 110.015) was performed, plus a control sample (water). Applications were performed with a pressurized backpack precision sprayer, at the constant pressure of 50 p.s.i. and with mixture consumption of 200 L ha-1. At the dose of 1.5 L ha-1, there was 100% control for the combination glyphosate + Veget’oil + tip AI 110.02 (Gly+V.oil+AI, Gly+Aterb.+TTI and Gly+Dash+TT) 15 days after application (DAA). At 3.5 L ha-1, the greatest control (95%) was with Gly+AI, Gly+Aterb.+TTI, Gly+V.oil+TTI, Gly+Dash+TTI, Gly+Aterb.+TT and Gly+Dash+TT; and at 7.0 L ha-1 100% was observed for Gly+AI, Gly+Aterb.+AI, Gly+V.oil+AI, Gly+Aterb.+TTI, Gly+V.oil+TTI, Gly+Dash+TTI, Gly+TT and Gly+Dash+TT. Thus, it is possible to conclude that at 1.5 L ha-1, the combination of glyphosate plus Dash® and with the nozzle TT 110.015 (Gly+Dash+TT) was the most promising one; at 3.5 L ha-1, it was Gly+Aterb.+TTI and at 7.0 L ha-1 the air induction nozzles (AI 110.02 and TTI 110.015), whether with isolated glyphosate or with any of the three adjuvants, were the best at providing control.

Para isso, após a colonização de 80 a 90%, foi realizada a aplicação de 1,5, 3,5 e 7,0 L ha-1 de glyphosate isolado e com os adjuvantes Aterbane® BR, Veget’oil® e Dash® HC (0,5% vv-1) e pontas de pulverização (AI 110.02, TTI 110.015 e TT 110.015) e um controle (água). As aplicações foram feitas com pulverizador costal pressurizado de precisão, à pressão constante de 50 p.s.i. e consumo de calda de 200 L ha-1. Na dose de 1,5 L ha-1 houve 100% de controle para a combinação glyphosate + Veget’oil + a ponta AI 110.02 (Gly+V.oil+AI), Gly+Aterb.+TTI e Gly+Dash+TT em 15 dias após aplicação (DAA). Em 3,5 L ha-1 o maior controle (95%) foi para Gly+AI, Gly+Aterb.+TTI, Gly+V.oil+TTI, Gly+Dash+TTI, Gly+Aterb.+TT e Gly+Dash+TT, e em 7,0 L ha-1 chegou-se a 100% para Gly+AI, Gly+Aterb.+AI, Gly+V.oil+AI, Gly+Aterb.+TTI, Gly+V.oil+TTI, Gly+Dash+TTI, Gly+TT e Gly+Dash+TT. Assim, conclui-se que em 1,5 L ha-1 a combinação de glyphosate com o Dash® e a ponta TT 110.015 (Gly+Dash+TT) foi a mais promissora; em 3,5 L ha-1 foi Gly+Aterb.+TTI e em 7,0 L ha-1 as pontas com indução de ar (AI 110.02 e TTI 110.015), independentemente de o glyphosate estar isolado ou com qualquer um dos três adjuvantes, foram as melhores no estabelecimento do controle.Universidade Estadual Paulista, UnespCentro Universitário da Fundação Educacional de BarretosUniversidade Estadual Paulista, UnespSociedade Brasileira da Ciência das Plantas DaninhasUniversidade Estadual Paulista (Unesp)Centro Universitário da Fundação Educacional de BarretosSilva, A.f.
