Resumo: Eichhornia crassipes, known as common water hyacinth, has a high growth rate and produces large amounts of biomass when there are imbalances in water bodies, making it one of the worst aquatic weeds in the world. A study was carried out under small water reservoir field conditions to evaluate the herbicide diquat (960 g ha−1) in controlling this species, at the adult stage development. Four spray tips (AI 11002VS, XR 11002VS and, TXVK-8 with spray volume of 200 L ha−1 and XR 11003VS with 400 L ha−1) were tested. Spraying was performed using a CO2-pressurized sprayer under constant pressure attached to a boat. Plant control was visually evaluated at 1, 3, 7, 11, 14, 21, 29, 60, 87, and 98 days after herbicide application and dry matter accumulation was determined at the end of the experimental period, as well as the spray solution deposition in the application area and water physical and chemical quality. The herbicide diquat was efficient in controlling E. crassipes plants at the dose applied and in development stage of the studied plants, regardless of the type of spray tip at the end of the evaluations. At the beginning of evaluations, the spray tip XR 11002VS was the least effectivity in controlling water hyacinth plants. Spray solution losses were high in all tips tested for control of E. crassipes plants, and the spray tips AI 11002VS and XR 11003VS provided the lowest losses during spraying. No water physical or chemical characteristics were negatively affected by diquat application.

Isto pode afetar os diferentes usos da água, sendo assim considerada uma das piores plantas daninhas aquáticas do mundo. Instalou-se um estudo em condições de pequeno reservatório hídrico para avaliar o herbicida diquat (960 g ha-1) no controle desta espécie. Testou-se quatro pontas de pulverização (AI 11002VS, XR 11002VS, XR 11003VS e TXVK – 8). A pulverização foi realizada com um pulverizador a pressão constante de CO2 acoplado a um barco. As parcelas contendo as plantas de aguapé foram delimitadas por cordas dentro da água. Avaliou-se visualmente o controle das plantas aos 1, 3, 7, 11, 14, 21, 29, 46, 60, 87 e 98 dias após a aplicação do herbicida e acúmulo de massa seca das plantas ao final do estudo, bem como quantificou-se a deposição da calda na área de aplicação e avaliou-se a qualidade física e química da água. O herbicida diquat foi eficiente no controle das plantas de aguapé. Todas as pontas de pulverização testadas no controle de E. crassipes inicialmente foram eficientes, porém a ponta XR 11002VS mostrou-se menos efetiva ao longo do período de avaliação. As perdas de calda de pulverização foram elevadas para todas as pontas testadas no controle das plantas de E. crassipes, sendo que as pontas AI 11002VS e XR 11003VS proporcionaram as menores perdas de produto durante a pulverização. Nenhuma característica física ou química da água foi negativamente afetada pela aplicação do herbicida diquat.EDUFU2022-05-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5360810.14393/BJ-v38n0a2022-53608Bioscience Journal ; Vol. 38 (2022): Continuous Publication; e38027Bioscience Journal ; v. 38 (2022): Continuous Publication; e380271981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/53608/33871Brasil; ContemporaryCopyright (c) 2022 Sidnei Roberto de Marchi, Ricardo Fagundes Marques, Dagoberto Martinshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMarchi, Sidnei Roberto deMarques, Ricardo FagundesMartins, Dagoberto2022-05-24T10:51:14Zoai:ojs.www.seer.ufu.br:article/53608Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-24T10:51:14Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
