Resumo: the aims of this study were to determine imazapyr efficacy for floating macrophyte control and ecotoxicology for non-target organisms. For the floating macrophyte control efficacy tests were used the doses of 0,5; 1,0; 2,0; 2,5; 3,0; 3,5 and 4,0 L ha(-1) and a control with 10 replicates. The acute toxicology for non-target organisms was estimated by lethal concentration 50% (LC50 and EC50). The floating macrophyte control efficacy was over 90%. Imazapyr was classified as moderately toxic for the following biomarkers: L. minor, H. eques, B. rerio, P. caudimaculatus, P. canaliculata, and P. mesopotamicus and lightly toxic for A. caroliniana. Thus, imazapyr herbicide is a tool with great potential to be used on floating macrophyte control (E. crassipes, P. stratiotes e S. molesta) in Brazil and this practice can be evaluated by the use of application biomarkers.

Para os ensaios de eficácia de controle das macrófitas flutuantes, foram utilizadas as doses de 0,5; 1,0; 2,0; 2,5; 3,0; 3,5 e 4,0 L ha-1 e um controle com 10 réplicas. A toxicidade aguda para organismos não alvos foi estimada pela concentração letal de 50% (CL50 e CE50). A eficácia de controle para as macrófitas flutuantes foi acima de 90%. O imazapyr foi classificado como moderadamente tóxico para os bioindicadores L. minor, H. eques, B. rerio, P. caudimaculatus, P. canaliculata e P.mesopotamicus e ligeiramente tóxico para A. caroliniana. Assim, o herbicida imazapyr é uma ferramenta com grande potencial para ser usada no controle de macrófitas flutuantes (E. crassipes, P. stratiotes e S. molesta) no Brasil, e a sua utilização pode ser avaliada por meio de bioindicadores de aplicação.Ctr Univ Fundacao Educ Barretos, Barretos, SP, BrazilUNESP, Nucl Estudos &Pesquisas Ambientais Matol, Jaboticabal, SP, BrazilUniversidade Estadual Paulista, Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal, Nucl Estudos &Pesquisas Ambientais Matol, Jaboticabal, SP, BrazilUniv Federal VicosaCentro Universitário da Fundação Educacional de Barretos (UNIFEB)Universidade Estadual Paulista (Unesp)Cruz, Claudinei da [UNESP]Silva, A.
