Abstract: RESUMO -O objetivo deste trabalho foi avaliar a lixiviação de saflufenacil em Latossolo Vermelho-Amarelo (textura média, pH 5,6) e Latossolo Vermelho distrófico (textura argilosa, pH 5,2 e pH 6,0), assim como os efeitos de períodos de seca no residual desse herbicida. A lixiviação de saflufenacil (0,10 g i.a ha -1 ) e, adicionalmente, a lixiviação de diuron + hexazinone (1.170 + 330 g i.a. ha -1 ) foram avaliadas sob simulação de chuva (40 mm). O herbicida saflufenacil aplicado em solo argiloso com pH 6,0 apre… Show more

“…The soil persistence of approximately 90 days noted by Monquero et al (2012) was much higher than that observed in our study, which can be explained by the lack of soil moisture after the application of saflufenacil, as reported by the authors, which acted to inhibit herbicide dissipation. Moreover, a study carried out in the United States on a soil classified as a Sequatchie loam found that saflufenacil had a halflife of 21.4 days (Mueller et al, 2014).…”

“…Long periods of drought reduce the persistence of this herbicide as 28 days of drought maintained herbicidal activity at 80% effectiveness, and 90 days of drought reduced herbicidal activity to 8% effectiveness (Monquero et al, 2012).…”

“…Monquero et al (2012) showed that the saflufenacil presented high leaching in two Latosols (Oxisols) with different textures, which was more pronounced in the sandy texture. Saflufenacil is a moderated acid, which has pKa of 4.3.…”

“…However, the strong dependence on glyphosate in croplands has resulted in loss of its effectiveness in weeds, that became tolerant to this herbicide due to selection pressure (MOREIRA et al, 2007;OWEN, 2008;POWLES, 2008;YAMAUTI et al, 2010). Thus, the combination of herbicides with different mechanisms of action may be a viable alternative to ensure the success in weed managements.…”
