Tensão superficial estática de misturas em tanque de glyphosate + chlorimuron-ethyl isoladas ou associadas com adjuvantes

Abstract: RESUMO -Objetivou-se neste estudo avaliar a tensão superficial estática, o pH e a produção da espuma de misturas em tanque de glyphosate + chlorimuron-ethyl, associadas ou não com adjuvantes. Dois trabalhos foram realizados, sendo a primeira etapa desenvolvida em delineamento inteiramente casualizado com seis tratamentos e 20 repetições, representados por soluções dos herbicidas glyphosate (540,0 g e.a. ha ) e chlorimuron-ethyl (7,5 g ha ABSTRACT -This work aimed to evaluate static superficial tension, pH and … Show more

“…The solution with glyphosate has a diminution the reduction in surface tension when vegetable oil and mixture tributyl citrate + polydimethylsiloxane were added, except at 180 seconds (Figure 1 With a greater spreading factor, can occur a reduction of the maximum quantity of liquid retained by the leaves, as showed in the research of ANDRADE et al (2010), where was observed that the addition of oil, either mineral or vegetable, to an acaricide in the spraying solution reduced the maximum quantity of liquid retained by the leaves of citrus plants, which suggested the possibility of reducing the amount of solution needed for good coverage of the plant. MACIEL et al (2010) also reported that mineral oil proved effective in reducing the surface tension for tank mixing with glyphosate formulations and with chlorimuron-ethyl.…”

“…The spraying was carried out on 11/11/2010, using a CO2 pressured costal sprayer maintained at work pressure of 2.1 kgf cm -2 , equipped with two nozzles (TeeJet The physico-chemical characteristics related to pH, static surface tension and conductivity of the herbicide solutions, with and without adjuvant, were also evaluated using the methodology described by Maciel et al (2010).…”

“…As características físico-químicas, referentes ao pH e tensão superficial estática das soluções foram avaliadas, conforme metodologia descrita por Maciel et al (2010), assim como para o controle das plantas daninhas aos 3 e 9 dias após aplicação (DAA), considerou-se uma escala percentual de notas, sendo 0% ausência de controle e 100% a morte das plantas (SBCPD, 1995).…”
