Abstract: Após sucessivos anos, aplicações do herbicida glyphosate em pomares de citros no Estado de São Paulo selecionaram biótipos resistentes de Conyza bonariensis e C. canadensis. Na ocorrência de plantas daninhas resistentes em uma área agrícola, tornam-se necessárias mudanças nas práticas de manejo para obtenção de adequado controle das populações resistentes, bem como para a redução da pressão de seleção sobre outras espécies. Assim, este trabalho foi realizado com o objetivo de identificar herbicidas alternativo… Show more

“…When comparing equivalent treatments with or without the addition of 2,4-D, the control increase becomes evident; without 2,4-D, it varied from 55 to 65% and from 75 to 90% when there was 2,4-D addition (Table 2). These results support the low control levels obtained on day 14 DAA in the association of glyphosate with chlorimuron-ethyl and flumioxazin (Moreira et al, 2010). The increase in controlling resistant hairy fleabane with the association of 2,4-D is due to the synergism with glyphosate, which helps the absorption and translocation (Waggoner et al, 2011;Takano et al, 2013), contrasting the possible antagonistic effects of the mixture glyphosate with chlorimuron-ethyl and flumioxazin over morning glory, where there was control reduction up to 30% Arnold, 2002).…”

“…The reality of the Brazilian agriculture shows it is not, otherwise the disturbance caused by herbicides would be enough to eliminate Conyza -but they became resistant. This is Nature always one Fortunately, most technical bibliography, as that by Constantin et al (2013) and several others (Vargas et al, 2007;Lamego & Vidal, 2008;Moreira et al, 2010;Silva et al, 2014;Pereira, 2015), do not face the problem of Conyza with simplicity and levity. It is a fact that the problem of Conyza in Brazil started in the 1980's, as evidenced in Table 1, when the no-till planting system was gaining importance; there is no evidence, however, which links the spread of no-till to the occurrence of Conyza.…”
