Manejo químico de convolvulaceae e euphorbiaceae em cana-de-açúcar em período de estiagem

Abstract: RESUMO -As famílias Convolvulaceae e Euphorbiaceae possuem diferentes espécies que infestam os canaviais de forma rápida e agressiva, especialmente em áreas cobertas pela palha remanescente da colheita que não foram queimadas. Essa infestação, associada às extensas áreas de cultivo, tem dificultado a operacionalidade do manejo químico exclusivamente durante a estação chuvosa do ano, levando aos produtores a necessidade de aplicar os herbicidas também no período de estiagem. Nesse contexto, o presente trabalho … Show more

“…Azania et al (2009) According Guzzo et al (2010), plants of I. hederifolia present its higher extraction of macronutrients at 63 DAE, period next to PPI occurrence obtained in this study (76 DAE). Pitelli (1987) classifies as "direct interference" the competition for nutrients and states that this is one of the most important forms of interference between weed and crops.…”

“…One of the main changes occurred in the management of weeds (Ferreira et al, 2010;Azania et al, 2011). The permanence of a dense straw on soil significantly changed the composition of sugarcane weed community (Azania et al, 2008(Azania et al, , 2009(Azania et al, , 2011. The straw layer kept in this system acts as a physical barrier for seedling emergence and for positioning of pre-emergent herbicides, changing water balance, temperature range of soil surface, quantity and quality of light (Ferreira et al, 2010;Velini & Negrisoli, 2000).…”

“…Other studies have also assessed the efficacy of sulfentrazone in controlling Ipomoea species in sugarcane crop production (Viator et al 2002;Jones and Griffin, 2008;Azania et al, 2009). The susceptibility of species in this genus to sulfentrazone has been attributed to a low metabolism rate of the herbicide by the plants along with inefficient antioxidant systems (Thomas et al, 2005).…”

“…As cordas-de-viola são problemas na cultura da cana-de-açúcar devido à competição por água, luz e nutrientes, entretanto, os prejuízos estão mais relacionados às operações de manejo da cana-de-açúcar, em especial na operação de colheita (Azania et al, 2009), intensificada à medida em que houve o incremento da mecanização na cultura (Almeida et al, 2017).…”
