Efeitos do glyphosate e sulfometuron-methyl no crescimento e na qualidade tecnológica da cana-de-açúcar

Abstract: Os herbicidas, mesmo quando usados em doses reduzidas ou utilizados como maturadores, podem alterar a morfofisiologia da planta, o que pode levar a modificações qualitativas e quantitativas na produção. O presente estudo objetivou avaliar a eficiência agronômica e os efeitos, durante o crescimento da cana-soca, da aplicação de glyphosate e sulfometuron-methyl em baixas doses. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. Os tratamentos foram constituídos pelos herbi… Show more

“…Evaluating the effect of glyphosate in the post-harvest plant development, Meschede et al (2010) observed interruption of growth in height in the initial plant development, at 30 DAH, but at the end of the cycle, there was no effect of treatments.…”

“…On the other hand, there are reports that the use of glyphosate and sulfometuron methyl did not cause negative or significant effects on sugarcane yield components and production (Banasihan et al 2007;Meschede et al 2010). Viator et al (2011) found that glyphosate application decreased stalk and sucrose yields when post-harvest residue was not removed on the second ratoon crop compared with the control, but when the residue was removed by burning, glyphosate application did not significantly affect cane or sucrose yields.…”

“…ALS is the first enzyme of the branched chain amino acids synthesis route, valine, leucine and isoleucine (Zhou et al, 2007;Warwick et al, 2010). Herbicides derived from sulfonylurea, even when used in reduced doses or as ripeners, present high activity level and may have important implications, such as the alteration of metabolite processes balance and plant morphophysiology, which may interfere negatively on production (Meschede et al, 2010(Meschede et al, , 2011. They are active both via leaf and soil, and, after absorption, they are quickly transferred to active growth areas, meristems, apexes, where growth is inhibited in sensitive plants (Oliveira Júnior, 2011).…”
