Efeito de herbicidas na atividade microbiana do solo cultivado com diferentes genótipos de cana-de-açúcar

Abstract: Resumo -Objetivou-se com o trabalho avaliar o efeito de herbicidas sobre a atividade microbiana do solo cultivado com cana-de-açúcar. O delineamento experimental utilizado foi de blocos casualizados, com quatro repetições. Os tratamentos foram arranjados em esquema fatorial 5 x 4. No Fator A alocou-se os genótipos de cana-de-açúcar: RB72454, RB835486, RB855113, RB867515 e RB947520 e no B os herbicidas: ametryn (2000 g ha -1 ), trifloxysulfuron-sodium (22,5 g ha -1 ), ametryn + trifloxysulfuron-sodium (1463 + 3… Show more

“…As examples of inputs usually carried out in conventional production systems with influence in soil microbial activity, Vivian et al [48] evaluated the influence of the sulfametrazone herbicide on the microbial activity in an Oxisol and verified toxic action of the herbicide in the soil microbial community. In a similar way, when evaluating the influence of the residual effect of the herbicide sulfametrazone on the microbiological activity, Galon et al [49] observed a decrease in the metabolic quotient of the soil as a function of time, concluding that the toxic effect of the herbicide is able to alter the long-term soil microbiota. Tironi et al [50] reported a decrease in soil respiratory rate as a function of the application of an herbicide of the chemical group Sulfonylurea compared to a treatment without herbicide application.…”

“…Desta forma, a mensuração do carbono(C) da biomassa microbiana é um importante indicador de mudanças na química do solo e possibilita o monitoramento da relação entre química do solo e vegetação de cobertura. Assim o carbono da biomassa microbiana pode atuar como um indicador ambiental (Galon et al, 2014).…”

“…Thus, indiscriminate or careless use of these technological tools (no-tillage with herbicideresistant GMOs) has caused a number of problems. Among these, a higher probability of weed-resistant biotypes selection, as well as negative impacts on non-target organisms (Christoffoleti et al, 2008;Menezes et al, 2012a,b;Galon et al, 2014).…”
