Impacto do glyphosate associado a inseticida e fungicida na atividade microbiana e no potencial de solubilização de fosfato em solo cultivado com soja Roundup Ready®

Abstract: RESUMO -Objetivou-se com este trabalho avaliar a atividade microbiana e o potencial de solubilização de fosfato inorgânico em solos cultivados com soja sob diferentes manejos fitossanitários. O experimento foi conduzido em campo, em Argissolo Vermelho-Amarelo câmbico. Foram avaliados dez tratamentos em delineamento de blocos casualizados, no esquema de parcelas subdivididas, com quatro repetições. Nas parcelas, avaliou-se o efeito da aplicação ou não da mistura de inseticida (endossulfan) + fungicida (tebucona… Show more

“…Araújo et al (2003) verified that soils with application of Glyphosate exhibited higher microbial respiration during the beginning of incubation, showing that microorganisms are the main responsible by the biodegradation of the herbicide in the soil. However, Reis et al (2009) did not detected any alteration in respiratory rates in soils treated with Fomesafen + Fuazifop-p-butyl and Glyphosate and with or without application of the mixture of insecticide (Endosulfan) + fungicide (Tebuconaloze). We highlight that scarce studies are available concerning the effect of insecticides on soil microbiology.…”

“…Thus, the study of pesticide's effects on nontarget populations represents an acceptable strategy to evaluate their potential environmental risk (Ferreira et al, 2009). Soil microorganisms promote organic matter breakdown, formation and stabilization of soil aggregates, bio-geo-chemical nutrient cycling within the soil, pathogen suppression, production of phytohormones, breakdown of xenobiotic compounds, among others (Reis et al, 2009;Pôrto et al, 2009).…”

“…The preference for the use of herbicides is due to ease of acquisition and application, less use of manpower and control efficiency. Brazil is the largest consumer of the world's agrochemicals and herbicides are the most marketed (Reis et al, 2009). …”
