Tempo de contato e de combinações de fungicidas, aditivo e inoculante sobre a sobrevivência de rizóbios e nodulação da soja.

Abstract: Resumo -Objetivou-se com este trabalho avaliar o efeito do tempo de contato e de combinações de fungicidas, aditivo e inoculante, no tratamento da semente, na sobrevivência de bactérias fixadoras de nitrogênio atmosférico e nodulação da soja. Realizouse ensaios em laboratório para verificar a sobrevivência de bradirrizóbios, e em casa de vegetação para avaliar a formação de nódulos na raiz de plantas de soja. Em laboratório o delineamento foi inteiramente casualizado, com três repetições, com os tratamentos ar… Show more

“…When the seed was inoculated with A. brasilense and without the use of the fungicide, an increase of 1.8 cm was observed for RL. Some fungicides may lead to deleterious effects four hours after contact with bacteria (ALCÂNTARA NETO et al, 2014) or cause the death of up to 100% of bacteria (CAMPO et al, 2009); however, the viability of the bacteria has not been evaluated in this study. It is assumed that, in addition to the active ingredient, the pH (SIQUEIRA, FRANCO, 1988) is responsible for the reduction in the number of viable cells (BASHAN et al, 2004) or bacterial death (ARAÚJO; ARAÚJO, 2006) caused by direct contact with fungicides.…”

“…Fungicides and insecticides may adversely affect the proliferation of soil microorganisms, impairing their survival or causing the death of the seedinoculated bacterial cells (ALCÂNTARA NETO et al, 2014;CAMPO et al, 2009) due to the potential toxic effects of their active ingredients. Some pesticides disrupt the interactions between plants and N-fixing bacteria and consequently inhibit the vital process of biological nitrogen fixation (BNF) (ARAÚJO; ARAÚJO, 2006).…”

“…No Brasil, o melhor exemplo de aplicação da FBN é a inoculação de soja (Glycine max. (L.) Merrill) com estirpes do gênero Bradyrhizobium, tornando a adubação nitrogenada desnecessária e garantindo maior competitividade desta commodity no mercado internacional (NETO et al, 2014).…”
