Foi investigada a ação de fungicidas registrados na cultura de videira, sobre a atividade de leveduras assim como a dose de inibição equivalente do fungicida que apresentasse maior efeito. Uvas da cultivar Cabernet Sauvignon foram tratadas, nas doses recomendadas, com 13 fungicidas. Uvas não tratadas e tratadas com fungicida foram colhidas, respeitando os prazos de carência, e submetidas à microvinificação. O experimento foi conduzido num delineamento inteiramente casualizado com três repetições. A ação dos fungicidas foi avaliada em leveduras autóctones e sobre a linhagem selecionada Saccharomyces cerevisiae Embrapa 1vvt/97. Captan, folpet, mancozeb, tebuconazole, azoxystrobin e famoxadone+mancozeb foram os que mais ação inibidora apresentaram sobre as autóctones. Sobre a selecionada, os mais inibidores foram captan, folpet, tetraconazole. Tiofanato metil e famoxadone+mancozeb mostraram-se estimulantes para as leveduras autóctones e selecionada, respectivamente. A levedura selecionada apresentou uma redução exponencial da atividade metabólica da ordem de 0,013 g CO2/mg captan/L. |

The production and emission of CO2 in native, pasture and cultivated areas is a result of microbiological activity and mineralization of organic matter, and depends on favorable environmental factors, such as temperature, availability of water and of land use. The results of this work show that the no tillage system (NT) has the potential to mitigate 37.7% of C-CO2 efflux from cultivation of soy compared to conventional tillage (CT). The temperature of the soil accounted for 65% of the variability of the flux of CO2-C in CT. The variation of soil moisture explained 73 and 51% of the flux of CO2-C in CT and NT, respectively. These results indicate that soil moisture and soil temperature were controlling factors of CO2-C emissions from soil to atmosphere because these parameters directly affect soil microbial activity. The results also show that the active pasture had the highest outflows of soil CO2-C to the atmosphere in relation to forests and degraded pasture in Western Pará. Furthermore, it was shown that both the pastures and forests have seasonality in the fluw, which mainly related to precipitation patterns and water potential between soil and air. We observed a strong correlation between the efflux and soil moisture of both capoeira and in the pastures, as the soil temperature was a controlling factor of the active efflux only in the pasture. The average fluw of CO2-C obtained in pasture active was 218.9 mg C m-2 h-1 value of 40.7% higher than the primary forests and 155.5 mg C m-2 h-1. Finally, the results presented here suggest that the conventional tillage and pasture management are activities strongly associated to human enhance biogeochemical changes in the balance of carbon in these ecosystems, since the efflux of CO2-C is related to soil primary productivity of these ecosystems.
