Characterizing the environmental fate of DvSnf7 double-stranded RNA (dsRNA) produced by MON 87411 maize (Zea mays L.) in Brazilian soils is a critical component to a comprehensive environmental risk assessment. This study shows that DvSnf7 dsRNA dissipated rapidly in tropical soils, with results comparable to those previously reported in soils from North America. These results suggest that dsRNA produced by maize MON 87411 is unlikely to persist in soil following cultivation in tropical environments.
