The objective of this study was to evaluate the economic viability and quantify the risks of events related to the potential adoption of a new transgenic bean cultivar (BRSF401 RMD), resulting from the previous identification of the BGMV (Bean Golden Mosaic Virus) and subsequent occurrence of the Carla Virus Cowpea mild mottle virus (CpMMV) whose vector, the whitefly (Bemisia tabaci), causes serious crop damage. A partial budget and simulation of the cumulative probability distribution for whitefly control decision were developed to measure the effects of different dosages of insecticides on transgenic beans, at different planting times, and the probability of economic risks in different crops ( rainy, droughts and winter seasons), production protocols and producers' perceptions regarding the potential adoption of transgenic technology. The agroeconomic viability analysis of the cultivar was based on 11 field trials in localities of Goiás, Minas Gerais and the Federal District. Semi-structured questionnaire was used in interviews with 37 farmers and bean technical consultants from the municipality of Cristalina - GO. The results indicated that the treatments with the transgenic cultivar were more pronounced in relation to the conventional ones in the crops of the waters and droughts, and in the winter the conventional and the transgenic did not show significant differences. The producers of Cristalina-GO believe that this new technology, transgenic beans, may promote improvements in disease control, however they lack agronomic information of the cultivar, possible occurrences in the market and acceptance by consumers.
