This study aimed to evaluate the effects of bean desiccation (Talismã cultivar) with carfentrazone-ethyl on seed quality. Desiccation was performed by applying 5 rates (0, 10, 30, 60 and 120 g ha-1) of carfentrazone-ethyl associated to three application times, 25, 30 and 35 days after flowering (DAF). Humidity loss was quantified two days after each application. Harvest was performed eight days after each application, followed by determination of the weight of 100 seeds, and the proportion of seeds was classified as "small" (passed through sieve 14/64"), "medium" (retained in sieves 14/64" and 16/64") and "larger" (retained in sieves 16/64") and the germination test (GT). Carfentrazone-ethyl application, at doses superior to 60 g ha-1 rates, 25 DAF, accelerated seed humidity loss, affecting the size and weight of 100 seeds. Desiccant application between 10 and 30 g ha-1 rates, 30 DAF, provided better results, larger yield and seed quality without a negative effect on germination.
