Brazil has suffered losses of productivity in virtue of epidemics caused for the Asian rust (Phakopsora pachyrhizi). Had its fast dissemination and high aggressiveness, the treatment of seeds can be responsible for the success in its control. This work had as objective to evaluate the control of the Asian rust using the Fluquinconazole fungicide in the treatment of seeds, associate or not to pulverizations accomplished foliate fungicides in the culture of the soy (Glycine max L. Merrill). The experiment was lead in the Farm Capim Branco-Uberlandia and the statistical design was casual between blocks, with 4 repetitions and 6 treatments, using cultivating M-soy 8000 RR. The analyzed variable had been: emergency, number of lesion per cm(2), severity, takes away the leaves, productivity, weight of a thousand grains and AACPD. The treatments had been: Piraclostrobina + Epoxiconazole, Prothioconazole, Fluquinconazole, Tebuconazole + Trifloxystrobina, combined with treatment of seeds and foliate applications. All the treatments had presented some control on the illness, where with Fluquinconazole in treatment of seeds combined with three intermediate applications of Prothioconazole and Trifloxystrobina + Tebuconazole in foliate applications bigger income and weight of a thousand grains had reduced the progress of the illness providing.
