ResumoSoybean is an important crop in the economical agriculture of Brazil and it has productive potential compromised by a variety of diseases affecting the crop such as soybean rust ( Phakopsora pachyrhizi ). The aim of this study was to evaluate the efficiency of incorporating fluquinconazole into the soybean seed treatment in the management of the disease, associated with spray of different fungicides on leaves. The work consisted of two trials side by side on the field. The first trial consisted of several fungicides used to control soybean rust (azoxistrobin, cyproconazole, trifloxystrobin, tebuconazole and prothioconazole) and seed treatment with carbendazim + thiram, and fluquinconazole. The second trail was identical to the first, but without the use of fluquinconazole. The experiment was carried out into two localities – Goiânia (GO) and Senador Canedo (GO). In both experiments, fungicides applied on leaves were effective controlling soybean rust, however the incorporation of fluquinconazole on the soybean seed treatment did not increase the control of the disease since neither it delayed the onset of the disease nor significantly increased the productivity of the crop.
