Resumo
Soybean 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.
