Asian soybean rust is one of the main diseases of soybean, which can interfere in the yield and seed quality. The objective of this study was to evaluate physiological quality of soybean seeds produced under different management of Asian rust. Seed production was carried out in a randomized block design with four replicates, in a 5 x 3 factorial scheme, with 5 different fungicides (azoxystrobin + mancozeb + tebuconazole, azoxystrobin + mancozeb, picoxystrobin + ciproconazole + mancozeb, picoxystrobin + ciproconazole and control-without application), and 3 application moments (V8 + R1 + R5, R1 + R5 and R2). The seeds were harvested, dried and stored in a hermetically sealed environment for six months, after which the seeds were analyzed. The variables analyzed were: one thousand seed mass, germination, germination speed index, viability by tetrazolium test, seedling length, dry seedling mass, accelerated aging and electrical conductivity. The results were submitted to analysis of variance and when the F test was significant, the Tukey test (p <0.05) was used to compare means. Soybean seeds treated with the fungicide picoxystrobin + ciproconazole presented better physiological quality. With at least one application of fungicide, all treatments presented greater vigor.
