The objective of this study was to evaluate the effect of polymer coating and fungicide on seed quality of soybean cv. AG 7000 seed lots with high and low germination rates. The seed film coating was performed using two commercial brands of polymers, LABORSAN®, and LANXESS®, in doses of 2.0 and 3.5 ml for each kg, with and without mixture of the fungicide Carbendazim Thiram (firewalk®). The seed quality evaluation was measured by the germination test, germination in sand, and accelerated aging. The use of polymers in soybean seeds provides seeds with good appearance and coloration and it can be applied to differentiate the seed from the commercial grain. The fungicide and the polymers do not affect the physiological quality of soybean seeds. The results of the polymer and fungicide are higher in the accelerated aging test, with the highest percentage of germination of soybean seeds in relation to the control.
