Abstract: The sanitary and physiological qualities of soybean seeds are determining factors for the establishment of appropriate stands. This research aimed to evaluate the soybean seed performance and plants growth after seed inoculation with Colletotrichum truncatum and fungicide treatment by film-coating. The seeds were inoculated whit C. truncatum by water restriction technique and then treated with fungicides and polymer. The used treatments were carbendazin, fludioxonil+mefenoxan, thiabendazole+thiram, thiophanate methyl, caboxin+thiram and untreated seeds. The seeds were treated with and whitout polymer. Seed germination, cold test, seedling emergence and seed health test (blotter test) were evaluated. Plants grown in pots were evaluated using length of aerial parts, dry matter of roots and aerial parts. The best control of C. truncatum was obtained when the seeds were treated with fludioxonil+mefenoxan and thiabendazole+thiram. These treatments also contributed to improve the physiological performance of the seeds. The soybean seeds vigour and the plants growth were reduced when the seeds are treated whit methyl thiophanate. The film-coating do not affect the physiological potential and the soybean seed health.
