This study was carried out at Escola de Agronomia - Universidade Federal de Goiás, Goiânia - GO, in order to evaluate the efficiency of the following fungicides to soybean seeds treatment: 1) thiabendazole + thiram (17 + 70 g.a.i./100kg); 2) benomyl + thiram (g.a.i./100kg); 3) difenoconazole (5,0 g.a.i./100kg); 4) difenoconazole + thiram (5,0 + 70 g.a.i./100kg); 5) difenoconazole + captan (5,0 + 90 g.a.i./100kg); 6) carbendazin + thiram (30 + 70 g.a.i./100kg); 7) control. All fungicides reduced Fusarium semitectum and Colletotríchum truncatum incidence. Benomyl + thiram presented the highest efficiency in the control of these patogens. Difenoconazole didn’t present reasonable results, but difenoconazole + thiram was similar to thiabenazole + thiram. In field conditions, there was a meaningful increase in plant population as well as in productivity due to the fungicides treatment. Difenoconazole + thiram and carbendazin + thiram treatments provided higher stand at 12, 18 and 26 days after planting. KEY-WORDS: Fusarium semitectum; Colletotrichun truncatum; chemical control.
