• Soybean is subject to occurrences of pathogens transmitted by seeds, requiring phytosanitary treatment, however, it can be toxic to humans and the environment. The objective of this study was to evaluate the effect of essential oils of rosemary (Rosmarinus officinalis) and eucalyptus (Corymbia citriodora) on the control of phytopathogenic fungi in stored soybean seeds. The experiment was carried out in a completely randomized design, using a 2 * 5 factorial arrangement consisted of seeds with and without fungal inoculation (Aspergillus favus and Penicillium rubens) and five seed treatments (three essential oils, positive control, and negative control), with four replicates. Rosemary and eucalyptus essential oils and their combination were applied to soybean seeds at the rate of 4 mL k[g.sup.-1], at a concentration of 700 [micro]L m[L.sup.-1]. Distilled water with 2% Tween[R] 80 was used as negative control, and the commercial fungicide Vitavax-Tiram[R] 200SC was used as positive control, according to the manufacturers' recommendations. The R. officinalis essential oil was efficient in the control of Penicillium sp. in stored soybean seeds and showed a similar effect to the positive control. The C. citriodora essential oil reduced the incidence of Aspergillus sp. Therefore, these essential oils have potential to be used as an alternative control of soybean seed pathogens.

Objetivou-se avaliar o efeito dos oleos essenciais de alecrim (Rosmarinus officinalis) e eucalipto (Corymbia citriodora) no tratamento contra fungos fitopatogenicos em sementes de soja armazenadas. O experimento foi em delineamento inteiramente casualizado em arranjo fatorial 2 * 5, para sementes com e sem inoculacao de fungos (Aspergillus favus e Penicillium rubens) e cinco tratamentos de sementes (tres oleos essenciais, controle positivo e controle negativo), com quatro repeticoes. Os oleos essenciais de alecrim, eucalipto e a combinacao destes foram aplicados na dose de 4 mL k[g.sup.-1] de sementes de soja, na concentracao de 700 [micro]L m[L.sup.-1]. Como controle negativo (testemunha) utilizou-se agua destilada com Tween[R] 80 a 2% e como controle positivo o fungicida comercial Vitavax-Tiram[R] 200SC, conforme dosagem do fabricante. O oleo essencial de R. officinalis foi efficiente no controle de Penicillium sp. nas sementes de soja armazenadas e apresentou efeito semelhante ao controle positivo. O oleo essencial de C. citriodora reduziu a incidencia de Aspergillus sp. Portanto, estes oleos essenciais tem potencial para serem utilizados no controle alternativo de patogenos de sementes de soja. Palavras-chave: Glycine max (L.)
