The objective of the present study was to evaluate the efficiency of aqueous extracts and essential oils on seed quality of sorghum cultivar BR 310. Two experiments were conducted, one using sorghum seeds treated with aqueous extract of Cinnamomum zeylanicum and Mentha spicata and another using essential oils of Ocimum gratissimum and Annona crassiflora. For the experiment with extracts concentrations were 0, 10, 20 and 30% and for the oils were 0, 5, 10 and 15 ?L/mL. We evaluated the following characteristics: seed health (Blotter test), germination, first count of germination and germination speed index. The design was a DIC in 2 x 4 factorial arrangement, two oils or two extracts with four concentrations, independent testing. Several fungal species were associated with the seed, and the genus Curvularia the most prevalent. The aqueous extract of cinnamon (Cinnamomum zeylanicum) and clove essential oil of basil (Ocimum gratissimum) have shown promise for the treatment of seeds, reducing fungal infestation, especially Curvularia, however have phytotoxic effect reducing the viability and vigor of sorghum seeds.
