Sesame (Sesamum indicum L.) is as an important oilseed crop and seed borne fungi are reducing the yield as well as quality of the seeds produced. The present study aimed to evaluate the effect of essential oils for control of seed borne fungi as well as enhancement of seed quality of sesame. Fusarium sp., was isolated from sesame seeds by agar plate method. Four essential oils such as camphor oil, cinnamon oil, clove oil and rose oil were screened for their antifungal potential against the isolated Fusarium sp., by poisoned food method. Selected essential oils were tested at different concentrations of 100, 200, 300, 400 and 500 ppm concentrations for their ability to inhibit the mycelial growth of test fungi. All the oils completely inhibited the mycelial growth of test fungi at 500 ppm concentration. The effect of selected essential oils on sesame seed quality was analyzed by standard blotter method. All the four oils increased the germination percentage and seed vigour while the fungal infection was completely inhibited without any phytotoxic effects. Comparatively, clove oil showed the best activity followed by camphor oil, cinnamon oil and rose oil. These results observed of the essential oils indicate the possible usage of them for the sesame seed treatment following further investigations.

Dimorphandra gardneriana, popularly known as fava d’anta, is a medicinal species whose fruits and seeds are used in the manufacture of medicines. The objective of this study was to evaluate the efficiency of clove (Syzygium aromaticum (L.) Merr. & L.M. Perry) and copaíba (Copaifera sp.) essential oils in antifungal treatment of seeds of D. gardneriana and their influence on physiological quality of the seeds. Two experiments were carried out in a completely randomized design using seeds treated with different concentrations of copaiba and clove oils (0.5, 1.0, 1.5, and 2.0 mL) and two controls—seeds were treated with distilled water or fungicide. The variables analyzed were: incidence of fungi in seeds in the first experiment and seed germination and vigor (first germination, length and dry mass of root and shoot of the seedlings) in the second one. The incidence of fungi of the genera Aspergillus sp., Penicillium sp., and Rhizopus sp. in the seeds was elevated. The copaiba oil at the concentrations used did not satisfactorily reduce the incidence of fungi in the seeds of D. gardneriana, while the treatment of the seeds with clove oil at concentrations of 2.0 and 0.5 mL reduced the incidence of Penicillium sp. and Rhizopus sp., respectively. Seed germination and vigor increased at concentrations of 2 mL of clove oil and 1.25 mL of copaiba oil.
