The inhibition effect of Satureja hortensis derivatives (essential oil, hydrosol, ground material and extract) on mycelial growth of Sclerotinia sclerotiorum and Colletotrichum circinans were determined in vitro conditions. Of derivatives tested, the extract completely inhibited the mycelial growth of fungi, and showed a complete fungicidal effect on fungi. Essential oil of summer savory on growth of C. circinans were less effective than S. sclerotiorum. The hydrosol of summer savory shown similar effect against on the mycelial growth of both fungi. While the 1.5% level of ground material of summer savory inhibited 100% of mycelial growth of C. circinans, the 0.5% and 1% levels inhibited less. The 0.5% and 1.0% concentrations of ground materials of summer savory on growth of C. circinans were less effective than S. sclerotiorum. The high fungistatic effect in the beginning of incubation was decreased gradually towards the end of incubation.
