The chemical composition and antifungal activity of bay leaf, cinnamon, clove and oregano commercial oils against three fungi were studied. The oils were identified through GC-MS. The essential oils presented a high percentage of oxygenated components: in bay leaf, 78.8% (eucalyptol 51%); in clove, 90.3% (eugenol 89.8%); in cinnamon, 92% (eugenol 60% and eugenyl acetate18.3%); in oregano 71.8% (carvacrol 49.6% and thymol 21.2%). Monoterpenes and sesquiterpenes were: 18% in bay leaf, 9% in clove, 5% in cinnamon, 25% in oregano. Cinnamon, clove and oregano oils reduced fungal growth by 70%, 80% and 90% respectively. The effect of oregano essential oil on fungal development in inoculated rice grains was tested in vivo by exposing inoculated and control rice kernels to essential oil vapour. Oregano, clove and cinnamon oils could provide an alternative for controlling Bipolarisoryzae, Fusarium culmorum and Fusarium sambucinumin rice, cereals and stored products.
