effect of essential oil of satureja khuzistanica jamzad and s. rechingeri jamzad, carvacrol and benomyl on growth inhibition of botrytis cinerea pres.: fr., an agent of gray mold disease of fruit

to investigate the antifungal effects of essential oils of khuzestani savory (satureja khuzistanica jamzad), rechingeri savory (s. rechingeri jamzad), carvacrol and benomyl on botrytis cinerea, this study was carried out in a pda medium, and on grapes, kiwi fruits and strawberry. the experiment was laid out factorially based on a completely randomized design with three replications. the results showed that essential oil of khuzestani savory, carvacrol and benomyl had greater antifungal effects compared with that in essential oil of rechingeri savory. the main components of essential oil of khuzestani savory were carvacrol (91.16 percent), p-cymene (1.26 percent), γ-terpenen (0.74 percent). the main components of essential oil of rechingeri savory were carvacrol (77.2 percent), p-cymene (1.26 percent), γ-terpenen (1.62 percent). essential oil of khuzestani savory with concentrations of 200 ml, carvacrol and benomyl in all concentrations used showed 100 percent fungal inhibitory effects. the results of experiments in medium and on fruits showed that the antifungal effects of essential oils increased as their concentration increased.
