Impact of different concentrations of Eos on the presence of Alternaria sp. on seedlings of A. officinalis of different ages: a 0.002%; b 0.02%; c 0.2%; d 0.5%; e 1%. Seed age: 1 year (2020Y1), 2 years (2019Y2) and 3 years (2018Y3). Eos: oregano Eo, cinnamon Eo, basil Eo, caraway Eo, mint Eo, lavender Eo; E‒emulsifier PEG‒40 hydrogenated castor oil; W Water, H2O Ø. For all seed ages, Tukey's Multiple Range test a, b,… x, significant effect p ≤ 0.05; standard error of the differences of means (± SED)
