Currently, researchers are looking for ways to replace synthetic pesticides with substances of natural origin. Essential oils are produced by plants, among other things, to protect against pathogens, which is why there is interest in their use as fungicides. This experiment assessed the composition of essential oils from a commercial source, their impact on the development of mycelium of pathogens of the genus, and the possibility of using them as a pre-sowing treatment. Grains of winter wheat ( L.) and corn ( L.) were inoculated with a suspension of mycelium and spores of fungi of the genus and then soaked in solutions containing oils of sage ( L.), cypress ( L.), cumin ( L.), and thyme ( L.). The obtained results indicate that thyme essential oil had the strongest effect on limiting the development of pathogens and seedling infection, but at the same time it had an adverse effect on the level of germination and seedling development of the tested plants. The remaining essential oils influenced the mentioned parameters to varying degrees. Selected essential oils can be an alternative to synthetic fungicides, but they must be selected appropriately.
目前，研究人员正在寻找用天然物质替代合成农药的方法。除其他外，植物产生精油是为了抵御病原体，这就是为什么人们对将其用作杀菌剂感兴趣。本实验评估了一种商业来源的精油的成分、它们对属病原菌菌丝体发育的影响，以及将其用作播前处理的可能性。冬小麦（L.）和玉米（L.）的种子用真菌属的菌丝体和孢子悬浮液接种，然后浸泡在含有迷迭香（L.）、柏木（L.）、孜然（L.）和百里香（L.）精油的溶液中。所得结果表明，百里香精油对限制病原菌的发育和幼苗感染的作用最强，但同时对所测试植物的发芽和幼苗发育水平有不利影响。其余的精油对上述参数的影响程度不同。选择的精油可以替代合成杀菌剂，但必须进行适当选择。
