Vapours from origanum oil (O) and thyme oil (T) were applied to the four soil-borne strawberry pathogens Fusarium oxysporum f. sp. fragariae, Colletotrichum fructicola, Lasiodiplodia theobromae, and Phytophthora cactorum, causing Fusarium wilt, anthracnose, dieback, and Phytophthora rot, respectively. Increasing T vapour doses in the presence of O vapour strongly inhibited mycelial growths of the four pathogens and vice versa. When mycelia of F. oxysporum f. sp. fragariae and P. cactorum exposed to the combined O + T vapours were transferred to the fresh media, mycelial growth was restored, indicating fungistasis by vapours. However, the mycelial growth of C. fructicola and L. theobromae exposed to the combined O + T vapours have been slightly retarded in the fresh media. Prolonged exposure of strawberry pathogens to O + T vapours in soil environments may be suggested as an alternative method for eco-friendly disease management.
牛至油（O）和百里香油（T）的蒸汽被施加到四种土壤传播的草莓病原体上，分别是尖孢镰刀菌草莓专化型、胶孢炭疽菌、可可毛色二孢和恶疫霉，它们分别导致枯萎病、炭疽病、枝枯病和疫霉根腐病。在存在O蒸汽的情况下增加T蒸汽剂量会强烈抑制这四种病原体的菌丝生长，反之亦然。当尖孢镰刀菌草莓专化型和恶疫霉的菌丝体暴露于O + T混合蒸汽后转移到新鲜培养基中时，菌丝生长得以恢复，表明蒸汽具有抑菌作用。然而，暴露于O + T混合蒸汽的胶孢炭疽菌和可可毛色二孢的菌丝体在新鲜培养基中的生长略有迟缓。在土壤环境中让草莓病原体长时间暴露于O + T蒸汽中可作为一种生态友好型病害管理的替代方法。
