Eleven essential oils isolated from higher plant species were assessed against the four isolates of Verticillium fungicola found on fruiting bodies of Agaricus bisporus. Eucalyptus citriodora and Lippia alba oils were more efficacious and completely inhibited the mycelial growth of fungal isolates. L. alba oil was fungistatic and fungicidal at 10- and 20-µL concentrations against all of the isolates, respectively, and was more potent than E. citriodora oil as well as some prevalent synthetic fungicides such as benomyl, ethylene dibromide, and phosphine. Eighty microliters of L. alba oil protected 500 g of fruiting bodies of A. bisporus for up to 7 d from infection of the fungus under in vivo conditions. The findings strengthen the possibility of L. alba oil as a plant-based protectant to enhance the shelf life of A. bisporus fruiting bodies.
对从高等植物物种中分离出的11种精油进行了评估，以对抗在双孢蘑菇子实体上发现的4种黄萎病菌株。柠檬桉油和白千层油更有效，能完全抑制真菌分离株的菌丝生长。白千层油在10微升和20微升浓度下分别对所有分离株具有抑菌和杀菌作用，并且比柠檬桉油以及一些常见的合成杀菌剂如苯菌灵、二溴乙烷和磷化氢更有效。在体内条件下，80微升白千层油可保护500克双孢蘑菇子实体长达7天免受真菌感染。这些发现增强了白千层油作为一种植物源保护剂来延长双孢蘑菇子实体货架期的可能性。
