초록

Vapours from origanum oil (O) and thyme oil (T) were applied to the four soil-borne strawberry pathogens Fu-sarium oxysporum f. sp. fragariae, Colletotrichum fructi-cola, Lasiodiplodia theobromae, and Phytophthora cacto-rum, 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 re-stored, indicating fungistasis by vapours. However, the mycelial growth of C. fructicola and L. theobromae exposed to the combined O + T vapours have been slight-ly 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. © The Korean Society of Plant Pathology.
