草莓在我国各地广泛种植,由于大规模连作栽培,导致草莓病害逐年增加,根部病害尤为严重。草莓根腐病是最常见的根部病害,目前已发现的病原菌种类有20多种(张悦丽等,2015)。各地草莓根腐病病原菌并不相同,如北京市昌平区为立枯丝核菌Rhizoctonia solani、胶孢炭疽菌Colletotrichum gloeosporioides、木贼镰刀菌Fusarium equiseti、尖孢镰刀 Strawberries are widely planted around our country. Due to large-scale continuous cropping, the incidence of strawberry diseases is increasing year by year. The root diseases are particularly serious. Strawberry root rot is the most common root disease and more than 20 pathogen species have been discovered so far (Zhang et al., 2015). Strawberry root rot pathogens are not the same throughout the country, such as Beijing Changping Rhizoctonia Rhizoctonia solani, Colletotrichum Colletotrichum gloeosporioides, Equisetum Fusarium equiseti,
