摘　　要：草莓(Fragria ananassa Duch)是蔷薇科草莓属植物,因其丰富的营养价值和较高的经济效益而被广泛种植于世界各地[1]。随着草莓产业的迅速发展,特别是设施栽培特殊环境及草莓的连茬种植,导致草莓根腐病逐年加重,对我国草莓产量增长和品质提高造成了严重威胁[2-3]。Strawberry root rot is one of main diseases on strawberry in Shandong Province.In recent years,a new root rot was observed on strawberry in Jinan and Weifang,causing approximately 5%-15%economic loss across the survey area.In order to identify the pathogen,17 isolates obtained from the diseased samples and the purified cultures exhibited the same morphological characteristics.Pathogenicity tests for the representative GM204 revealed that this fungus was the causal agent of the disease.Based on morphological characteristics,verification of Koch's postulates and homology analysis of the ITS and LSU sequences,the pathogen was identified as Mucor irregularis.To our knowledge,this is the first report of root rot on strawberry caused by M.irregularis in Shandong.Our findings will provide basic references for disease management of this pathogen.
