AbstractGray mold isacommon disease in strawberry production,which can reduce the yield and quality of strawberry and cause certain economic losses.The pathogen and symptoms of strawberry gray mold,the infection cycle of the disease,the main factors influencing its occurrence,and comprehensive control measures were elaborated.There are many types of pathogens causing strawbery gray mold, mainly including Botrytis cinerea, B. caroliniana,and B sinoviticola,etc.The maindamageis tothefruit,initiallshowing water-soaked spots,andlater expanding into graybrown soft rot spots covered with mold; infected flower organs,leaves,and petioles show browning,rotting,and mold. The pathogenmainly overwinters inthe form ofconidia,mycelium,or sclerotia in diseased residuesand soil,and spreadsthrough air currents,water vapor,or agricultural operations,infecting plants through wounds or natural openings,and repeatedlyreinfecting ina humid environment.The main factors influencing the ocurrnce of this diseaseincludevarietyresistance,fruit maturityand whether itisdamaged,theamountof bacteriacarriedbyvarious plant organs,environmentalconditions (temperature,humidity,theamountof spores in theair),and cultivationand management measures (close planting，poorventilation,excessive nitrogen fertilizer application，and continuous cropping).In production,itis recommended toadoptcomprehensive control measures including agriculturalcontrol measuressuch as selecting disease-resistantvarietiesandhigh ridge mulchingcultivation,ecologicalcontrol measures such ashigh-temperature fumigation,biological control measuressuch asapplyingantagonistic bacteria (such as Bacilus subtilisand Fusarium lateritium Pa2)and plant-derived agents (eugenol,carvacrol),and chemicalcontrol measuressuch asalternating useof low-toxicand highlyefective fungicidessuch asprocymidoneand boscalid to efectively controlthe occurrence of strawbery gray mold.In the future,systematic research needs to beconducted in areas such asresistancemonitoring systems,developmentof environmentally friendly fungicides,and disease monitoring and early warning systems to provide references for the control and in-depth study of this disease.
