AbstractBasedon the surveydata of wheat scab （Fusarium head blight）in Xuanzhou region from 2O14 to 2024，the disease's occurrence patterns and influencing factors were systematicallyanalyzed，and prevention and control suggestions were putforward.Surveys onthe pathogen-carrying rate ofricestubble anddisease incidence were cariedout in majorwheat-producing areas，andthe diseased earrate and disease index were measuredandclassified in accordance with standards.Theresults showed that wheat scab occurred in Xuanzhou region every year，withthe initial symptom appearance period concentrated from late March to early April.Theseverityof the disease varied significantly among differentyears，and thenumberofrainydays inApril was thekeymeteorological influencing factor.Moreover，thefinal severityofthe disease was notrelated tothe timingofsymptom appearance.Themain disaster-causing factors included the increase in environmental pathogen sources dueto fullstraw incorporation，thehighcoincidencebetween the wheat flowering periodand the peak periodof spore release，and the limited disease resistanceof the planted varieties.In conclusion，to minimize the damage caused by wheat scab，comprehensive prevention and control measures should be adopted，suchas deep ploughing to eliminate stubble，sowing atthe appropriate time，selecting disease-resistantand -tolerantvarieties，and scientificallapplying pesticides during the flowering period.This study provides a theoretical reference for the subsequent prevention and control of wheat scab in related regions.
