AbstractThe occurrence and characteristics of wheat scab in Shouxian，Anhui Province were summarized，the contributing factors wereanalyzed，andcontrol measureswere outlined integrated.Wheatscab isatypical climatedependent disease，primarily causing head blight in the study area.Its occurrence was closely associated with weather conditions during the wheat headingand flowering stage （April1O-3O）；theyearsof major，moderate，and mild occurrence of wheat scab inthe study area from 2O14 to 2024 were 2，3，and6years，respectively.The incidence of thisdisease is mainly influenced byvariety susceptibility，cultivation practices，and meteorological conditions.In he studyarea，the widely cultivated mid-to-late maturing white wheatand someredwheat varieties are highly susceptible tothedisease.The tight rice-wheat cropsuccessonsystem，combinedwith full straw retention，providesa favorableenvironment for pathogenoverwintering.Moderate to severe epidemicsare likely tooccur whensuitable temperatureand humidityconditions coincide with the headingandflowering stage.Based onthis analysis，integrated control strategies were proposed.These include selecting resistant varietiessuch as Zhenmai 18 and Ningmaizi 126 based on local conditions;implementing supporting agricultural measures such as deep straw burial，trenching for humidity reduction，andrational crop rotation;applying precise chemical control during key prevention windows according to climate predictions;and in epidemic years，initiating the firstsprayattheearly heading stage followed by 2-3consecutiveapplications，prioritizing highly effectiveagents likeprothioconazoleand pydiflumetofen. Simultaneously，the“one-spray，multiple-promotion”approachand unified prevention and control should be promoted to ensure maximized and stable control eficacy.This study provides a reference for wheat scab managementand safe production.
