AbstractBased on the wheat production practices in Lingbi County，Anhui Province，the causes ofFusarium head blight were analyzed，and integrated management strategiesfor thisdisease wereexplored.Thepathogensof wheat Fusariumheadblightwereprimarilyspreadthroughaircurents，rainwater，insects，seeds，soil，andfarmingoperatios. The occurrence and severity of the disease were exacerbated by improper straw return，uneven or shalow land preparation，por varietal resistance，unsuitable planting paterns，rainy weather during heading and flowering stages， and improper water and fertilizer management.The control of this disease requires an integrated management strategy. Agriculturalcontrol measures includetheremoval orpulverizationand incorporationof strawinto thefield，mechanical dep plowing and land preparation（2O-25cm），croprotation，sowing atappropriate times，selection of disease-resistant varietiessuchas Zhongke166，establishment ofanearly warning system，andoptimization of cultivation practices. Biological control involves theuse of beneficial microbialagentssuch as Bacillusspp.toinhibit thegrowth and reproductionof pathogensthroughcompetition，antagonism，orinductionofresistance.Forchemicalcontrol，eficient compound agents such as cyanacrylame + tebuconazole were applied using machinery such as plant protection drones during the initial heading and flowering stages，with emphasis onrotating chemicals to ensure efectivenessThis study provides a reference for the integrated control of wheat Fusarium head blight.
