Abstract： Wheat sheath wilt is one of the main diseases in wheat production. The occurrence of the disease is affected by multiple factors such as climate，farming system，pathogenic bacteria， etc. At present， the control of wheat sheath wilt mainly includes breeding resistant varieties， agricultural management，chemical control and biological control. In this paper，1 819 articles related to wheat sheath blight prevention and control were collected from CNKI and Web of Science databases published from 2Ol9—2024. 13 papers meeting the criteria were selected according to the established screening criteria. Excel was used to classify and sort the relevant data of chemical pesticides， biopesticides and biocontrol bacteria for the prevention and control of wheat sheath blight. Meta-analysis was used to conduct integrated analysis on the application mode， different time after medication，biopesticides and chemical pesticides. The results show that the heterogeneity of experimental data is large. Biopesticides such as Bacillus bellesiensis LQ-3 had the same control effect as chemical Coolas. The control efficiency of 30g/L phenacetoconazole suspension seed coating agent and 0.8% nitrile and pentazolol seed coating agent was 80% and 81% ， respectively， showing good control efficiency. In the analysis of control effect at different time after application，the control effect of 37% Jinggang ⋅⋅ Bacillus cereus wettable powder was 72% ， showing the highestcontrol effect. The study provided a theoretical basis for the comprehensive control of wheat sheath blight.
