Abstract：The application of sulfuryl fluoride in tobacco storage pest control was studied.The 99% sulfuryl fluoride gas preparatioinLongkou CityChemicalPlantwasselected.Thedevelopmentoftobacostoragepestswasanalyzed，andtheconcentration of SO in tobacco stacks at different time periods was detected. The control effect of SO on storage pests was judged through the changes in core concentration and spatial concentration before and after SO fumigation.After SO fumigation，the insecticidal rate reaches 100% ，the pupa mortalityrate reaches 100% ，and the egg hatching rate isreduced to 0% . The pest control effect is better. Using SO fumigation technology can increase the internal circulation device，make the concentrationinthetentmorebalancedstrengthenthefumigationefect，andplayanimportantroleinensuringtheqalityoftobaco storage.
