[Objective] The aim was to find the best preventing method of Maryland tobacco brown spot to adopt Wufeng County,Hubei Province.[Method] Control technology of Maryland tobacco brown spot in Wufeng was studied in four aspects,such as altitude,varieties,transplanting,and pesticide application technology.[Result] The incidence of tobacco brown spot disease was lower in low altitude height tobacco area.The three Maryland tobacco cultivars like Wufengl,Md872 and Md609 were middle-resistance to tobacco brown spot.The tobacco brown spot indexes of transplanting young seedlings under film and well-cellar transplanting method were decreased by 8.81 and 8.98 compared with control.Medical effect of the field experiments showed that 600 × thiodiazole-copper and 750 × thiophanate-methyl had the best controlling effect on tobacco brown spot,with control efficacies of 98.41％ and 98.58％ respectively.The better ways were 200 × nongyonglianmeisu and 600 × dimetachlone,with control efficacies of 96.48％ and 97.32％ respectively.[Conclusion] The results provide reference for comprehensive control of Maryland tobacco brown spot.
