Abstract:

The pathogen and symptoms of sesame stem spot blight were described, and the epidemic regularity of sesame stem spot blight was introduced from the aspects of occurrence condition, transmission route, epidemic time and the relationship between climatic conditions and the disease. The agricultural control measures of sesame stem spot blight were introduced from the aspects of selecting resistant varieties, strengthening field management and rational crop rotation. The main fungicide control measures were introduced from seed treatment, soil disinfection, fungicide inhibition and pesticide control. It is suggested that the comprehensive prevention and control model of sesame stem spot blight should be based on the selection of agricultural control measures, i.e. disease-resistant varieties, scientific management and rational crop rotation, and opportunely take chemical control measures, i.e. soil disinfection, seed treatment and fungicide spraying, which can not only control the development of the disease but also meet the demand of people for green food.
