"ascochyta sorghi" is controlled through host plant resistance, cultural practices, and chemical application when necessary. varieties of sorghum are not generally susceptible to rough leaf spot, although exceptions do exist. cultural practices include crop rotation, deep plowing, and avoiding field operations when leaf surfaces are wet. as "ascochyta sorghi" survives in plant debris and pycnidia in the soil, crop rotation and deep plowing allow for the avoidance of potential inoculum sources. other sanitation, such as using clean seed and removing alternate hosts, such as wild sorghum species, can reduce disease incidence. spores are spread from water splash, and can also be transmitted through contact with field equipment, especially when leaves are wet, so delaying field operations until plants are dry can help prevent spread of the pathogen. if necessary, the application of fungicides can help limit disease severity.
