[2] Cultural practices include crop rotation, deep plowing, and avoiding field operations when leaf surfaces are wet.

[2] 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.

[4] Other sanitation, such as using clean seed and removing alternate hosts, such as wild sorghum species, can reduce disease incidence.

[4] Throughout most areas of the Americas, Asia, Africa, and Europe, Ascochyta sorghi causes little crop loss and is considered to have a very low overall impact on sorghum production.

[5] The lack of economic importance of rough leaf spot is thought to be due to the prevalence of resistant varieties.
