"ascochyta sorghi" is found in all sorghum growing areas. 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. the lack of economic importance of rough leaf spot is thought to be due to the prevalence of resistant varieties. however, there are a few areas where it may be more prevalent. some states in india, such as madhya pradesh, have seen severe outbreaks of "a. sorghi", where it has the potential to become epidemic. weimer et al. (1937) reported that a. sorghi had the capacity to become damaging in georgia. historically, rough spot has been responsible for crop losses between 3 and 10% in french equatorial africa.
