Abstract Grey leaf spot of maize, (Zea maydis L.) (Cercospora zeae-maydis) Tehon and Daniels, is one of the most destructive leaf diseases of maize. The distribution and severity of grey leaf spot has increased over the past 10 to 15 years. The United States and South Africa are main areas where research on the disease has been concentrated. The research results have provided valuable and significant insight into pathogen epidemiology and allowed an integrated management system to be developed. However, management options are a result of the agricultural system under which maize is produced. The pathogen survives only on maize, so crop rotation and stubble management are major factors in disease management, but resistant hybrids offer the best option for economic control. Many other factors, such as soil fertility, plant density, irrigation and chemical control, can significantly influence a grey leaf spot epidemic, although a single management practice will not control the pathogen effectively.
