Abstract

Maize (Zea mays L.) productivity is severely impacted by ear rot diseases, primarily Fusarium ear rot (FER) and Aspergillus ear rot (AER). These diseases not only reduce yields but also lead to mycotoxin contamination, posing significant health and economic risks. Favourable environmental conditions, insect damage, and agronomic practices contribute to disease severity. Integrated management, including host plant resistance, cultural and biological control, and judicious chemical applications, is crucial for disease mitigation. Sustainable pre- and post-harvest strategies can minimize mycotoxin contamination, ensuring food safety. This article highlights the epidemiology, symptoms, and management of maize ear rots to support sustainable maize production.
