What disease mostly attacks groundnuts?

The disease that predominantly affects groundnuts (peanuts) is leaf spot, caused by various fungal pathogens such as Cercospora species. This disease leads to the development of dark spots on leaves, which can hinder photosynthesis and reduce crop yields. Other notable diseases include root rot and aflatoxin contamination, which can also significantly impact groundnut production. Proper crop management and disease-resistant varieties are essential for minimizing these issues.
